How do I Install an Inline Bathtub Plug Drain?

Install a new bathtub drain plug for your home.

If you have a bathtub drain plug that does not hold the water in the tub, you may want to consider replacing the entire drain with a new one. Contemporary bathtub drains are able to be installed by the homeowner, and sturdy enough for years of use. You can replace the drain system in your bathtub, allowing you to have a new drain plug that will keep the water in the tub during your baths.

Things You'll Need

• PVC drain and plug kit
• Plumber's putty
• Screwdriver
• Measuring tape
• PVC glue
• Hacksaw
• Screwdrivers
• Adjustable wrench

Instructions

1. Remove the current bathtub drain. Open the access panel behind your bathtub and cut off the existing drain pipe using a hacksaw, cutting just below the drain hole in the tub. Use an adjustable wrench to remove the rest of the fittings. In some homes, you may need to cut a hole in the ceiling directly below the tub drain so that you can access underneath. Cutting a hole in the ceiling is only for ease of use. If you have a bathtub on a slab floor with no basement, you can get underneath by just using the access panel, but it will give you a little less room to work and move around.

2. "Dry fit" the new drain pieces together, in place, to make sure they fit. Trim any sections that may not be to the proper length, using a hacksaw or PVC cutter.

3. Install the drain. Thread the drain into the drain hole of the tub, tightening it down with a pipe wrench. The underside of the drain outlet, where the drain meets the tub, will need plumber's putty to keep it from leaking. Install the rubber gasket on top of the shoe elbow that threads underneath the tub.

4. Install the plug into the top of the drain. Add a bucket of water to the tub and check for leaks, tightening as necessary.

5. Install the overflow cover at the top of the tub, just under the on/off knobs.

6. Install PVC pipe between the overflow, the drain, and the drain pipe. Use purple PVC cleaner to clean each joint and fitting, then apply PVC cement to each joint (one at a time). Press the fittings all the way together and then turn them a quarter-turn to allow the glue to seat completely. Allow the project to dry for 24 hours before adding water.

7. Test the whole system. Turn the water on and allow the water to flow down the drain. Using a flashlight, check every joint and make sure that there are no leaks.
