I just overhauled my plumbing with a new VSP and SWG. I re-used the sand filter but did the deep clean from the stickied thread. Now I cannot get circulation with the various combinations. Here are the multi-port setting with results:
Filter: Pump will not prime, little to no flow returning to the pool
Recirculate: Same as "Filter" mode
Backwash: Prime surges but I only got the pump to fully "run" once, pumping out of the waste port
Rinse: Pump will prime but pumps considerable concentrations of sand out of the waste port
Waste: Full prime and shoots out of the waste port
When doing the clean, the stand pipe did float around some but I put it back into what felt like the proper place. Could I have scrambled the ports when I took the multi-port apart? I really don't think I broke a lateral with the water hose, but could that be it? I ran the "Rinse" mode for several minutes which I thought would clear out some residual sand. However, after all of that, the Filter/Recirculate are just as ineffective as before. Any ideas?
