What are Gunite Jet Bodies?

If you have seen the awesome YouTube videos that show shotcrete or Gunite concrete being sprayed into a wireframe to create a pool, then you will have seen these parts before. It takes some highly skilled labourers then skim it flat to form the surface of the pool. This is not the style of Hot Tub we can build in our own back yards. However, If you are thinking about building a concrete hot tub or cinder block hot hot, even a brick hot tub, you are going to need some jets.

The jets are going to need to get through the walls and the Gunite bodies are exactly how this happens.

How Do Gunite Jet Bodies Work?

The two sets of pipework that you can see carry water (in the larger 2″ pipe at the bottom” and air (in the smaller 1.5″ pipe on the top) into the Gunite Bodies. This water and air then mixes in the Gunite get body and in the process forms a much stronger powered jet that then flows back into the Hot Tub. You can really feel the difference if you turn your pump onto full power without the air blower running. Switch on the air blower, and the power of the jet dramatically increases.

The water and the air lines are separate but as you might expect, it is possible when the blower is not running for water to get into the air pipework. This is not a problem as long as you have a non-return valve fitted to your blower. The last thing you want is a blower (which is really like a hair dryer on steroids) full of water. Why? As you might expect your electricity will be tripping for sure! Water and electricity do not mix.

Decision Time.

Before you assemble the jet body, you need to decide if you are going to connect the external air and water pipes first. Or, are you going to assemble the jet bodies but not fix them in place until the air and water pipes have been connected. This is really a decision you will have to make on site and depends on how close the jets are to each other. The closer they are, the harder it is to get even the “flexible” pipe into the holes on either side of the jet bodies; they can be very tight. It can be easier to assemble the exterior pipework first with the jet bodies then push them through the holes. This was how I did it. The decision is up to you.
