Pool is about 12 years old now and this is the first time I've had really any issues with regards to plumbing. About a month ago I noticed a couple of the of the pool returns (including Polaris return) shooting a constant flow of bubbles. When the filter shuts off I can hear the filter emptying the water at a fairly fast pace. In the morning after the filters have been off I notice the filter is pretty much half empty. There are no leaks anywhere that I can see either. I've tried using a water hose by pouring water over various potential trouble spots but didn't find anything. When the pump is running there's no bubbles that I can see within the pump itself.
The pump on the right is the infinity edge pump and that's fine....
The main pool pump is on the left, then the Polaris pump next to that....
Also, when the pump has been running for a while and I go to let any air out of the top of the filter hardly any seems to come out, just water....
I've also switched pump lids and that didn't make a difference....
Appreciate any suggestions....
