How to Plumb a Jetted Bathtub Part 3 How to Plumb a Jetted Bathtub Part 3

What You'll Need
Teflon plumber's tape
Plumber's putty
Apair of channel locks or adjustable crescent wrench
Flexible water supply lines
Bucket of water
Water faucets for your jetted tub

In Part 2 of this series on how to plumb a jetted bathtub, you learned how to install the overflow pipe assembly, cut the tail piece so that it properly fits the overflow pipe assembly and install the drain flange and cover plate on your jetted bathtub. In Part 3, you will learn how to connect the overflow assembly to your P-trap, test the jetted tub drain system and then learn connect the water supply valves for the water faucets and the faucets themselves. Follow the simple steps below.

Step 1 - Connect Over Flow Assembly to P-Trap

Wrap Teflon plumbers tape around the threaded end of the P-trap. Then, position the P-trap so that it is inserted into the tail piece pipe of the other overflow pipe assembly and tighten the compression nut.

Once you have the compression nut hand tight, use a crescent wrench or a pair of channel locks to turn the compression nut an additional ¼ turn. Remember not to tighten the P-trap compression nut too much as it will cause the P-trap and tailpiece to leak when water overflows into that part of the drain.

Step 2 - Test the Drain on the Jetted Tub

In order to test the drain system in your new jetted tub, you'll need to introduce water to find out if there are any leaks. So, fill a bucket with water and simply pour it down the drain of the Jacuzzi. Also try to pour some water into the overflow flange of the jetted tub. This will help you make sure that the P-trap or tailpiece pipe is not leaking in the overflow pipe assembly.

Step 3 - Connect Water Supply Lines for Faucets

Take the faucet water supply lines and attach them to the connections on the intermediate water supply risers or the shutoff valve that is connected to the water inlet pipe. Be sure to use Teflon tape on all threaded connections. If you have 2 water lines running into your jetted bathtub, repeat the process for the second water line.

Step 4 - Install Water Faucets in the Jetted Tub

Insert the faucets into the holes on the jet tub that have been created to hold the faucet fixtures. Then, create a fairly thick bead of plumber's putty that will be used to help hold the faucet in place and keep it from leaking. Make sure the faucet is connected to the water supply line and that you have used plumber's tape on the fittings. Once you have the faucet in the hole, make sure that the rubber gaskets on the bottom of the faucet are in place as well as you use the screws to secure the front and rear pieces of the faucet.

Once the faucet is installed, spin the cover plate and clockwise to cover the opening. Then, you need only to install the handles on the faucets.
