How To Replace Kohler Bathtub Drain

How to Replace a Kohler Bathtub Drain

A bathtub drain is a crucial component of any bathroom, allowing water to flow away after a bath. Over time, bathtub drains can become clogged, lose their seal, or simply wear out. When this happens, it's essential to replace the drain to maintain proper bathroom functionality and prevent water damage. This article will guide you through the process of replacing a Kohler bathtub drain, providing step-by-step instructions for a successful replacement.

Step 1: Gather Necessary Tools and Materials

Before starting the replacement process, ensure you have all the necessary tools and materials. These include:

A new Kohler bathtub drain assembly
Adjustable wrench
Channel-lock pliers
Screwdriver
Plumber's putty
Teflon tape
Bucket or container to catch water
Gloves
Safety glasses

It is recommended to purchase a new drain assembly that is compatible with your existing bathtub and plumbing system. Consult the Kohler website or a local plumbing supply store for compatible options.

Step 2: Shut Off Water Supply and Drain Existing Water

Before disassembling the old drain, turn off the water supply to the bathtub. This is usually done by a shut-off valve located near the bathtub. Once the water supply is off, drain any remaining water from the tub by using a bucket or container to collect it. This will prevent water from spilling when the drain is removed.

Step 3: Remove Existing Drain Assembly

The existing bathtub drain assembly typically consists of a strainer, a tailpiece, and a drain body. To remove it, follow these steps:

Locate the nut that secures the strainer to the drain body. This nut is usually located under the bathtub, accessible through a small access panel.
Use an adjustable wrench to loosen and remove the nut, holding the strainer in place with channel-lock pliers to prevent it from turning.
Once the strainer is removed, carefully remove the tailpiece by loosening the nut that connects it to the drain body. Use a wrench to turn the nut counterclockwise.
Finally, remove the drain body itself by loosening and removing the nut that secures it to the bathtub. This nut is usually located under the bathtub and can be accessed through a small opening.

Step 4: Prepare New Drain Assembly

Before installing the new drain assembly, it's crucial to apply Teflon tape to the threads of the tailpiece and drain body. This will help create a watertight seal and prevent leaks. Wrap the tape counterclockwise around the threads, ensuring that each layer overlaps slightly.

Step 5: Install New Drain Assembly

With the new drain assembly prepared, start installing it by following these steps:

Insert the new drain body into the bathtub and secure it with the nut. Tighten the nut using a wrench, ensuring it's secure but not overtightened.
Attach the tailpiece to the drain body by threading the tailpiece into the drain body and tightening the nut using a wrench.
Position the strainer over the drain body and secure it with the nut. Tighten the nut using an adjustable wrench and channel-lock pliers.
Apply plumber's putty around the base of the strainer to create a watertight seal against the bathtub surface.
Double-check all connections for tightness and leaks before turning the water supply back on.

Step 6: Test New Drain Assembly

After reconnecting the water supply, run the bathtub faucet and check for leaks. If no leaks are present, test the drain functionality by filling the tub with water and allowing it to drain. Ensure the drain operates smoothly and drains water efficiently.

By following these steps, you can successfully replace a Kohler bathtub drain and restore proper bathroom functionality. Remember to consult the manufacturer's instructions for your specific drain assembly and take necessary safety precautions throughout the process.
