How to Remove a Corroded Old Bathtub Drain

Use caution by gently removing the drain from the tub to avoid any costly repairs from damaged drain parts.

1. Remove the drain plug. Create your own drain remover with a pair of slip-joint pliers and a thick screwdriver. Slide the pliers' handles down into the drain, past the X-shaped metal arms inside. Place a screwdriver between the handles and use it as a lever to unscrew the drain.

2. Disconnect the drain assembly once the drain is removed. Remove the screws in the overflow coverplate and disconnect the coverplate along with any attached drain plug linkage.

3. Remove the overflow pipe. Unscrew its slip nut (the device that secures the rest of the drain to the pipe), lifting it from the pipe. Stuff an old rag into the waste pipe after the overflow pipe is removed. This will keep sewer odors and gases from entering your home.
