How To Properly Replace a Tub Drain
You’re staring at a slow-draining bathtub that’s become more of a frustration than a relaxation spa. When your tub won’t clear properly, you might wonder, “How do you replace the drain in a bathtub?” Plumbers in Milpitas, CA, often encounter homeowners facing this exact dilemma.
In this guide, Superior Plumbing will explain the bathtub discharge replacement process with step-by-step instructions.
Identify Your Bathtub Discharge Port
Before you begin the tub discharge removal, you must identify which type of unit stopper you have. Different tub outlet assemblies require specific removal techniques for successful replacement.
Common types of drain stoppers include:
- Toe-touches with spring-loaded mechanisms
- Push-pulls with simple knob controls
- Lift-and-turn systems requiring clockwise rotation
- Trip-levers controlled by overflow levers
- Pop-ups with spring-activated sealing
Each type connects differently to your residential drainage system, so proper identification ensures you use the correct removal method.
Remove the Existing Plug Stopper
Start your drain replacement project by setting the outlet to its open position. For most stopper types, you’ll twist counterclockwise to unscrew the component from the outlet opening.
Toe-touch and push-pull stoppers typically unscrew by hand with counterclockwise rotation. Lift-and-turn stoppers may require removing a set screw beneath the knob before unscrewing the entire assembly. Trip-lever stoppers need the faceplate removed from the overflow drain, allowing you to pull the entire mechanism through the overflow opening.
Remove the Drain Basket
Now you’ve removed your old stopper, but how do you replace the drain in a bathtub? Next, you need to remove the debris basket itself. This step requires either a wrench or locking pliers for better grip.
Insert your wrench into the basket and turn counterclockwise to unscrew it. If using locking pliers, clamp them onto the center crossbar and twist counterclockwise while maintaining steady pressure. The basket features deep threads that require patience during removal.
Use a hairdryer to soften the existing plumber’s putty seal, making removal easier and preventing damage to surrounding surfaces.
Install the New Drain Assembly
Clean the outlet opening thoroughly with bathroom cleaner before installing your replacement drain assembly. Roll fresh plumber’s putty into a pencil-thick log and wrap it around the new drain flange lip for a watertight seal.
Thread the new basket by hand, then tighten securely with your tub drain wrench. Finally, install your chosen stopper according to the manufacturer’s instructions.
Test Your Installation
Close the drain and partially fill the tub with water to test for leaks. Mark the water line with painter’s tape and check after one hour to ensure the water level remains constant, confirming your installation success.
