How To Fix a Leaking Toilet

Toilet Leak Areas
A leaking toilet (WC) is a serious problem that needs to be fixed as soon as possible to prevent any moisture damage to your bathroom?s subfloor. There are 4 location where you could see a tioilet leak.

A. Leak at the shut off valve B. Leak at the water inlet to the tank C. Leak at the tank / base joint at the rubber gasket D. Leak where the toilet attaches to the floor with a wax ring (see photo)

There may also be a leak that allows water to escape the tank and drain into the base. This leak requires the replacement of the flushing mechanism including the rubber flap that seals this area. This leak wastes water and can cause a serious problem in conjuction with a leak at the wax ring (D). The combination of two leaks will allow continuous water flow into the subfloor.

It?s best to begin the repair by first ensuring that all connections are tight. This will usually fix A and B. If the outside of the tank drips, it is probably condensation, and can be fixed by insulating the inside of the tank with foam panels. If the tank is cracked, it must be replaced. If there is water seeping at the base of the toilet, this can be caused by an old wax ring that no longer seals properly against the drain. If the seeping is constant, this is caused by a cracked toilet base and needs to be replaced immediately. Many toilets are sold with valves and parts already installed so be sure to check that no additional parts are necessary when purchasing your toilet.

What You Need: Materials: rag, plumber's putty, toilet liner kit, wax ring, and abrasive cleanser Tools: putty knife, screwdriver, adjustable wrench, ratchet wretch, and sponge
