Now let’s discuss Toilet flange extender –

A toilet flange extender fits over the existing flange to raise the drain connection to the surrounding flooring. Plastic flanges typically cannot be remove because they’re the glue to the drain pipe. So in such cases, we’d like to use toilet flange extenders, which are made from plastic rings that are available in various thicknesses. Most extenders are secure by fastening them to the subfloor with screws driven through the holes within the old flange.

The materials require for installing a toilet flange extender are the same as that of regular toilet flange. Only one additional piece of equipment need is silicone caulk. Sometimes toilet flange extenders have rubber gaskets that will not require caulk for sealing the space between the floor and the extender.

Now while installing the toilet flange extender, the procedure remains the same as that of replacing the toilet flange. One minor change is that as the flange is the glue to the drainpipe, the extender is to be apply above the existing one. Apply a liberal amount of silicone caulk on the bottom of the flange extender. Place the extender on the top of the old flange, including spacers as require. Place the screw holes in the extender into the old extender. Tighten up the screws to the extender with the floor.

Since the extenders are not replaceable, one needs to check the durability of them.

What kind of toilet flange extenders should one buy that will last for a longer time? 

An extender that has a stainless steel ring will last longer than that of plastic material as they are more prone to damages. It is essential to buy superior quality flange material because the toilet being the moist area is in constant contact with the toilet waste, which makes it more prone to damage.

How often should one change the Toilet Flange?

A wax seal material is use between the toilet, and the flange helps to retain the water from leaking as it passes from the toilet to the sewage pipe. It also seals the awful odors. A wax seal will often last up to 20 to 30 years without needing to be change.
