Toilets are usually a pretty reliable piece of plumbing. Many times they last for 40+ years without having any problems. But, occasionally, water will begin to leak out from under the toilet and spill onto the floor, which can lead to serious water damage. But this type of leak is easy to diagnose and fix, even if you’ve never attempted a plumbing repair. The leak is usually caused when the seal under the toilet fails.

WHERE IS THE LEAK?

Water pooling around the base of the toilet is a good sign that the wax seal is leaking. That is not always the case though. Soak up the water from the floor with a sponge and dry off the toilet with a towel. Wait until a new puddle appears on the floor, then check to make sure the water is coming out from under the toilet and not coming from a loose supply tube, faulty shut off valve, cracked tank or bowl. If water is leaking from under the toilet, you might be able to stop it by simply tightening the closet bolts that secure the toilet to the floor. Remove the plastic that covers the bolts, then use a wrench to alternately tighten each bolt, a little at a time. Be careful not to apply too much pressure as you can crack the toilet’s base. This might stop a leaking toilet but if tightening the bolts doesn’t help, you’ll have to remove the toilet and replace the wax gasket. If you have ongoing leaking problems with your toilet we recommend calling a plumber in your area to professionally assess the problem and repair it properly.
