How to Replace a Bathtub Drain Flange
The drain flange is the collar that surrounds the drain opening in your tub. These are mostly made out of metal, although PVC is also becoming a popular choice. Because they are exposed to so much water, sometimes these flanges can rust or start to break. Replacing a bathtub drain flange isn't as difficult as it looks, especially if you either purchase or rent a bathtub drain removal tool. These devices, sometimes called "drain keys", can make easy work of even the toughest bathtub drain flange.
- Spray the flange area with penetrating lubricant. Allow this to soak in according to the manufacturer's instructions.
- Insert the bathtub flange tool into the flange. Align the tines on the end of the tool so that they grip the supports on the inside of the flange.
- Turn the flange removal tool counterclockwise until the flange starts to unscrew.
- Turn the new flange upside down. Insert the silicone caulk into the caulk gun. Trim off the end at the 1/4-inch mark with scissors. Apply a bead of caulk to the underside of the flange.
- Insert the flange into the drain opening right side up. Tighten with the flange tool. Allow the caulk time to cure according to the manufacturer's instructions.
