Hi all... I'm trying to build a sprinkler system. I'm trying to do it VERY cheap and VERY basic because we're likely moving soon. As such I'm hoping to build a simple above ground system using PVC and a few garden hoses to be run by a sprinkler pump drawing water out of my irrigation ditch. My main confusion is this:
I've been told that it's very important to have enough impact heads coming off of my centrifugal pump so that I don't damage the pump. So the question is, how do I determine this? I guess I don't understand the relationship between PSI and GPM. How do I determine what kind of PSI/GPM I'll be producing so that I can determine how many heads I need? I'm planning on needing maybe 15 impact heads (it's about a 1/3 acre lot) and need to know if I can run that all at once off a 1 HP pump.
I know this is pretty vague, but can someone give me some good guidelines? Thanks in advance...
PS - I can provide more specifics if needed... just ask ;)
