I had to complete a couple of toilet flange installs on a concrete floor.
Toilet flange set flush to floor or on top.
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.
Set the toilet straight down on top of the flange.
Toilets are sealed to the floor flange with a wax ring but the height of the flange and the tightness of the flange bolts.
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.
As a result the toilet may wobble or leak at the base.
A toilet flange sometimes referred to as a closet flange is the piece of the toilet upon which the toilet rests.
You also want to make sure the toilet sits level and does not rock on the floor as this can compromise the seal.
Closet flange installation 2 flush with the floor.
Cast iron floor closet flange is designed as a replacement flange for broken cast iron flanges.
Though above floor installation is considered the right way to fit a flange some swear by attaching it level with the floor.
Serves the dual purpose of supporting the toilet and connection it to not only the floor but also the plumbing.
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.
It has to sit evenly on top of the finished floor.
The reason being is because the toilet recesses into the flange when fully installed but when the flange sits even or below the floor the toilet can t properly recess into the flange.
Continuing reading for important advice on setting a toilet flange to the correct height.
The oatey twist and set 4 in.
This is very important.
