The closet flange is the mechanical connection between the toilet drain and your home’s drainage system. If this connection is broken or improperly fitted, it can lead to sewer gas and water leaks.
A toilet flange also acts as a stabilizing floor mount for your toilet. The flange is typically made from a PVC, copper, steel, or brass pipe, and is paired with a metal or plastic ring that bolts it to the bathroom floor. The flange is then sealed to the drain of your toilet with a wax ring to prevent leaks.
Toilet flanges should either be three or four inches in diameter, depending on the size of the drainpipe.
The flange should fit the pipe either by sliding over it or fitting snugly inside of it. The length of the pipe should be adjusted according to the thickness of your floor finishing. Using a flange of the wrong diameter or an improper height can create installation issues and leaks.

Common Issues That Lead to Toilet Flange Repair
If you notice any of the signs of toilet flange damage, one of the following issues could be to blame. We recommend toilet flange repair services to stop the damage from worsening:
- A flange that isn’t flush with finished flooring: If you’re planning to redo your bathroom flooring, don’t forget about the flange! Toilet flanges perform best when they are secured tight and flush with finished flooring. Securing the flange is an important step in refurbishing a bathroom floor; if skipped, it can lead to leaks. You may have to adjust the toilet flange height, either by cutting the pipe or using a flange extender, to ensure that it is at the proper level.
- A blocked or clogged flange: Toilet backups can be caused by clogged flanges. If your flange is clogged or clogs frequently, it may require professional repair.
- Cracked or broken flange: If you notice a lot of water pooling at the base of your toilet and find that your flange is cracked or broken, it’s time for a toilet flange replacement. Make sure to properly measure your drainpipe and drain to ensure that you choose a replacement flange kit that is the right size.
- Loose or broken wax rings: Another common reason for pooling water is a loose or damaged wax ring, which breaks the waterproof seal. Wax ring replacements should always be carried out by professionals.
