Shutting the pool system down in a few hours
Small amount of air in jets only on start-up? If I shut the pool system down for a few hours and it starts up, I see no air coming in through the pump side, but I see a small amount of air come out of one jet. Now when I shut off the motor, I hear a small amount of hissing like air coming from the backwash or drain pipe hole. It stops if I cover the pipe with my hand. I have see the pool drop about 1/8″ -3/16″ over 2 days, which can be accounted for by evaporation since the pool is not covered and we have hot days and cool nights.
I don’t think it is something to fret over, but wanted to ask if the problem is the sand filter head letting air in during off times vs the other which would be a leak in the return to pool line?

i own a pool company and the first place to look is the pump pot lid.take the lid off and you will see a o ring on the inside of lid. take that off and flip it over then put lid on tight.then turn on pump.if that is not it go get one from pool store.if that still does not stop the hissss,then take filter apart and get that o ring.that should clear up the problem
You’ve got a leak somewhere. It’s letting air into the system when it’s off. Look at your seals on the filter, pump, inline chlorinator, filter for the pool sweep, etc. Pool supply stores sell a lubricant that you apply to the seals. If that doesn’t do it, you have a valve that needs adjusting.
