I had new sand, fingers and new multiport installed on my hayward sand filter. Pressure was a nice 24 psi on the m-port gauge and stayed that way for weeks. I went on vacation for 5 days and some storms blew through resulting in a lot of debris in the pool (leaves). I cleaned that all out but noticed my pressure is 16-18 psi now and was that way before I started cleaning. I cleaned out the pump filter basket before cleaning vacuuming, wasn't too bad but had leaves in it and pine needles, sucked in from side drain under skimmer I assume.
Any ideas? Oh, and a frog somehow made it to the pump filter basket, guess he went on a ride.
