Disconnect Drain Plumbing — Prepare the Work Area
Part of project
How to Replace a Bathtub Waste and Overflow Drain Assembly · Step 1 of 9
In this video
Go to the area beneath the bathtub, such as a basement or crawlspace, to access the drain plumbing. Locate the P-trap and drain assembly connected to the underside of the tub. Using a wrench or by hand if possible, loosen the slip nut that connects the drain assembly to the tub's drain pipe. If the connection is old and seized, you can use a reciprocating saw to cut the pipe. The goal is to completely disconnect the tub from the house's drain system.
Goal: Plumbing
- If the plumbing is old and you plan to replace it anyway, simply cutting it with a saw is often the fastest method.
- Ensure there is no water in the tub or pipes before disconnecting to avoid a mess.

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.
