How to Replace a Bathtub Overflow Drain Gasket · Step 1 of 7
In this video
First, place the new rubber gasket over the drain pipe, ensuring it sits flat against the underside of the bathtub. Next, take a small amount of plumber's putty and roll it into a rope shape. Press this putty rope firmly onto the underside of the new drain's flange. Insert the new drain into the tub's drain hole and screw it clockwise into the drain pipe. Hand-tighten it first, then use the drain removal tool to tighten it securely. Wipe away any excess putty that squeezes out.
Goal: Install the new drain and seal
- The video incorrectly shows the use of caulk. You must use plumber's putty to create a proper, lasting, and removable seal.

FAQs
How difficult is replacing a bathtub overflow gasket, and what's a realistic time commitment for a beginner?
This is considered a beginner-level plumbing DIY project, primarily involving simple disassembly and reassembly. While the estimated time is 2 hours, allow yourself extra time, perhaps 3-4 hours, especially if the old gasket is stubborn or significant cleaning is required, to avoid rushing.
What should I do if my bathtub overflow still leaks after replacing the gasket?
First, ensure the new gasket is properly seated and the overflow cover plate screws are tightened snugly, but not overtightened, which can warp the plate. If the leak persists, carefully inspect the mating surfaces for any remaining debris, cracks, or imperfections on the tub itself or the overflow pipe that could be preventing a complete seal. You might need a thin bead of plumber's putty or silicone sealant around the edges of the gasket if the surface is uneven.
Do I need all the specific tools and materials listed, or are there acceptable alternatives?
The multi-screwdriver is essential for removing and reattaching the overflow plate. While specific brands are listed, any multi-purpose screwdriver with appropriate head sizes will work. For cleaning, an all-purpose cleaner and rags are crucial; the specific brand isn't critical, but a hydrogen peroxide-based cleaner is effective. The utility blanket is mainly for protecting surfaces, which can be substituted with old towels or cardboard.
What's the best way to remove an old, stubborn, or brittle overflow gasket without damaging the tub?
After removing the cover plate, carefully use a small, flat-head screwdriver or a utility knife to gently pry out the old gasket, working slowly around its edges. If it's very brittle, it might break into pieces, which is fine; just ensure all fragments are removed. Take extra care not to scratch the tub's finish or the overflow pipe's surface during removal.
