I believe that I screwed up when plumbing the main drain as I followed engineering instructions to fit a 90 degree elbow at 18? below the spa beam which has basically created a high point in the gravity line. I fully understand that if I can clear the air-lock, this will not be a problem. At no time does the water fall below this high-point.
The main drain pipe is about 180ft in length so I am aware that there could have been a lot of air trapped, but after 6 months of trying to clear this air, I am becoming very confused and frustrated.
I do not believe that I am losing any water in the pool or spa.
Here are my questions:
1) If I did have a slight break in the spa main drain line, is it at all possible that it might result in sucking in air rather than losing water? Silly question, but I am at that point!
2) The water is sanitized by an Intellichlor salt chlorine generator. Is it possible that any part of this chemical process might create a gas which would cause my air-lock to re-occur?
3) Are there any other know reasons that might explain this reoccurring problem?
jets from pumping water. If
you just drained your hot tub, it is common to have an air lock in
plumbing and you must
bleed the air out of the lines. Look for tiny bleed
screws on the end of the pump. Open these bleed screws to allow
Always do this with the power off and be ready to close them
because water will spray out with the air. If you have a bleed
top of your filter, be sure to bleed air from there too. After
try turning the power on again and see if the jets work. You may
bleed the lines several times before the jets fully function, but
should see an improvement each time. As long as you get the
air out of the lines and the jets start flowing again, the
air will work its’ way out.
If you didn’t just drain your tub and you don’t
think you have an air
lock, try the following:
1) Is the high speed pump working? If yes, skip
to step 2. If no, check
the voltage at the pump. If there is voltage, your pump is faulty
needs to be replaced. If there is no voltage, test back to the
source for open circuits or switches.
2) Is there good water flow out of some of the
jets? If yes, skip to step
If you don’t have good water flow, try the
– Take apart the pump wet end and look for obstructions or a
– Make sure your filter is not clogged and is clean. If in doubt,
running your spa without the filter and see if there is an
– Check for closed or broken knife valves (gate valves).
– Make sure the water level is not too low and the floating weir
skimmer is not stuck.
3) If you have good water flow out of some of
the jets, look for jets that
may be closed. Many jets can be adjusted for pressure and can be
off at the jet. Also look for loose or worn out jet seals and
nozzles for obstructions.
