Toilet flush valve seat repair

The flush valve on most toilets consists of two parts: the flapper and the valve seat on which it rests when it is down. When either the flapper or the valve seat is worn, water seeps from the tank into the bowl, and the fill valve either turns on and off or runs constantly. Not only is this annoying, but it wastes water. The valve seat is not as likely to leak as the flapper, and if it does, it may be due to sediment or mineral buildup, or it may not be properly sealed.

Steps

Turn off the water and flush the toilet. Hold the handle down until no more water flows out of the tank, then sponge the rest into the bowl to empty the tank completely.

Unhook the flapper chain and unhook the flapper from the overflow tube. It may have rubber tabs that you can pull off the overflow tube. Some flapper plates are connected to the pipe by a ring. To remove such a flapper, you must push the ring to the top of the tube and lift it off.

Wipe the valve opening with a clean rag and check its condition. If it is plastic and feels rough, dry it off and sand the roughness with 150 grit wet/dry sandpaper.

Check the sealing ring around the outside of the valve seat. If it feels loose or looks damaged, replace it with a new one. You can buy replacement rings at specialty stores. The simplest rings are self-adhesive and will only stick if the tank is absolutely dry.

Remove the old gasket by grasping it and pulling it out. It is made of stretchy rubber that comes off when stretched.

Wipe the remaining water from the bottom of the tank with a rag, then dry the bottom of the tank with a hair dryer. Set the hair dryer to medium-hot and move it around so you don’t overheat any part of the tank.

Remove the paper from the bottom of the sealing ring and place the ring around the valve seat opening. Press down to secure the ring to the bottom of the tank.

Replace the valve and attach the chain connecting it to the flush handle. Try the handle to make sure it raises the flap all the way, and make sure the chain is not taut when the flap is down. Adjust the chain as needed.

Turn on the water and allow the tank to fill, then test the flush.
