I cleaned my filter for the first time since purchasing the home in December. Prior to cleaning, the pressure was at 18psi, now it flicks back and forth between 16 -20psi. The needle drops to 16 then rises to 20psi within a few seconds, then it drops abruptly to 16psi. I have an in-floor cleaning system, which has worked intermittently (I think) but now appears to be working. The pressure changes appear to coincide with the zone change on the floor cleaning jets. One of the jets blows a lot of water when it comes on. Not sure if this is of significance. Water level is fine and I saw no visible obstructions in the skimmer basket. Any trouble shooting help will be sincerely appreciated…..
