Use PVC schedule 40 (or other pressure-rated pipe) to connect the main shut-off valve to

he valve manifold(s).

Important: Use pipe one size larger than your supply line. Using pipe smaller than the main supply line will reduce your water flow

and will lead to gaps in spray coverage. (For example, use 1" pipe if your supply line is 3/4")
