tub drain replacement

Bathtub drains occasionally need to be replaced, and drains with the built-in stoppers are the ones that usually have problems.

These will become harder to use over time and will eventually allow water to leak.

The flange is the part around the drain hole that seals the joint between the tub and the piping below.

If you believe that it is no longer sealing properly and water is entering this area, you should replace and reseal this flange immediately.

The drain flange is replaced by being unscrewed from the bathtub drain shoe. This is a pipe length that is connected to the drain and overflow pipes.

Replacing a drain flange requires removing the old stopper and old flange. Since there are various stopper options, it is crucial to identify the stopper type.

Once the plug is out of the way, the extraction and installation are the same for most types of drain flanges.
