My cleaning system is on its own dedicated pump. But the main drain a two opposing jets facing the drain are on the filter pump. It's a PCC2000 system. I noticed the main drain not having much suction, some but not like I noticed before. I also noticed the debris catch/canister on the deck lid not having much turbulence pulling water in. The lid is held on tight due to suction but can see some trickling of water behind the dome. I also don't get any debris in the debris net, just a few small pieces.
I was told by pool service after blowing the line that the Jandy valves were sucking air, I had lids and O rings replaced thinking this was the solution. But tonight I noticed no change at the debris canister, same suction but no massive water flow in.
Ideas before I gave the pool guy back out. I am not in the mood to pay for troubleshooting and buying unnecessary parts.
Thanks in advance.
