I had my pool professionally opened and now I am having a problem with the pump. When the pump is off the pressue gauge is reading 10 still and not going back to 0psi. It seems there is alot of air swishing around in the pump. I also noticed some water coming out from the filter water release valve. Whwn the pool pump is running the pressure goes up to 20-25 psi and the pump gets really hot. The normal psi for my pool is around 10-12. I can't figure out how to get the air out of the pump and why is it still picking up a reading when the pump is off. I have an older Jacuzzi filter so there is no air release valve on it. Can anyone help me on this? I don't want to pay big bucks if it's something simple I can look at. Thanks.
