DIY steps
- Shut off the water supply to the bathtub by locating the shut-off valves and turning them clockwise. Put on your rubber gloves and safety goggles to protect yourself from any potential mess. Place a bucket under the overflow drain to catch any water that may spill out during the repair.
- Remove the overflow plate by unscrewing the screws that hold it in place. Gently pull the plate away from the wall, taking care not to damage the surrounding area. If the plate is stuck, use a flathead screwdriver to pry it loose.
- Disconnect the old linkage from the overflow drain by releasing the clip or nut that holds it in place. Use pliers to loosen any corroded or stuck parts. Remove the old linkage from the drain and set it aside.
- Install the new linkage by attaching it to the overflow drain and securing it with the clip or nut. Make sure it is properly seated and aligned with the drain. Do not apply plumber's putty to the linkage; the overflow plate gasket, not moving linkage parts, provides the water seal.
- Reattach the overflow plate by screwing it back into place. Make sure it's securely fastened to the wall to prevent any leaks. Test the linkage by lifting the overflow plate and checking that it's properly connected to the drain.
- Clean up any mess or spills from the repair. Dispose of any old or broken parts, and wash your hands thoroughly with soap and water.
- Test the bathtub drain to ensure it's working properly and the overflow linkage is functioning as expected.
