What is a Toilet Flange?

A toilet flange is a pipe fitting that secures the toilet to the drain pipe in the floor. When connected the contents of the toilet then run into the sewer system. A flange is all known as closet flange a term that dates back to when toilets where called “water closets.” Toilet flanges are made out of PVC, rubber, or various metals. The flange uses a wax ring and is secured by bolts to tightly seal the flange to the bottom of the toilet. The wax ring creates a water tight seal and keeps toilet from leaking as it passes from the toilet to the drain pipe. It also seals against foul sewer gas odors.

Where does the word Flange come from?

According to YourDictionary, the English word flange (“to project”), flanch (“a projection”), from Old French flanche (“flank, side”). According to some flange “comes from the old French word flanchir which means to bend.”

Are toilets always installed using a Flange?

Yes, without a flange a toilet would not sit properly on the drain line thus causing problems. Leaks and water rot would assuredly follow. The wax ring and bolts make sure the toilet is secure and does not shift during use. A toilet flange is critical!

How long does a typical toilet Flange last?

Up to 30 years. A flange and its wax seal will often last the life of the toilet, 20 or 30 years, without needing to be changed.

What are the signs my toilet flange needs replacing?
