• Plumber's putty
• Channel-lock pliers

2. Removing the Old Drain

The first step in installing a new bathtub drain is removing the old one. Here’s how you can do it:

1. Turn off the water supply: Ensure that the water to the bathtub is turned off to avoid any spills or leaks during the process.
2. Remove the stopper: Unscrew or lift the drain stopper (depending on the type) and set it aside.
3. Loosen the drain shoe: Use your adjustable wrench or pliers to loosen the drain shoe. This may be tight, so apply steady pressure until it comes free.
4. Clean the area: Once the old drain is removed, clean the surrounding area to remove any debris, old sealant, or leftover plumber’s putty.

With the old drain removed, you’re ready to install the new one.

3. Installing the New Drain

Now that the old drain is out, you can proceed with installing the new one. Follow these steps for a smooth installation:

1. Apply plumber’s putty: Roll a small amount of plumber’s putty into a rope-like shape and apply it around the edge of the drain flange.
2. Insert the drain flange: Place the drain flange into the drain opening in the bathtub, pressing it down gently to ensure a tight fit.
3. Attach the drain shoe: From underneath the bathtub, attach the drain shoe to the drain flange. Tighten it securely using the channel-lock pliers.

Make sure everything is aligned properly before moving to the next step. Tightening too soon can cause misalignment, leading to leaks.

4. Sealing and Tightening

After you’ve installed the drain, it’s important to ensure a watertight seal:

1. Apply more plumber’s putty: If necessary, apply another thin layer of plumber’s putty around the edges of the drain flange to ensure a good seal.
2. Tighten the drain assembly: Use your adjustable wrench to tighten the drain assembly under the bathtub. Be careful not to over-tighten, as this can cause damage to the drain or the bathtub.

Once everything is tight and sealed, you’re ready to test the drain.

5. Testing the Drain

The final step is to test the new drain to ensure there are no leaks:

1. Turn on the water: Slowly turn the water back on and let it run into the bathtub.
2. Check for leaks: Inspect the drain area closely to ensure there are no leaks. If you notice any leaks, tighten the connections slightly and test again.
3. Check the drainage: Ensure that water flows smoothly down the drain and that it doesn’t back up.

If everything works as expected, congratulations—you’ve successfully installed a new bathtub drain!
