Because my yard is large and the water source is off in one corner, I'm running 1 1/4" poly main feed accross the middle of the yard. The valves will come off this main feed in pairs or triples and it will be 1" poly feeding off the valves to each zone. Has anyone ever assembled their own valve manifolds? They'll need 1 1/4" hose barbs at either end. I'm not sure what to make them from. ?Galvinized fittings? poly fittings?
