Throughout the day, we experieince short periods where the Jets that push watwer into the pool will "bubble" - like there's air in the system. When I put my hand in front of the jet when this happens, I notice cooler water (e.g., the water temp appears to be changing). Also, the pool sweep stops operating for like 1 min. or so when this 'change' occurs ... Is this normal? Our thought is that it has something to do with the water flow changing as it comes down from the olar panels on the roof - like maybe the water is not HOT, hence the solar stops flow or something. Is it possible the main Filter needs to be disassembled & cleaned? (It's showing about 25 psi - which seems to have gotten higher over the last month from 19-20 psi)
If this is NOT normal, how do we purge any air in the system? Thanks !
