Toilet flange set flush to floor or on top.

Though above floor installation is considered the right way to fit a flange some swear by attaching it level with the floor. As a result the toilet may wobble or leak at the base. It has to sit evenly on top of the finished floor. When you are replacing a toilet or resetting an existing toilet after a repair there are a few key things to check to ensure a good seal and prevent leaks.

Set the toilet straight down on top of the flange. Set your toilet flange into position on top of the tile with the back holes lined up parallel to the wall behind and the two slots parallel to the two walls on each side of the toilet. This is very important. A toilet flange sometimes referred to as a closet flange is the piece of the toilet upon which the toilet rests.

Continuing reading for important advice on setting a toilet flange to the correct height. Toilets are sealed to the floor flange with a wax ring but the height of the flange and the tightness of the flange bolts. You also want to make sure the toilet sits level and does not rock on the floor as this can compromise the seal. The flange simply installs into cast iron piping and the tapered design allows the rubber gasket to compress on all types of cast iron piping.

I had to complete a couple of toilet flange installs on a concrete floor. Once the toilet is resting on the flange press down firmly near the back of the bowl rim to deform the wax ring and seal the connection. The process is generally the same but the flange is secured down before the floor is finished. The oatey twist and set 4 in.

Line up the holes in the toilet base with the 2 bolts that protrude from the flange.
