My Spa, which I dont know what model it is see this post: http://www.spaforums.com/viewtopic.php?t=3314 anyway the spa is blowing air out of some of the jet venturi style. THe tub has no holes in the shell so it is the venturi out of the jet. I am not getting air out of all of the vents. I am also getting air out of the air vents on the top of the shell. I would think these vent are to suck air into the pump and then into the jets, am I wrong???? How do I make the jets all fire, would a muriatic acid rinse do the trick, or is that only for heater problems. Thanks

So you're saying that your spa has a separate air blower, and when you turn it on, the air from the air blower is coming out the JETS right?

If so, then that's called 'turbo air'. Kind of a worthless feature imo.

What 'vents' are you talking about?

Those are air control knobs/valves. Not vents.

What it sounds like you have is a spa that is plumbed for turbo air and the valves/plumbing system is not operating correctly.

You may want to identify all of the blower plumbing, cut it out, and make it work for air action only (using the air knobs) based on the natural suction from the jets.

Turbo-Air (boosted) jets are more trouble than they're worth and provide little to no benefit.

And please don't put any acid in your tub.

ok, I wont do the muriatic acid rinse, the jets do have a turbo air feature, but it is not hooked up. the turbo button is disconnected. The air comes out of smaller bublers and it comes out of the "chair jets" but it also comes out of the screw caps located on the top of the shell as well, my understanding of these screw caps on the top of the shell is that they are for suction, I have air blowing out these, first water then when line is empty, it blows air. I do get some air action in the water, but it does not come from all chairs, I have some chairs that work and some do not. I cant see any vavles that are closed or anything like that, where am I going wrong???
