Handyman Tips – San Jose – Fixing Your Toilet – Replacing the Flush Valve
A prior article described how to remove and replace the fill valve, which is to the side (generally left side) of the toilet tank.
Sometimes, your toilet runs because the flush valve, which opens to allow the water in the tank to move into the bowl, is not sealing properly
Changing out this valve is more involved than changing out the fill valve, so if you are doing this, just replace everything.
The incremental effort required to replace everything is next to nothing.
Here is the procedure:
- Shut off the water at the wall.
- Place a container to catch water below the tank.
- Disconnect the supply line from BOTH the valve in the wall and the bottom of the fill valve.
- You will be replacing the supply line, not because it’s broken per se, but because it has built in rubber washers that compress as you tighten it, and the old supply now has compressed washers which might later leak.
- Since the cost of a new supply line is nothing compared to the cost and hassle of water on your floor, you replace the supply line.
- This next step is generally the hardest one – loosen the bolts that hold the tank onto the bowl.
- If they have not been replaced for years they may be seized.
- The top is generally slotted for a very large slotted screwdriver.
- The nut is on the bottom.
- Use vice grips to securely grab the nut, such that when you turn the screw, the nut and the vice grips turn until the vice grips hit something and stop turning.
- Once that happens, turning the screw looses it from the nut.
- Use a properly sized screwdriver even if you have to go buy one, and go slow.
- Lift the tank off the bowl, and place on a towel.
- Remove everything connected to the tank.
- Go to the store and get a full rebuild kit (includes new fill valve, new flush valve, new tank bolts, new everything) and a new supply line.
- Return home and re-assemble per the manufactures instructions.
- Pay particular attention to the order of the gaskets, seals, and nuts for the flush valve.
- Connect the new supply line and test it out.
