Hi,
I have an outdoor pool/spa combo. Basically the Spa is attached to the pool, uses similiar equipment (pump/filter/etc) and the water runs over the top into the pool.
The Spa does not have an air pump, it simply has a pipe that supplies air - through some sort of vaccuum - to the spa when the water is pressured through the spa lines.
Problem is - it quit working. It worked for a couple of months, but now it works no longer. Water is flowing back into the air line, which prevents th vaccuum from functioning. I drained the spa, hooked a blower up to the air pipe, and pushed all excess water through the lines.
Fired up the pump and as the water started to rise above the incoming water holes (in the spa), the air pipe filled up with water and eventually the vaccuum was gone.
When I mentioned this to our pool company last time they were onsite, they told me to buy a blower. Now - the thing worked without a blower, so I don't think that's it. Secondly, they mentioned my pump is on the way out. They are probably right there. It's getting more and more noisy.
Other helpful info may be the filter thing? It's a big tall canister looking thing that reads 30 (PSI or whatever that is) when it's pumping for the pool, 50 when it's pumping for the spa. I clean the filter every week...and my pool guy tells me the two filters I have are not old at all.
I have no idea what to do next? The air pipe is not the issue, I can easily empty any back-flowed water into it by draining the pipe and blowing it out (w/a blower). Could my pump be getting weaker?
Why is this irritating you ask? Because I just replaced my old spa heater w/a $2300 super-unit, and it's just sitting there looking new and unused!
