Hot Tub Controls question

[gre...@my-deja.com]

I just bought a house with a exterior in-ground Hot Tub. There are
knobs on it that I was told controls the air flow. However, they don't
seem to do anything. The air appears to be coming into the spa full
force. I took of the knob and noticed that the valve just controlled
how much air came in right at the knob. This doesn't make sense to me
because I thought the air intake was at the air pump.

Can anyone tell me what these controls are for and what could be worng
with them?

Thanks,
-Greg

These valves probably control air into the jets. If you have a blower, it
would have its' own intake. If you run the pump on high speed and open these
valves, you should get bubbles from the jets.

If I correctly understand what Bob is saying, I should turn off my
blower (so there are no bubbles from that)and turn the water pump on
high. By turning the knobs, I should then see bubbles coming out of the
jets along with the water. Am I understanding correctly? I apoligize
for my ignorance in this matter, but I want to make sure it's broken
before a get a Spa Repair Person over to fix it.

Greg-

Yes, you've basically got it. Those knobs on top most likely allow
air into a line which attaches to the main water line (downstream from
the pump) going to the jets. When the pump is on and the knobs are
open (allowing air in), the water flowing past the tubes essentially
"sucks" air into the water line and out through the jets. This has
the effect of making the jets feel more powerful than when they are
just emitting water alone.

From my experience, the blower usually emits air through little holes
in the tub, not through the jets themselves. Your tub may be
different in this respect though.

If turning off the blower, turning on the pump, and opening the air
intake knobs does not produce an air/water mix out of the jets, check
to see if there are tubes going from the knob openings to the water
lines (on mine, they are small, maybe 1/2 inch lines). You may also
be able to remove the knobs completely and put your hand over the
opening to see if there is suction. If not, maybe the lines are
pinched inside the cabinet somewhere?

Everything mentioned above is how I would have put it. One small addition,
your air lines could be clogged up somewhere with an insect or whatever.
You should be able to unscrew the knobs and do the test Blayne describes.
I would then try to get a wire down through the knob opening, if possible,
to try and clear debris. Observe caution, you don't want to poke a hole in
the tubing. Also, your jets could be fouled. See if you can disassemble
them from inside the spa. Don't remove the outer ring (that seals the jet
to the spa body), just see if the insides are removable. They are on my
Hot Springs and on a Jacuzzi we used to have. Running the spa with the
jets open may clear a clog.

You can do what I just did yesterday... (same problem), I went to
the manufacturer's website and requested an install and or owners
manual. I've lived in this house for almost 3 months and still know
very little about my spa.

Here's what not to do.

I checked with just the pump on and there was no
air mixing with the water when I turned the knob. So, someone told me
to take the knob off and the valve out and using a shop vac, blow air
into it. This was supposed to push out any water in the air hose.
Well, what happened when I did this, is now when I turn the pump, water
shoots out these knobs. Time to call the Spa profesional!

Thanks for everyones replies.

The Air knobs on the side of the spa are to add
air to the jets...On then you should see air
bubbles comming out of jets, off you should not
(unless an ozoneator is conected then there may
always be air. the blower is generally connected
to holes (or buttons) on the seat and has nothing
to do with air coming out of the jets. (there are
a couple of manufacturers that are an exception
to this rule.
