Hi,

I am working on getting an older spa going. It has Wateway jets in it. I know some of the standard jet gaskets need replacing. The spa also has some of the smaller cluster jets in it, including some of the "Front access Cluster Pulsator" jets. Would the gaskets need replacing on these as well, or are these jets different. I was reading on some of the other threads here about if the jet gasket is bad, water can go up into the air supply system for the jets from the jet body. Is that a possibility with these cluster jets, or are they different and possibly not tied into the air supply?

Cluster jets... you should not have that problem with as they are not adjustable.

Mini jets on the other hand are adjustable and have two separate o-rings on the diffuser. Unscrew/pull out the front of the jets and you'll see...
