Toilet Flange Below Level Floor

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.

Toilet flange below level floor. Large bolts thread up through. If it s a little too low then this probably won t be an issue. The perfect height for the toilet flange is to be the same level as the finished floor. 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.

Most extenders come with long bolts which may be necessary if the flange is below the floor level. This can be difficult as you probably haven t laid your floor at the moment. Give some thought to the height of the finished floor and you should be able to work out how high it needs to be. As a result the flange is sits below the floor and is screwed into the subfloor.

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. When the toilet was removed the toilet wax ring was still in its original shape. Here you can see the results of a toilet having been installed on a toilet flange that is below the floor level. To get the necessary clearance from the floor you can add a toilet flange extender which is quick and easy to install.

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. 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. The optimum toilet flange height is approximately inch above the floor to achieve the best seal and overall fit. This ensures that the flange makes a watertight seal against the wax ring that fits between the drain opening and drain outlet horn on the underside of the toilet.

Toilet flange extenders are constructed with either soft or hard pvc providing solid pathway from the bowl horn to the toilet flange on the floor. A toilet drain flange can sit above or below the finished floor level.
