If you're installing a jetted bathtub in your home, you can save a lot of money by doing the plumbing yourself. Plumbing an old Jacuzzi or jetted bathtub is not as difficult as you may think. Just follow the simple steps below.

Step 1 - Purchase Materials

Visit your local home improvement store or a plumbing supply store and purchase all of the fittings and connectors you will need to plumb your new jetted bathtub. Also make sure to pick up some plumber's Teflon tape as well.

Step 2 - Turn Off Main Water Supply

Before you get started, you should go outside and locate the main shutoff valve for your home's water supply. Then, tighten the valve by turning it clockwise to shut off the water. This will help you avoid accidents while you're working on the plumbing for your new Jacuzzi.

Step 3 - Connect P-Trap to Drain Line

First, you'll need to connect the new P-trap to the drain line of your jet tub. In order to do this, take some plumber's Teflon tape and wrap it around the threaded ends of the P-trap that will be connected to the drain on your new jet tub and outflow pipe. Then, slide the gasket that is located at the top part of the P-trap onto the drain of the jet tub. Next, place the other end on the outflow pipe that was used in your old bath tub.

kFinally, hand tighten the compression nuts on both ends. Then, use a pipe wrench or adjustable crescent wrench to tighten the compression nut ¼-turn past hand tight.

Step 4 - Install Water Supply Risers

The water supply risers are the flexible hoses that are used to deliver hot and cold water to your new Jacuzzi tub. In order to connect them, first wrap Teflon tape around the threaded connectors on the jet tub. Then, twist the locking compression nuts until they are hand tight on the fitting connected to the jet tub. Do this for the other water line as well.

Once you have both water supply riders connected to the jet tub, use a crescent wrench to tighten the compression nuts until you can no longer loosen them with your hand. However, make sure not to tighten them too much or you could damage the supply riser lines or the fitting on the jet tub.

Step 5 - Install Shut Off Valves

Take plumber's Teflon tape and wrap it around the threaded end of the shutoff valve. Then, twist the valve clockwise into the water supply pipe. Do this for the other water pipe as well. Then, use a crescent wrench to tighten the water shutoff valves and make sure that the fitting that will be attached to the water supply riser is aligned straight up and down in a vertical position.

Step 6 - Connect Water Supply Risers to Shut Off Valves

Wrap Teflon tape around the connection fitting on top of the shut off valve. Then, twist the compression nut from the water supply riser onto the connection fitting on the shutoff valve. Use a crescent wrench to tighten the compression nut slightly past hand tight.
