| Yes, each filter line to bakki originates from bottom drains and run through the same vortex pressure prefilter. I moved the pump in question to the filter circuit closest to the bakki shower which always has worked fine. The only differance between the two set ups is the extra distance to the bottom drain (10'). I did notice that when we replace the check valve on the filter circuit in question (middle one) the intake (coming out of the ground) was reduced form 3" to 2" 90< elbow. The suction head of vortex, the intake line is about 2ft above the pond water level, and the top of vortex is about 3ft above water level. The bakki is about 7ft above the pump.
I would like to fix this problem this weekend:
1. Should I disconnect the 3" intake line underground just after the check valve and try and snake the lines to the bottom drain?
2. Do I hook up the system just like it was?
3. Or is there another way to improve flow & or prefiltration?
