The Complete Guide to Spa jet parts

Spa jet parts are very important on the spa tub

They’re such tiny parts of your spa, yet they’re crucial. Without hot tub jets moving the water around, you’re basically just sitting in a big bathtub, and if you can’t add bubble bath, it’s just no fun. (Note: Please don’t put bubble bath in your hot tub.)

The point is, jets make a spa what it is. If you haven’t given them much thought before, it’s time to get to know them a little better.

How Do Spa jet parts work?

You know they push water into the tub and provide a nice massage when you sit up against them. What you may not know is how.

The jets depend on the movement of water to produce that bubbly effect we love so much. Understanding how hot tub jets work is knowing the basics of hot tub plumbing.

Water exits the hot tub via the suction line; the suction is created by the hot tub pump.

The water flows through the pump into the filter where debris and contaminants are removed.

The filtered water moves into the heater where it passes over the heating element and is heated.

The water enters the return line.

The water moves through the return line to the hot tub jet’s entrance, where the magic happens.

The inner portion of the jet narrows, and then widens again at the exit, which is the part visible in the hot tub shell; picture a sideways hourglass.

Physics happens.

Water and air are both expelled from the jet and into the hot tub.

The process starts over.

Spa jet parts Reduced Water Flow

If you notice the hot tub spa jets pulsate rather than providing a steady flow of water, it’s likely there’s a water flow problem.

First, check the water level in the hot tub. Make sure it is filled to the correct level recommended by the manufacturer. If the water level is too low, air could be finding its way into your system, causing the jets to pulsate.

If the water level isn’t too low, it could be that the filter has become too dirty or clogged, and is impeding water flow. Remove and clean the filter, or replace it if it’s worn out. Put the filter back, turn the system back on, and check the flow.

If it’s neither of those possibilities, you could have a more serious problem. It’s possible you have a blockage in the hot tub lines. Try to locate a blockage. If you can’t find one, it may be that your pump is shot and needs to be replaced.

Spa jet parts keep clean.

Sometimes, when you drain and refill your hot tub, air can get into the plumbing lines. It may become trapped inside the pump, causing it to lock up, thereby preventing it from being able to move water through the system. As a result, there’s little to no pressure coming out of the hot tub jets.

This is fixed by bleeding the air from the pump. Locate the discharge pipe on the pump, and loosen the coupling, but don’t completely remove it. If you remove it, you may not be able to get it back on due to the pressure from the pump.

Turn the pump back on, and listen for the air to be expelled via the discharge pipe. You should hear a hissing sound. Once the air has been removed, you should see a column of water coming from the system. Tighten the coupling, and you’re done.

Also, make sure you keep the plumbing and the spa jets clean to prevent any kind of buildup from impeding air flow.
