Traditional Irrigation Installation . . . 1-14

Two Systems Are Better Than One Congratulations on your decision to install an automatic irrigation system. An automatic irrigation system will help you create the landscape you’ve always wanted by making sure your plants get the water they need, just when they need it. How many times have you forgotten to water your lawn, or worse yet, over-watered it and ended up with unsightly brown spots and muddy puddles? You could be using up to 50% more water than your yard needs. That isn’t good for your lawn or your pocketbook. The solution is precision watering using an automatic irrigation system which can be adjusted to the different needs of different plantings. You will get a thicker, greener lawn and more beautiful gardens, as you save time and save water.

An example of traditional sprinkler-based and drip irrigation systems. This system uses automatic in-line valves.

There are two different styles of irrigation systems you can use: traditional sprinkler-based systems and drip irrigation systems. The good news is you don’t have to choose between them because they work better together. This is an instance where two really are better than one. Traditional sprinkler-based systems are well suited to watering large areas of grass and areas with similar plants having similar watering needs. They water uniformly by broadcasting water in well defined patterns, five feet or more in diameter. To water smaller areas, we recommend drip irrigation. Drip irrigation, on the other hand, is the ideal complement to traditional irrigation. Rather than broadcasting water over large areas, a drip system is set up to water very small, specific areas. For that reason, drip systems are good for patios, near foundation walls, watering specific plants within larger garden areas and tight, slow-draining clay soils. In so doing, drip systems use little water and discourage weed growth. So, in order to create the best irrigation system possible for your plants, don’t think in terms of traditional or drip; think in terms of traditional and drip. You get the best of both worlds and the very best results.

Getting Started Before You begin

Beginning Your Design

There is no question that planning and installing an irrigation system is a big job, but it is not a difficult one. To make it easier, we have divided the process into just three steps that walk you through the job from beginning to end. They are: Gather Required Information, Map out Your System and Install It.

There are two options for getting a design for your automatic irrigation system: 1. Follow the instructions in this guide and use the layout paper on page 6 to design and draw your irrigation system. OR,

Remember, we’re here to help you. Visit www.toro.com or www.torodesign.com or call 800-367-8676.

2. Let Toro do the irrigation system design for you! See page 4 for more information on Toro’s Sprinkler Design Service. In either case, you will need to complete sections A - D. We suggest you use the following planning tools: pencil, scratch paper, drawing compass, 50’ tape measure, straight edge or ruler, line marking paint for marking trenches, Toro flags for marking sprinkler locations and a Toro Flow & Pressure Gauge.

Check Local Codes and Permit Requirements Before beginning your irrigation project, contact your local water company or the proper municipal authority for information on building codes and required permits. They can also tell you about requirements for the backflow prevention devices required in your area. These devices protect your water supply from contamination and are required for inground irrigation systems.

Warning! Serious injury may result from damaging buried electrical or gas lines. Before digging or trenching, have your local utility companies mark all buried cables, pipes, and gas lines!

✓ Tools And Other Supplies You May Need During installation, you will need several accessories and a variety of pipe fittings. The list below shows other materials you may need: PVC pipe cutter Screwdriver Pipe wrenches Hammer Trenching shovel Line marking paint 1” pipe clamps (poly only) PTFE tape Duct tape Tape measure Solvent, primer, rags (PVC only — do not use pipe dope on plastic-threaded fittings.)  Toro flow and pressure gauge  Marking flags  Toro water-proof connectors or grease caps  18 gauge, multi-strand direct burial wire (number of strands varies depending on the number of zones).

Tip:

If you do not own a flow & pressure gauge, ask your local home center if they have one in their rental center.

Draw Your Property Use the layout paper provided on page 6 of this guide. Each small square on the graph should represent one square foot of actual property or use a scale such as 1 inch = 10 feet, 1 inch = 20 feet, etc. Using the tape measure, measure your property and draw it to scale on the layout paper. Use the drawing below as an example.

          

Remember: • Outline your house, garage, and other structures. • Show walkways, drives, slabs, patios, and other surfaces. • Identify trees and major obstacles. • Measure and record the perimeter of your property. • Identify any slopes. • Show groundcover, grass, flower beds and landscaping. • Identify the size and location of the water meter (or pump) and main line. • Identify the type of soil in your yard: sand, loam, or clay.

Tip:

Be sure to double check all measurements.




STeP 1 - GaTher reQuIreD InformaTIon B

DeTermIne Your SoIl TYPe There is a simple way to determine what type of soil – sand, loam, or clay - you have in your yard . All it takes is a clean, empty jar with a lid, some clean water, a tablespoon of detergent, and a sample of the soil you want to test . To do so: • Fill the jar about 1/3 full with the soil to be tested . • Fill the jar with water and detergent then cap it . • Shake the jar vigorously and set aside for several hours or overnight . EMITTER

evaluate the results: a. If the water is clear and the soil has settled to the bottom, you have predominantly sand soil . b. If the water is still murky with bits of matter still suspended in it, you have loam soil . C. If the water is still murky, and there is a visible ring of sediment around the jar, then your soil is mostly clay .

Gather Required Information - Step 1 D

Water flow & Pressure determine your water pressure & flow You can use either of the two methods listed:

1 Using a TORO flow & pressure gauge The Toro Flow and Pressure Gauge is a dual purpose device designed to measure water pressure to 160 PSI and water flow to 13 GPM. This flow and pressure gauge is not intended for use on lines larger than one inch. The gauge will only measure flow through the outside faucet – not in the line. To measure the static pressure: • Make sure no water is being used inside or outside the home. • Attach the flow gauge to the outside faucet nearest to where the main line enters the house. • Make sure the flow gauge is closed by completely turning the handle clockwise. • Open the outside faucet slowly to avoid damaging the flow gauge. • When the outside faucet is fully opened, read the system static pressure and record it below. Record the static system pressure here:

Static PSI __________

2 Using a bucket & STANDARD pressure gauge

• Find the outside faucet that is closest to your water supply line. (Call this Faucet 1) • Select a different outside faucet on your house and attach a pressure gauge. (Faucet 2) • With Faucet 1 closed, open Faucet 2 all the way and record the static water pressure below. • With Faucet 1 open all the way, check the pressure reading on the gauge at Faucet 2. *If it is less than 40 PSI, turn down the water flow from Faucet 1 until the reading reaches 40 PSI. • Place a 5-gallon bucket under Faucet 1 and time how long it takes to fill it. Use the chart below to convert to GPM. This test tells you what your home’s water capacity is measured in GPM at 40 PSI. • Repeat this procedure at 45 PSI and 50 PSI and record these three results on the chart below: This is how much water is available with a working pressure of 40 PSI or the higher reading that you recorded. (Minimum operating pressure for most sprinklers is 35 PSI.)

Note: Static pressure measures the pressure in the system with no water running. It is measured in pounds per square inch or PSI. To measure the dynamic pressure and gallons-per-minute rates: • Continue to open the flow gauge slowly by turning the handle counter-clockwise. *As the flow gauge opens, pressure will drop from the static reading and the gallons-per-minute (GPM) reading will rise. • Open the flow gauge until pressure drops to 50 PSI. • Record the gallons-per-minute reading on the chart below. • Continue to close the gauge to 45 and 40 PSI and record the GPM readings.

Record the GPM indicated on your flow and pressure gauge here:

Record the static pressure here:

Record the GPM here:

______GPM at 40 PSI

If the pressure does not drop to 40 PSI after opening the flow gauge all the way then take the flow and pressure reading at the full-open position. If rapid fluctuation occurs on the flow gauge, record the average reading.

Note: Dynamic or working pressure is the pressure in the system with the water running. The dynamic pressure will determine how far your sprinklers will spray.

Time To Fill Bucket

______GPM at 45 PSI ______GPM at 50 PSI

Note: If you use a different size bucket, time how long it takes to fill it. Convert this to GPM using the following formula: 60 ÷ Seconds x Gallons



For example: A 2-gallon bucket that fills in 15 seconds means the available flow is 8 GPM

60 ÷ 15 x 2 = 8 GPM

______GPM at 50 PSI




Using the Toro design Service

Need a sprinkler system? Let us design one for you. Using the Toro Design Service We want to do everything we can to make the design and installation of your Toro irrigation system a simple, step-by-step project. We’ll create a customized design that includes: • Proper valve, pipe, and sprinkler layout for perfect water coverage throughout your yard • The first thing we will do is divide your yard into areas containing similar plants, lawn and conditions. Is it a high sun lawn area? Is it a sloping garden area, etc? We make sure every plant type and climate in your yard is accounted for (that’s why it is important that you include them all on your landscape sketch). • Correct sprinkler head selection and placement to accommodate every curve and contour of your landscape • We determine the best sprinklers to use in each area. This decision is based on the plants and area being watered. • The sprinklers are positioned so that the spray from each sprinkler head just reaches all those adjacent to it. This is called Head-to-Head coverage, and it is vital to ensuring uniform water application. It is calculated using your water pressure information and performance data for the type of sprinklers selected for each area of the yard. • For planter areas, we incorporate micro-irrigation (also known as drip irrigation) because micro-irrigation saves water and is an effectively way to water the variety of plants found in a planter section.

• Ideal number of irrigation zones and timer location • An irrigation zone is a group of sprinklers (or drip emitters) that operate simultaneously, using one irrigation valve. To determine the number of zones, we again use the information provided by you to be sure the sprinklers we have plotted in each area can be run with the available water flow and pressure. Zones are created when the available water flow and pressure matches the needs of the sprinklers and the rest of the house. What we end up with is the final zone count. • The zone control valves are then grouped together in clusters called “manifolds.” For example, we group all the valves needed to operate the front yard zones together, all the valves for the backyard together, etc. This simplifies installation and maintenance later on. • A complete shopping and parts list of everything that you will need • All you will need to do is buy and install it. If you would like to review some of the Toro products we will use when designing your system and making the parts/shopping list, refer to the Appendix of this book for an overview of Toro Irrigation products.

Now it’s almost time to draw in your sprinklers and emitters on your irrigation plan. Before you do, be sure to consider the following information: • Draw sprinklers within each zone of your plan one area at a time. • Place sprinklers with the greatest radius in larger areas. *Pay attention to the allowable spacing range for the sprinklers selected to create head-to-head coverage. • Always place sprinklers in a way that avoids spraying the side of your house, walls, fences, etc. Also, minimize the water spraying onto sidewalks, driveways and streets. • Place half-circle sprinklers on edges and borders, quarter‑circle sprinklers in corners, and full-circle sprinklers in the middle of spaces. • Use rotor or impact sprinklers to cover large areas. They can distribute water up to 48’. • Use 570 fan spray sprinklers to cover smaller areas. They are effective up to radii of 15’. • Use bubblers or drip irrigation in small confined areas and to water plants individually. • To help in your planning and irrigation component selection, we have included component selection information in the Appendix (pages 23-26) at the end of this manual.

Tip:

Do not mix fixed-spray and rotors within the same zone.

Now it’s time to determine how many zones you will need. A zone is a group of sprinklers (or drip emitters) that operate together using one common irrigation valve. Each valve, and thus each zone, is operated by your system’s timer.

A 1

Write down the flow capacity in GPM for each type of sprinkler in your layout. (see page 27)

2

Next, divide similar sprinklers into groups. • Separate lawn and shrub areas. • Separate shady and sunny areas. *Different sprinkler types apply water at different rates so don’t mix sprinkler types within zones. For example, fixed-spray sprinklers should not be grouped with rotary sprinklers.

3

Add up the sprinkler GPM for each of the zones you have created on your plan. If the total flow exceeds the safe design capacity for your system, split that zone in two, or, if possible, put some of the sprinklers into another zone. Remember to move sprinklers to other zones based on slope, sun, shade or GPM.

Count Your Zones Count up the number of zones you have in your design. That is the number of irrigation valves you will need. In the example on page 8, we will need eight valves because we have eight zones. This will also affect the size timer you will need to buy.

Layout the Valves on your Plan We recommend grouping the valves together. For example, grouping all the valves needed to operate the front yard zones together. This symbol represents a valve location.

Incorrect head-to-head spacing

Determine the correct spacing using the sprinkler radius. For example, if you are using Toro 570™ sprinklers with a radius of 15’, place your sprinklers no more than 15’ apart - closer together if you are in a windy area.

Full Circle

C

Correct head-to-head spacing

Divide Your System To determine the number of zones you need in your system, do the following:

Head-to-Head Coverage For proper coverage, layout your sprinkler heads so that the spray from one reaches all those adjacent to it. Head-to-head coverage ensures uniform water application, which saves water and creates the best possible results. (Refer to diagram.) For areas with winds regularly above 8 mph, place sprinklers closer together — 90% of the spray radius or less depending on the prevailing wind direction and speed.

Create Your Zones

15’ Radius

Half Circle

Locate the first set of valves in a convenient spot near the main water connection. A good idea is to place valves next to walks or in planters for easier access. The example on the next page shows two valve manifold locations. The front valve manifold controls zones 1, 2, 3 and 4. The backyard valve manifold controls zones 5, 6, 7 and 8. It is recommended that the timer be able to control more valves than are called for in your plan. This will make any future expansion much easier. The Toro ECXTRA® expandable timer would be ideal to use in this example.

Quarter Circle

Tip:

To make sure you have proper head-to-head spacing, use a compass to draw arcs representing sprinkler coverage, as shown in the diagram.

Use as many straight runs as possible . Try to avoid turns, which result in loss of pressure . Avoid runs under sidewalks and driveways whenever possible . Make 90 degree connections wherever possible .

noTe:

You can include more than one pipe in a trench.

Depending on local codes and zone GPM , consider using 1” Schedule 40 PVC pipe upstream of control valves and at least 3 ⁄4” Class 200 PVC pipe or 3⁄4” poly pipe downstream .

Draw In The loCaTIon of The TImer Install the timer inside your garage or on an outside wall near a 120 VAC outlet . Toro offers a weather-resistant timer cabinet for mounting in exterior locations . Toro also offers an ECXTRA® expandable timer with an integrated all-weather enclosure to make mounting in exterior locations easier . Check local electrical codes for connection requirement to outside plugs . Use this symbol to reflect the timer location . Place zone or valve wires in the same trenches as the pipe . Remember that the valves will be wired to the timer, so run the valve wires where they will be easily accessible . Toro recommends 18-gauge, multi-strand, direct-burial wire to connect valves to sprinkler timers if the distance is 1000 feet or less (refer to Timer to Valve wire sizing chart on page 28) . You will need one wire per zone, plus the common wire . For instance, this eight-zone system requires nine wires . Be sure to use Toro’s Waterproof Connection Caps or grease caps for all your waterproof connections .

Tip:

Always install 2 or more wires than valves to make it easier to add more valves in the future.

2 If the Meter Is in Your Yard: 1. Shut off your water supply at the meter (check with your water department first). 2. Dig to expose the service line. 3. Tie into the service line, between the water meter and the house. 4. Remove a section of pipe, leaving a gap large enough to slide on a compression tee. 5. Slip the tee over each end of the pipe. 6. Tighten the compression nuts. The rubber gasket will compress against the pipe, creating a seal to prevent leakage. 7. Install a short nipple, using PTFE tape on all threaded connections to the tee. 8. Attach a shut-off valve, in a small enclosure, to this section of pipe. The shut-off valve allows you to turn off the system by hand, if necessary. 9. Keep this connection as clean as possible. This is your tap water supply.

3 If the Meter Is in Your Basement: 1. Shut off your water supply at the meter (check with your water utility). 2. Install an appropriate tee into the service line for the irrigation connection. 3. Drill a hole through the sill above the foundation, or chisel a hole in the basement wall for the irrigation line to run through. Make it no bigger than needed for a 1� pipe. 4. Install the connection fittings, as shown. A ball valve is a good choice for the irrigation shut-off. For the drain valve, use a gate-type valve. The drain valve should be as low as possible to allow complete system drainage. 5. Feed your irrigation system pipe out through the basement wall, and run it to the backflow preventer location (see page 12 for more information on backflow prevention). 6. Finally, seal the hole in the sill or foundation with caulking compound.

They can be rented by the hour, day or week, usually from a lawn supply store or rental equipment dealer . The person you rent from can show you how to operate the machine properly and safely . Trenchers should not be used to dig through ground cover, flower beds, on steep slopes or near buildings . Be sure to verify all underground utilities before trenching . In colder climates a vibratory plow is used for pulling pipe .

noTe: Wait at least one hour before running water through the system. (Check manufacturer’s recommendation.)

2 workInG wITh PolY PIPe 1. Cut pipe with a PVC pipe cutter . 2. Slip a stainless-steel clamp over the end of the pipe . 3. Insert the barbed fitting into the end of the poly pipe, past the barbs . 4. Slide the clamp over the barbs of the fitting . 5. Tighten the clamp .

Self-tapping Saddle (53686)

Tip:

Save time by using the Toro Self-Tapping Saddle for poly pipe (80-100 PSI). No more sawing, drilling or gluing! SelfTapping Saddles are available at your local home center.

Tip:

To relax poly pipe, expose it to sunlight. Never expose poly pipe to open flame.

WArning! Do not use poly pipe as the connecting pipe between the service line and the control valves. Surge pressure may rupture the poly pipe. Be sure to check local codes for correct type of pipe to use.

Do it the easy way, use the Toro Dingo with Trenching Attachment

Step 3 - Install It! E

Build valve manifolds A group of valves running off the same supply line is called a manifold. We recommend grouping your valves into manifolds based on their use or location. For example, one control valve manifold to operate front yard zones and one to operate backyard and/or side yard zones. Use flags to mark the location of the valves, as indicated on your worksheet.

1 Anti-siphon valve installation Anti-siphon valves are backflow prevention valves designed to protect your water supply from contamination. Some sort of backflow prevention is required on every irrigation system, so you need to check the building codes in your area to find out if an anti-siphon valve will work for you. These valves are always installed above ground, so be sure to dig out an area large enough to accommodate your inlet and outlet pipes.

Automatic Anti-siphon Valve Assembly (3/4” valves shown)

In-line valves are installed below ground and should always be installed in a protective valve box. Dig out the area where in‑ground valves are to be installed, and add several inches of gravel to the bottom of the hole. Place the top of the valve box so that it is even with the surface of the ground. When you buy a valve box, be sure to find out how many valves fit in each box so you know how many to buy. In some cases, you will need more than one valve box per manifold.

1” Schedule 40 PVC

Note: If one of the valves will be used for drip irrigation, leave enough room between the valve and the sides of the valve box for the filter and pressure regulator that are part of your drip system. It may be a good idea to install those parts on the valve, then, install the valve in the valve box.

Pressure Vacuum Breaker should be installed 12” above the highest sprinkler, or according to local codes.

Tip:

When putting together your valve manifolds, always include one or two extra connections in each manifold. This makes it easier to expand your system at a later date.

Tip:

Look for valves with the flow control feature. It saves water!

Install It! - Step 3 F

Install Lateral Pipe Start from the valves and move outward, laying the connecting pipe along the bottom of the trench. At each flag, install a tee or elbow fitting, and if needed, a riser for sprinkler attachment. We recommend that you use Toro Funny Pipe® for all your sprinkler head installations. Refer to the Funny Pipe® section for more information.

G

Flush the System to Clear Debris After the pipe has been connected and the glue has dried (PVC pipe only), turn on the water, open valves one zone at a time and flush until the water runs clear. Seal the fitting with duct tape to keep dirt out until the sprinklers are installed.

Note: Don’t backfill your trenches until your final system operation check is complete.

I

Install Drip Irrigation Riser If you are planning to use drip irrigation, now is the time to install the riser(s) that will supply the water to it. As a general rule, locate your riser in the center of the area where the drip system will be used. This will simplify installation later. Installation with Anti-Siphon Valve

Install Your Sprinklers Zone-by-Zone Install one sprinkler zone at a time, using Toro Funny Pipe® to connect to the lateral lines. Remember to refer to your planning worksheet. 1. Placing a sprinkler in a trench as a guide, measure from the connecting pipe fitting to the bottom of the sprinkler and cut a length of Funny Pipe to fit. Place sprinklers at least 3” from sidewalks and curbs and 6” from fences and buildings. 2. Install the appropriate Funny Pipe elbow into the sprinkler and into the PVC or poly pipe fitting. No glue or clamps needed. 3. Connect the Funny Pipe to the sprinkler and to the pipe fitting.

Note: Do not use more than 4’ of Toro Funny Pipe with each sprinkler head. 4. Position the sprinkler in the trench so that the top of the sprinkler is flush with ground level. Stabilize the sprinkler with soil without filling the entire trench. 5. Verify that the sprinkler is vertical for optimum performance. 6. Repeat this process for each sprinkler.

An anti-siphon valve is a combination valve and atmospheric backflow preventor. Check local codes.

An in-line valve often requires a separate back-flow device. Check local codes.

Note: PVC pipe is shown in these illustrations. However, in areas where freezing occurs, poly pipe may be used downstream of valves instead of PVC. Always check local codes for proper pipe recommendations and before installing backflow prevention devices.

Step 3 - Install It! J

Install Your Timer Display Programming Dial Valve Wire Connections Transformer Grease Cap/Wire Connectors Anti-Siphon Valve Sprinkler

1. Install the timer in your garage or another convenient place. If an outdoor location is desired, use an outdoor cabinet to protect the timer against the effects of weather. Make sure an adequate power supply is available. Toro timers require only a standard outlet. (See instructions included with the timer for details.) 2. If you haven’t already done so, lay the valve wires in the bottom of the trenches, beneath the pipes.

Tip:

Installing more wire strands than your system currently requires can be a real time saver. Adding them now is simple, adding them later after all the dirt is back in place and the grass is growing is not.

3. Connect the valves to the timer using the valve wires. a. Take one wire from each valve and connect them to a common wire. (For ease of identification, use the white wire as the common.) b. At the timer, connect the common wire to the common terminal on the timer. c. Take the other wire from each valve and connect them to the timer terminals in sequence. 4. Plug in the timer.

Warning! All outdoor electrical connections must be waterproofed. Use Toro’s Grease Caps/Waterproof Wire Connectors.

K

OPTIONAL: Connecting a Pump Start Relay If your system will get water from a well, water tank, or pond, a pump start relay lets you automatically activate the pump if your water supply requires one. For proper function, the timer must be installed at least 12 feet from the pump and 5 feet from the pump starter to prevent malfunctions. Pump Start Relay

Check your System Operation 1. Slowly turn on the water, then manually open an irrigation valve. 2. Adjust the sprinklers to ensure proper coverage. (See sprinkler installation instructions for details.) 3. If you don’t have complete head-to-head coverage, follow the steps below: a. Make sure the control valve and shut-off valve are fully open. b. Turn off any water being used in the house (washers, showers, faucets, etc.). c. Fine-tune sprinkler spray positions and spray patterns to match your coverage area. d. If coverage is still not complete, go back and check your system layout against the plans. e. When you see that the coverage is satisfactory, fill in the trench. 4. Once you are satisfied with your installation you can move on to installing your drip irrigation system. The following chapter gives detailed instructions for handling this installation.

The Right Timers You are free to use any irrigation timer you choose with your system, and mount it almost anywhere. However, we highly recommend our ECXTRA™ timer. The ECXTRA™ Suite gives you more control and convenience of operation over other timers. When choosing a new timer, there are just a few things to keep in mind while you shop: 1. Can it control all the zones I have now and in the future? Buy a timer that has at least two more zones than you need. That way you are ready for future expansion without replacing the timer. The Toro ECXTRA™ is an expandable timer, meaning that you can add zone capacity to it whenever it is needed. 2. How many different programs should the timer run? Do not buy a single program timer. It is virtually impossible to create an efficient watering schedule for even the smallest lawns with just one watering program. The Toro ECXTRA™ not only has three independent programs to use, but if you use it with the Scheduling Advisor™ software, it sets each program for you to achieve the highest efficiency for your watering needs. 3. How many start times do I need? As with programs, having multiple start times allows for more convenience and efficiency while irrigating. Multiple start times lets you adjust your watering for soil type and plant needs. The ECXTRA’s Scheduling Advisor™ software suggests start times for you, or lets you set your own start times. 4. Should I use an indoor or an outdoor timer? This is usually a matter of preference, more than need. The ECXTRA™ timer, as well as most others come in both versions, or can be mounted in after-market housings for outdoor use.

The ECXTRA™ Finally, Timer Programming Made Simple... and Smart!

E

Expandable ECXTRA™ Timers Introducing the New Toro ECXTRA™ Suite with computerbased irrigation scheduling using a home computer. This innovative system includes the new ECXTRA™ timer, the Time Pod™ transport module, and the Scheduling Advisor™ irrigation scheduling software. The three products work together to bring computer management to your irrigation system using a home computer!

1 Scheduling Advisor™ software The centerpiece of this new product suite is the “intelligent” PC–based Scheduling Advisor™ software. It manages the entire set-up and scheduling process using a personal computer to guide you through several easy steps. Using an intuitive interface, the software collects information about the location of your yard and its unique features, such as sun exposure, prevailing winds, plant types, and even the kinds of sprinklers being used. These factors and several others are used in “behind the scenes” calculations to generate a comprehensive irrigation schedule.

2 Time Pod™ transport module Once the Scheduling Advisor™ software has created a customized schedule, the Time Pod™ transport module comes into play. The Time Pod™ is essentially a flash memory drive that links the home computer to the ECXTRA™ timer. Using a USB port, the Time Pod™ is automatically loaded with the irrigation schedule from the computer. On the other end, the Time Pod™ plugs into a dedicated docking port on the ECXTRA™, where the push of a single button transfers all the information from the Time Pod™ into the timer, leaving the timer set up and ready to be activated.

3 ECXTRA™ timer The third and final component of this system is the ECXTRA™ timer itself. Besides the ability of being programmed using a home computer or manually, it has the following capabilities: • Expandability – The indoor units are expandable from 4 to 10 zones, in 2-zone increments, while outdoor models can be expanded to 12 zones. • Battery-free Backup Protection, using non-volatile memory protects your schedule and settings in the event of a power failure. • Programmable Pump-Start lets the user adjust the delay between irrigation pump start up and irrigation system activation assuring proper water pressure is always available. • 365-day Calendar manages even the most complicated municipal water restrictions. • Seasonal Adjust feature lets the watering schedule be adjusted for changes in local weather, without the need for reprogramming.

How Many Sprinklers Can I Use? When planning an irrigation system, one of the most important tasks the designer does is figure out just how many sprinkler heads can be installed on one zone, given the available water pressure and flow. If too many sprinklers are installed, then when they are all running, there may not be enough water available for them to function correctly. This can also adversely affect the water pressure inside the house. It is better to design your zones so that you have some “excess” capacity in them. Then, if needed, you will be able to add a sprinkler or two later on without needing to change your zones. An important factor in this “How Many Sprinklers” equation is the sprinkler pattern you will use. Are they all 90° Quarter-Circles? Are they Half-Circles? The truth is you will usually be using a mixture of different patterns with different flow requirements. This can make things seem a lot more complicated when you are trying to add the flow up and figure out your total per zone. To help you, we have put together a chart that shows you the maximum number of sprinklers that you can put on one zone, if that zone has a certain amount of water pressure and flow. For example, if you are using 570 spray heads and you have 30 PSI at the head of water pressure to work with (called working or dynamic pressure), you can see that if your system can deliver 5 GPM at that pressure you can use a maximum of one 15’ Full-Circle on that zone, but up to 5 Quarter-Circles. The more flow and pressure you have, the more sprinklers you can install in any zone. For the exact flow by sprinkler type, refer to the Sprinkler Performance Chart on the right.

Frequently Asked Questions Frequently Asked questions

1 System Design

Q: How do I get started? A: You can design your system yourself or take advantage of the Toro Design Service. In either case, you will need some basic information (see pages 1-8).

Q: How long will it take to install my system? A: After you have your completed design and have parts in-hand, it will take an average* of 2-3 days (about 1-2 weekends). *(Average home lot size of ¼ acre)

Q: If I have my plans prepared, how quickly will I get my design?

A: It will take approximately 2 weeks to get your design back. Or for the cost of shipping, you can have your plans sent 2 Day Express (call 800-891-0742). You can check the status of your design, view and print your plans at www.torodesign.com

Q: How much will it cost for my sprinkler system? A: If you have a professional contractor install your system,

you can expect to pay at least 2-3 times more than if you do it yourself. Typical cost for doing it yourself may be between $800 and $1,600*. Every home is different. *(Average home lot size of ¼ acre)

2 Installation

Q: How do I hook up my valves? A: Valves connect to your timer with simple wiring. Each

valve has 2 wires; choose 1 as the zone wire, and the white wire as the Common wire. Use 18-gauge multi-strand wire if the distance between the timer and valve is 1000 feet or less (Refer to the chart below on this page for longer distances). Always use more strands than you need for future expansion. (Wire sold separately.) (see page 14)

Q: When I connect my valves to PVC, do I use glue? A: Most valves will connect to the sprinkler system with a

PVC connector with male threads. Simply screw the male connector into the valve. Use primer to prepare the pipe and fitting, then glue the other end of the PVC connector to the rest of the pipe flowing to your system (see page 11).

Q: How many valves will I need? A: You need 1 valve for each zone. Q: How do I determine what type of valve I need? A: Local water regulations determine the type of valve

you need. Call your local water company to determine what is required in your area (see page 12).

Q: How do I determine what type of timer I need? A: There are four factors to consider:

from one sprinkler head must reach the next sprinkler head (head-to-head coverage). If you space heads too far apart and do not have head-to-head coverage, you will end up with brown spots (dying grass) (see page 7). same zone (same valve)?

A: No. You should avoid mixing small and large area sprinklers on the same zone because they have different watering amounts and will cause over and under watering.

Q: How many sprinklers can I put on one zone (one valve)? A: Your water pressure and water flow will determine the

maximum number of heads that can be used. Too many heads on a zone will create low pressure in your system and will cause the heads to work improperly (see page 27).

Q: What type of pipe should I use to connect the system? A: You can use either Polyvinyl Chloride (PVC) or Polyethylene (Poly) Pipe. In freezing climate areas, you will generally use Poly Pipe. Consult your local codes to find out what’s required in your area (see page 11).

Q: How do I install drip or micro-irrigation? A: You will start by connecting to the water source. In addition to the valve, Drip or micro-irrigation requires a filter and pressure regulator to protect the small emitters (drippers). Then you connect the ½” Drip Hose. Next you decide on the best method to water your plants. Refer to pages 16-21 for more details.

TIPS The tips listed below will help you get the most from your new Toro irrigation system. Please pay special attention to the water conservation tips. Conserving water is not only the right thing to do for the planet; it is also the right thing to do for your budget.

1

Water Conservation • Always use “head-to-head coverage” in your irrigation system. • Keep the soil consistently moist but not wet. This eliminates runoff, and ensures your plants a steady supply of water. • Do not water at night - water will sit on the lawn and may cause disease. • Water in the early morning - evaporation is minimized and the lawn utilizes the most water. • Do not water midday – evaporative loss is at its greatest. • Create multiple programs for your irrigation system – this allows you to water most efficiently. • Install a rain sensor – it will prevent the system from running during rain. • Use drip irrigation in flower beds - it saves substantial amounts of water. • Reduce run times for zones in the shade. • Allow grass to grow before mowing - this reduces water usage. • Practice “grass cycling”- this reduces evaporative water loss from the lawn, while reducing the need for fertilizer. • Sharpen your mower blade - sharp blades are easier on the grass and save water. • De-thatch your lawn - water will get to the roots faster and evaporate less. • Aerate your lawn - it prevents soil compaction and allows water to soak in faster. • Keep plants with different watering needs on different zones – trees vs. lawn, etc. • Plant native species - native plants do better and need less special care than exotics. • Mulch flowerbeds and trees - it reduces evaporation and controls weeds. • Know your soil type - the three basic types: sand, loam, and clay require different watering schedules for optimal results. By implementing these conservation tips, your water use can be cut dramatically.

2

Water Scheduling For best results, create a weekly watering schedule. Figure out your total weekly watering needs (run times). Divide those runtimes into watering days, and if your timer supports multiple start times, by that number. For example, if the weekly watering requirement for one zone is 65 minutes a week, you would water 9-10 minutes every day or 16-17 minutes every other day. It is better to water for shorter periods, but to do it more often. This allows the moisture level in the soil to remain constant. Also, consider the type of soil you are watering. If you have sandy soil, longer runtimes may be better, whereas with clay soils, you will need to apply water more slowly and use more start times. The key is building the most flexibility into your system possible, and using that flexibility to create the most precise schedule you can. Precision equals performance and water savings.

3

Winterization Procedures for Cold Climates The water supply should be turned off at the main valve and the irrigation timer should be set to the “Rain” or “Off” setting. Each valve should be turned on manually to release pressure and water in the pipes. This is done to protect any components that could freeze. Your irrigation system may have manual or automatic drain valves that should be placed in a downward position to facilitate flow and opened for proper drainage. However, your system may still require that it be blown-out using compressed air to ensure all water has exited the system. Do not exceed 50 PSI of air pressure.

Warning! We recommend hiring a professional when winterizing with compressed air. * Follow the recommended winterization instructions included with your sprinkler timer.

Install a Rain Sensor A rain sensor saves water by shutting down your irrigation system temporarily when it rains without erasing your programs. It is easy to attach to roof eaves.

Install Micro-Irrigation Install a Micro-Irrigation system using Toro’s Blue Stripe® Drip Products to save time, money and water. Refer to pages 15-21 for more information.
