My hot tub is separate from our pool and elevated about 30 inches above the pool water level. We have two modes (water circuits) pool where pump water is returned to (2) pool wall outlets and (1) return in the hot tub with a waterfall feature that spills over to the main pool. The main pool also has (2) floor returns. These two mode are controlled with (2) Jandy valves.
The second mode is hot tub only with (6) outlets and (2) floor returns. My problem of late is an air burb which occurs when I shut the hot tub off... shortly after the pump shuts off I get a big air burb from the side wall jets. The pump is hard to prime afterwards.
The system seems to be ingesting air from somewhere. My o-rings on the pump filter lid and cartridge filter appear to be in good shape. I haven’t noticed any water leaks on abnormal water level drops.
Any thoughts or suggestions?
