Finally have permit in hand and am going to be installing a new AGP and want to hard plumb the system.
I'm trying to think through where to locate valves and unions. Not sure where it makes the most sense for the unions to be able to disassemble the system.
I was thinking skimmer> ~9" pipe> valve> ~4-5' pipe > union> ~9" pipe to pump> pump>filter> Aqua trol/cell>~4-5' pipe>valve>9" pipe> return.
I have 2 unions, but the aquatrol seems to have unions on either end so not sure I'll need the 2nd. I was leaving the 9" gap around the union & valve to allow future repairs if I need to cut something.
