REPAIR A TUB SPOUT DIVERTER By Tom Matthews In a tub and shower combo, the diverter is the device that switches the flow of water from the tub spout to the shower spout and back again. It is a simple device inside the tub spout that usually consists of a small chrome-plated handle, a plastic gate, and a rubber washer that seats inside the gate. DIVERTER COMPONENTS Over time, the components can wear out or minerals can build up and cause the diverter to malfunction, resulting in leaks or making it difficult to operate. The good news is this is a simple, inexpensive repair that any DIY’er can complete, and it’s not even necessary to shut off the water supply lines. Step 1: With the tub valves turned off, use a sharp utility knife to cut through the silicone seal where the spout meets the shower wall.
Step 2: Turn the spout counter-clockwise to unthread it and remove it from the outlet. If necessary, use a pair of Channellock pliers (while protecting the spout with a cloth) to loosen the connection. Step 3: Hardware stores sell replacement spouts with the diverter preinstalled ($25-$30), however the replacement spouts are often made of a thinner, flimsier metal than the original hardware, so many homeowners prefer to repair the diverter and keep the original spout. Step 4: Inspect the diverter and spout for damage. The washer may have fallen out, the plastic gate may have broken, or the handle might have gotten bent. In the case shown, the gate was intact but limescale and mineral buildup inside the pipe was preventing the gate from opening and closing properly.
