I am using a 1/2 hp sump pump to provide flood coolant to a CNC milling machine. The sump pump has a 1.5" outlet. The milling machine already has a 1/2" adapter and manifold which connect to Loc-Line hoses that each have a ball-valve for on-off.
Where is the best place to put the 1.5" -> 0.5" reducer? I'm debating whether I should do that at the sump outlet, or if I should run a length of pipe (PVC or other) close to the sump's outlet diameter and then use the reducer closer to the manifold. Does it make a difference?
