How often should a toilet flange be replaced?

Your toilet flange is designed to last for years without causing any problems, but several things can lead to a failed seal in your flange. One of the most common problems you'll run into is with the wax ring, which keeps water from leaking out of the base of your toilet and prevents sewer gas from entering your home.

What happens if toilet flange is broken?

A broken flange will cause the toilet to move because it is no longer secured to the flange, which is anchored to the subfloor. The constant rocking will likely break the wax seal (located between the toilet and the flange), allowing water to leak onto the substrate and the ceiling below when the toilet is flushed.

Caulk prevents a fouling area. If mop water, bathtub water, or a less pleasant “bathroom liquid” gets underneath the toilet, there is no way to clean it up. Caulking around the base of the toilet will prevent this from happening.

Closet (toilet) flanges must be 1/4" above a finished floor. This is so the wax ring seals properly to the flange and the hub on the toilet. If a proper seal is not achieved it will result in leaking. If the flange is lower than or flush with the floor they make foam rings that cover the distance for a proper seal.
