How to Replace a Bathtub Overflow Drain Gasket · Step 3 of 6
In this video
First, prepare the new drain assembly by applying a sealant. Take a small amount of plumber's putty, warm it in your hands, and roll it into a thin rope. Press this rope of putty firmly onto the underside of the new drain flange. Next, clean the drain opening in the tub to remove any old residue. Carefully hand-thread the new drain into the pipe to avoid cross-threading. Once started, use the barbell tub tool to tighten it down. The plumber's putty will create a watertight seal as it's compressed.
Goal: Install Drain
- Hand-thread the drain first to prevent damaging the threads.

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.
