Tech Tip:

Note that the Cloud Burst type of jet is not an easy replacement.

The jet internals come out,  but if you are trying to replace the whole jet then the nut on the underside of the old jet has to be taken out and the hose cut and then to replaced.

The jet goes in and you have a gasket (included) in the front of the spa. On the under side you would want to silicone to seal from the backside of the jet.
