    Concerns after first cartridge filter clean

    We are in the middle of a SLAM and as part of the process we cleaned the cartridge filter yesterday for the first time. That seemed to go fine, but when we started the pump again it made a slight squealing/"urching" sound which eventually dissipated. It had never done that before.

    I made a note it the filter pressure after cleaning. 13 psi.

    This morning I checked pressure and it was down to 11. Since then, due to the SLAM, we've scrubbed the skimmers and vacuumed out crud (cement, dirt etc) from the capped pipe at the bottom of the skimmers. I just checked pressure again and it's at 10. I can also hear water running through the pipes at the pad which I never heard before. The sound at the pump returned too, but less than yesterday. I opened up the strainer basket and felt inside for debris near the impeller, but it felt all clean.

    Do any of these issues sound concerning, and if so, what do I need to do? Thanks for any help you can give.

    I would open the cart filter up again and verify that you installed the cart properly. It's usually the last thing that you did that is the problem. Worth looking at.

    Thanks for the suggestion. I'll have my husband check it out and see if it helps.

    Is hearing water flowing through the pipes normal?

    Not sure what the problem was, exactly, but the above issues have seemed to resolve once we opened up and reassembled the filter. Thanks for the simple solution!
