Toilet Flange Below Level Floor

Give some thought to the height of the finished floor and you should be able to work out how high it needs to be.

Toilet flange below level floor.

A sign that the wax ring was not sealing the toilet from sewer gases or preventing water escaping from under the base of the toilet. The perfect height for the toilet flange is to be the same level as the finished floor. Purchase a new one if the previous flange is too low purchase one that is designed to sit on the finished floor and provide the optimum toilet flange height. A toilet drain flange can sit above or below the finished floor level.

In a typical toilet installation the floor flange that sits inside the drain opening below the toilet should be positioned so that its bottom surface rests flush against the finished floor or no more than 1 4 inch above or below the floor. If your bathroom was built like this then you ll need the set rite toilet flange extender system or a similar system to properly raise the height of your flange. Flange extenders are commonly sold in 1 4 inch and 1 2 inch sizes to raise the height of the existing flange 1 4 or 1 2 inch. As a result the flange is sits below the floor and is screwed into the subfloor.

I believe products in this category are designed to replace the use of wax rings only although fernco advertises that it can handle toilet flanges that are up to 3 4 lower than the floor surface. The installation process is the same for a tile floor a hardwood or carpeted bathroom floor. Large bolts thread up through. If it s a little too low then this probably won t be an issue.

Most extenders come with long bolts which may be necessary if the flange is below the floor level. When the toilet was removed the toilet wax ring was still in its original shape. The optimum toilet flange height is approximately inch above the floor to achieve the best seal and overall fit. This can be difficult as you probably haven t laid your floor at the moment.

If your current flange is broke then you ll also need a new one. Here you can see the results of a toilet having been installed on a toilet flange that is below the floor level.
