Jetted Bathtub Plumbing Explained

If you are thinking of installing a jetted bathtub inside your home, you may want to consider hiring a professional plumber and electrician to perform the installation for you.

In fact, many cities and municipalities require that a licensed and professional plumber do the plumbing for a jacuzzi, jetted tub, or spa that is placed inside the home.

On the other hand, if you are planning on installing a jetted bat on a deck or patio, you might consider doing the work yourself and saving some money. Installing a jetted bat tub is not the easiest DIY project, and does require a bit of work and planning.

However, it is a task that many DIY enthusiasts can successfully complete. Still, there are several things about jetted bathtub plumbing that you should understand before undertaking such a project.

Getting Water to Your Jetted Bathtub

Plumbing for a water supply to a jetted tub is not so dissimilar to that used for a regular bathtub or shower. However, there are a couple of significant differences.

For example, while water inlet pipes for a regular bathtub or shower run directly to the faucets of the tub, a jetted bathtub's water supply must also pass through a pump.

The pump used in a jacuzzi or jetted tub provides the force and pressure needed to create the swirling action and bubbles that these types of tubs are known for. So, the water inlet flow starts at the main water pipe for your home and is then directed to the water inlet hose for the jetted tub pump.

The water is then forced into the bathtub through a faucet and pipes which are connected to jet nozzles which helped to create the force for the swirling action.

Another significant difference in the way jetted bathtubs are plumbed, as opposed to regular bathtubs or showers, is the way the union fittings are made.

With regular tubs and showers, the water inlet connections are usually made with plumber's pipe dope and are considered to be semi-permanent or permanent water connections. However, with a jetted tub, and the union fittings are usually made with a PVC type compression fitting that is tightened by hand.

The fitting is designed to be adjusted occasionally and is made in a way that makes it easy to replace.

How Jetted Bathtubs Are Drained

When it comes to installing the plumbing for the drainage of a jetted bathtub, it is not too different from that of a regular bathtub. Like a regular tub or shower, installing drain piping for a jetted tub will involve creating a hole in the floor and subflooring; connecting P-trap; and tying into the main water vent line for your home.

Planning for Leaks

Another thing to consider when installing the plumbing for a jetted tub is that there are many more points in a jetted tub that can leak than with a regular tub or shower. Therefore, great care must be exercised in creating joints that are properly fitted and sealed.

Installing a jetted tub is a lot of work, and having to tear one out to repair leaky pipe joints underneath the tub is even more work. So, before attempting to install a jetted bathtub, you should become very familiar with properly joining PVC pipe and using proper pipe fitting methods to tie into your home's main water supply line.
