We recently moved into a home that has a Catalina Coronado model spa. I believe a 2004 model but I can't remember for sure.
It was missing almost all of the jet inserts so when I drained and cleaned the spa out I replaced them.
After refilling I had no jet pressure at all. Researching the net it seemed I had an airlock issue so I followed all of the advice here on clearing it.
I thought I had it fixed as I saw jets start to spin and could feel water coming through them, but it never got above a weak little stream. all of them have water flow, but it is really weak.
A few of the jets will throw out a couple of small bubble streams now and then but nothing more. The spinning type jets turn really slowly. Nothing like I have always seen them do in the past.
If I open up the floor jet it is really strong and what I would expect. If I close off all of the jets except one it is barely pushing any harder. Definitely not enough force to be considered acceptable.
The pump is a 2 speed, and both speeds and off can all be distinctly heard.
The blower doesn't help anything with the pressure, just makes big bubbles.
If I turn on the waterfall it has good pressure and is able to arc out into the middle of the spa.
Misters work fine as well.
I'm kind of at a loss. Is it possible I still have an airlock somehow? I've loosened the fitting above the pump several times. Initially I could hear a lot of air coming out, but now it is only water when I try it.
I'll give anything a try if you have suggestions.
