In this video
Use your finger to wipe away the excess plumber's putty that has squeezed out around the flange. Use a damp rag for a final cleanup. To test the repair, close the drain stopper and fill the tub with a few inches of water. Let it sit for a while and check to see if the water level drops or if there is any sign of leaking underneath. If the water holds, the problem is fixed.

FAQs
How difficult is it to replace a bathtub overflow drain gasket, and how long should it take for a beginner?
Replacing a bathtub overflow gasket is considered a beginner-level DIY plumbing project. Most individuals can complete it within 30-60 minutes, but budgeting up to 2 hours, especially if cleaning is extensive or you're unfamiliar with the process, is a good idea. The main costs will be for a new gasket and potentially a new overflow plate if yours is corroded.
What are the essential tools and materials required for this project, beyond the new gasket itself?
Beyond the new overflow gasket, you'll primarily need a multi-bit screwdriver (like the Husky 19-in-1) to remove the cover plate screws. A scraper or utility knife is helpful for removing old caulk or debris, along with a rag and mild detergent for cleaning the tub surface. Water is essential for testing the new seal.
What are common mistakes to avoid when replacing the gasket, and how can I ensure a watertight seal?
A common mistake is not thoroughly cleaning the tub surface where the gasket sits, leaving old caulk or debris that prevents a good seal. Another is overtightening the screws, which can warp the plate or gasket. Ensure surfaces are spotless, then tighten screws until snug, followed by a slight quarter-turn, to avoid creating new leaks.
Should I use silicone caulk or plumber's putty in addition to the new rubber gasket?
While the gasket itself is designed to create a seal, applying a thin bead of plumber's putty or silicone caulk (approved for wet areas) around the back edge of the overflow plate, where it meets the tub, can provide an extra layer of leak protection. This is an optional but recommended step for added security. Just ensure it's a quality, durable sealant.
