Just made a home inspection with pool and run in to an unusual situation that hasn’t happened before. The pool pump was continuously running and water was circulating through the jets. What seemed unusual to me was the strainer pot never had water going through it. I’ve always saw water circulating through the strainer pot attached to the pump. Why would no water be circulating through the strainer pot.
Their was a solar energy system which was circulating.
I think it was just a valve setting. I’ve have seen lines marked as VAC for the skimmer also. Were any of the lines marked? They should be if they are not.
Just a thought, if the pump and filter system is on a timer and the heat system is manual, then heat could be energized by closing a valve and starting pump and forgetting to turn timer off for filter system Pump came on after and sucked water out of strainer.If there is no air bubbles in pump strainer sometimes it is hard to see the water in it. The other thing is, did one pump sound a lot louder than the other or were they both the same?
