I�ve hear that if one has low water pressure it�s better to run smaller pipe (say �� as against �� or 1�) to maintain highest possible water pressure. I�m running pvc for my sprinkling system and had thought that a larger pipe would allow greater flow to the sprinkler heads. The sprinklers themselves would provide the �pressure� by narrowing the stream of water as it sprays out.
So is it best to run smaller pipe in a low-pressure situation or does it really matter so long as at the pipe�s termination it narrows down?
