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
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!
