Sunken 24' round AGP - equipment above waterline about 30ft away-
I plan to install a Jandy check valve before the pump.
I'm toying with the idea of ball valves between the check valve and pump, between the pump and filter and on the discharge side of the filter -
Do I need any or all of these ball valves? Will there be a circumstance down the road when servicing in which I'll miss them?
Just want to make sure I do things the best way the first time-
