I opened my pool easily last year, but did one additional thing this year, I removed and power washed all of the filter membranes from my Triton FNSP 60 and put everything back together. I removed all return plugs, inserted the plug into my pentair pump, ran a hose backwards from my pump to fill the skimmer lines and observed the water bubbling up from the skimmers, so I know those lines are pretty full. But I can't get the pump to pull any water other than a trickle. I've poured a bucket full into the pump's basket 10 times but no go. Do I have to fill the filter up with water before I close it? Do I have to use the air relief valve at the top of the filter to help purge out that air?
Anybody got suggestions?
