Install Drain Tailpiece on Tub — Dry-Fit the New Assembly
Part of project
How to Replace a Bathtub Waste and Overflow Drain Assembly · Step 6 of 9
In this video
With the tub on its side, install the drain and tailpiece assembly. This typically involves applying a sealant like plumber's putty under the drain flange inside the tub and then threading the brass tailpiece on from the outside. Tighten it securely with pliers. Before setting the tub, apply a lubricant such as silicone grease or dish soap to the O-rings on the end of the tailpiece. This is a critical step to ensure it slides smoothly and seals properly within the floor drain's gasket.
Goal: Attach the drain hardware to the bathtub
- Do not skip lubricating the O-rings. A dry installation can damage the gasket and cause leaks.

- Channel-lock Pliers (Tool Type: Plumbing Tools) · optional — Tightening the nut that secures the tailpiece to the bathtub drain.

FAQs
How long should I expect this bathtub drain replacement project to take, especially if I'm a beginner?
For a beginner, plan to dedicate 3-5 hours for this project, including preparation and clean-up. Accessing the old drain and ensuring proper sealing of the new one can take time, so don't rush the process to avoid potential leaks later on.
What are the most common mistakes beginners make that lead to leaks after installing a new bathtub waste and overflow?
The primary cause of leaks is inadequate sealing. Ensure you apply a generous amount of plumber's putty (like Oatey 14 oz. Plumber's Putty) under the drain flange and correctly position and tighten the overflow gasket. Always perform a thorough leak test before re-enclosing any access panels.
Do I need special tools to remove a stuck or corroded old drain flange, or will standard tools suffice?
While a screwdriver and tongue-and-groove pliers (Channellock 430/440) are often sufficient, a severely corroded flange might require a specialized drain wrench or carefully using a hacksaw (Husky 10 in. Close Quarters Hacksaw) to cut the crossbars. Avoid excessive force to prevent damaging the tub's finish.
What are the most important safety precautions I should take during this bathtub drain replacement?
Always turn off the water supply to the bathtub before starting to prevent accidental flooding. Wear safety glasses to protect your eyes from debris, and ensure good ventilation if using plumber's putty or sealants. A drop cloth (TRIMACO Stay Put Canvas Plus) will protect your bathroom floor and catch any spills.
