Know the Importance of Water Pressure and Flow You may not be aware of it until it weakens, but water pressure is among the critical factors when assessing the quality of flow. You might notice that the pressure is weak or unsatisfactory when the water in the shower trickles and barely gets you wet, or when you have to wait for several minutes just to get the basin or the bath to fill up. It can be frustrating when the pressure in your shower weakens just because someone is using the tap from another bathroom or kitchen. Thames Water is supposed to provide 12 litres per minute of incoming flow rate. Most properties in London get that, and many are able to exceed it. However, there are those that do not, and in some cases, a household may find 12 litres per minute to be insufficient. If you are not satisfied with your water pressure, consider getting in touch with a professional plumber. How is water pressure tested? Professional plumbing engineers will investigate the incoming mains and determine the flow and pressure rates by testing. They will also look into old problems on the line to rule out anything that may restrict the flow. Solutions for poor water pressure and flow When taking steps to improve flow and pressure, it is important to ensure that any solution is done legally. A good plumbing engineer can fit a main boost pump that should improve the pressure to 12 litres per minute, in case they find that it is lacking. From there, they can recommend other solutions that could boost pressure and flow to all the bathrooms and kitchens in the property. Booster pumps may be fitted to the whole bathroom or individual showers, and pumps can be fitted to every outlet. Charger pumps and accumulator tanks may be installed for new pressurised cold water storage and pump fixtures in larger properties. That way, cold water can be stored at a high pressure in big
