Remove the Drain Cover

To begin, remove the metal cover from the drain. On some drains, you might find that you can simply flip the cover off with your flat head screwdriver. On other drains, you may need to remove the screws. If this is the case, store the screws in a safe location so that you can put them back on later.

Remove the Compression Gasket

Use the pliers to remove the compression gasket. Clip the pliers one on either side of the gasket, turn it counterclockwise until it comes loose, then pinch the gasket on the other side with the pliers, and pull it out of drain.

You can remove the large compression nut from the drain with the groove pliers.

Remove the Shower Drain Body

This is the fun part. Use the hacksaw to cut through the body of the drain with two vertical cuts. Now cut off the drain flange with your hacksaw. Cut the two vertical cuts about an inch apart.

 When cutting the drain flange there’s two parts you must be careful not to cut through:

  • The shower pad
  • Pipe riser.

Clean the drain opening with your cleaning brush, or an old toothbrush. This removes any debris that could inhibit the installation of the new gasket.

Install New Compression Gasket

Slide the new gasket into place. Make sure that it sits on the center of the rim of the drain body. Use your fingers to spread the outer surface of the strainer body with plumber’s putty. Make sure that there is plenty of putty under the rim of the drain.
