Regarding the earlier recommendation of having a three way valve on pump outlet did waste. I’m looking at my Jandy cv460 and I see a 2” drain outlet at bottom. I’m guessing I can just use this instead? I haven’t checked whether it bypasses filter or not, hopefully so.
regarding check valves , apparently Jandy recommendeds 16” of head to keep it well sealed. That’s not gonna happen , but I will ask PB if they can move it as low as possible on the vertical pipe, although I guess they would need 4 instead of 1 which maybe they wouldn’t be so happy about. That would also reduce head loss in some scenarios I think because if lower flower rates on individual pipes
I put a 90 degree check valve on heater outlet going to swcg, per Jandy versus plumb template. Seems like it would actually be better to have sweep on outlet with a straight check valve.
