pumps with single
discharge to through- hull
pumps: 2] 1200gph 12v pumps w/ float switch control
plan "a": each pump gets it's own check valve, all pumps
connect to a manifold/collector and proceed to a
siphon break and then to discharge port [1.25"-1.50"]. check valves
to be hinge type to present the least resistance to limited pressure
produced by small pumps.
1] should check valves be located as close to pumps as possible to
reduce the possibility of drainback cycling or as high as possible to
reduce the head
pressure for the pumps to overcome on start up?
2] is the use of a siphon break redundant considering the use of
any insight you might have would be greatly appreciated.
