Step 1
First, tighten all connections. If the leak persists, determine the leak's source by drying everything with a towel, then looking and feeling for water.
-
Step 2
Turn off the water supply to the toilet, flush to drain the tank and sponge out any remaining water.
-
Step 3
Use a wrench to disconnect the supply-tube coupling nut and remove the fill valve's mounting nut (see illustration in How to Stop a Toilet From Running).
-
Step 4
Lift out the fill valve to clean the gasket and washer. If either is damaged or dried out, replace it.
-
Step 5
Reseat the valve, carefully centering it in the hole and holding it vertical as you tighten the mounting nut about a half turn past the point of full contact.
-
Step 6
Reinstall the water-supply tube and turn on the water to test it. If necessary, tighten the mounting nut a little more.
-
Step 1
Drain the tank and supply-tube coupling as described in step 1, above. Remove the tank's mounting bolts using a large standard screwdriver on the bolt and either a socket wrench or channel type pliers on the nut (see illustration in How to Stop a Toilet From Running). Lift off the tank.
-
Step 2
With the tank upside down, pull or twist off the rubber spud washer and use a spud wrench to unscrew the large locking nut from the flush valve.
-
Step 3
Lay the tank on its side and remove the flush valve.
-
Step 4
Remove the beveled cone washer from the flush valve. Clean it and the spud washer with a soapy sponge (or replace them if they are in poor condition).
-
Step 5
Reverse the procedure to reinstall the tank. Make sure the beveled side of the cone washer is facing the tank's inside and the beveled side of the spud washer is facing the bowl.

on 2/18/2007 Nut frozen to bolt holding toilet to floor, bolt spins with the nut when turned. What's best way to remove nut
Any plumbers out there?
We have a cracked toilet I need to replace. As luck would have it, one of the NUTs on the bolts fastening the toilet to the floor is frozen to the bolt AND the BOLT is just spinning with the NUT when turned.
I'd like advice on how to remove the NUT so I can remove and replace the toilet.
Secondarily, the BOLT spinning isn't good news either, what should I anticipate needs to be done there to secure or replace it.

on 10/1/2007 A leaky toilet tank can cause damage.
Find the leak:
1. Check the ballcock (fill valve) for leaks where it attaches.
2. Dry the tank with a towel, then check for leaks at the tank bolts.
3. Flush the toilet, to check for leak at the tank gasket.
In most cases it will be 1 of these 3 places. If it's the flush valve or a crack in the tank, see the previous article.
1-a. For a simple ballcock leak, tighten it up, or replace it making sure it's tight to the tank.
2-a. For tank bolt leaks, the bolts will usually be corroded and the nut will be rusted so the whole thing will spin. You will need to use a reciprocating saw to cut off the nut and bolts from the bottom. A hacksaw might work, but you'll probably have to take the blade out and wrap it with duct tape to use it.
3-a. For a tank gasket leak, follow the above for removing the tank bolts, as you'll have to remove the tank. Buy a new gasket and new tank bolts and reinstall.
