Hi everyone, I am stuck on a problem and looking for advice.
I have an in ground pool. Approximately 6000 Gallons.
-Hayward Swimclear 3030 Filter
-Hayward Tristar VS950 Pumps (1 for filtration, 1 for spa jets)
-Hayward Booster Pump
-Hayward Heater
-Hayward SWG
Here is the scenario I am faced with. Pump runs at medium from 9am to 3pm daily, and shuts off. Through the evening/overnight I can faintly hear air entering the filter. When the pump turns back on in the morning, I get a large amount of air being forced out of the returns. The system continues to run normally and without any air being pushed out (other than what I feel is normal when the SWG is operating).
My pump always has full prime, no bubbles in the pump basket, etc. and I don't see any water leaks as the pump/filter is operating.
My troubleshooting so far:
-Replace the metal reinforced o-ring on the filter
-closed various return valves at the pump. When I close off all return valves, the air sound subsides.
My theory is there is some sort of siphon effect where the water is "pulling" air in from somewhere, allowing it to drain back into the pool, but filling the filter with air.
Another thing to note, is when I take the lid off of the filter, the waterline seems to stay at the top of the bottom half of the filter (I don't see it draining into the pool) -- however, this is only observed over a few minutes, not hours.
Please can someone help shed some light?
