Low Water Pressure and Water Pipe Size
Posted by Jim Milner on October 11, 2001 at 12:19:18:
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?

Thanks,

jim
