Reasons for Replacing a Bathtub Drain

Several factors may necessitate replacing a bathtub drain:

Clogs and Backup: Persistent clogs, despite using drain cleaners, indicate a problem with the drainpipe or assembly.
Leaks: Water leaking from beneath the bathtub, especially after use, signals a compromised drain seal or loose connection.

Channel locks or pliers
Rag or towel
Bucket or basin

Step-by-Step Replace Bathtub Drain

Follow these steps to replace the bathtub drain efficiently:

Turn Off Water Supply: Locate the water supply valves for the bathtub and turn them off to avoid flooding.
Remove Existing Drain: Use an adjustable wrench to loosen and remove the overflow plate and drain stopper. Carefully pull out the drain assembly.
Clean the Flange: Using a rag or towel, thoroughly clean the bathtub flange where the drain assembly sits to ensure a proper seal.
Apply Plumber's Putty: Apply a generous bead of plumber's putty or silicone sealant around the base of the new drain assembly.
Insert New Drain: Carefully insert the new drain assembly into the flange and hand-tighten it. Avoid overtightening.
Install Overflow Plate: Place the overflow plate over the drain and secure it with screws using a screwdriver.
Install Drain Stopper: Insert the drain stopper into the new drain assembly and press it into place.
Turn on Water Supply: Turn on the water supply valves and check for any leaks around the drain. Tighten the drain assembly further if necessary.
