Leak from toilet base

mac66 · Jan 10, 2008

Noticed that my toilet is leaking just a bit on the back end of the base. Cheked the hose for the water and thats not it. also checked the bottom of the tank to make sure it wasnt cracked and that was ok. Could this be the wax ring?

TIA

yes, among other things. Pray it's the wax ring.

What else could it be?

There could be a crack in the toilet base. If so, you're buying a new toilet.

how can I tell if the base is cracked?

Put some food coloring in the tank and flush the toilet to see if it shows up there. You want to see it coming from a loose tank bolt or the tank to bowl connection - those are fixable.

Could it also be the drain pipe?

On top of the floor, it would not be the drain pipe, but it could be the seal. I suppose it could be a rusted out flange.

Does the toilet rock at all? If so, take it off, replace the seal, shim it first so it doesn't rock.

Turn off the stop valve and see if either the tank or the bowl drains overnight. That will tell you if you've got a tank or bowl leak and you can go from there. If neither drains, it's leaking only during the flush, which is either a bowl leak, or a wax seal leak. In either bowl leak scenario, you're almost certainly going to have to replace the bowl.

Replacing the wax seal is no big deal, but has to be done right.
