Ok. In the end it will work fine. Thanks for all the help - especially with recommending the MP Rotators.

I know of entire sprinkler zones being laid out above ground (not by pros, of course) and buried after testing.

Won't happen. I ask so many questions it's bound to work.

My calculations say I end up with 33 psi. I won't install heads until I know what I'm really dealing with. I'll hook up my 200+ feet of PE, run it to the area and test actual. Then I'll dig the trenches install PE and whatever heads will work with what I have.

So, is my actual testing method valid?

If you want to build it first, and see if it works second, you got company. :huh:

I did but I thought that actual would be much better.

Why aren't you using pressure loss tables to work this out?

Test of actual PSI and GPM - instead of trying to calculate.

For example, I run a 1" PE line out 200 feet from a 1" valve. This is the furthest away that my last head will be in a zone that will have four heads. If I have psi of 32 and gpm of 6 for example, I can use heads that will use 1.5 gpm at psi of 30. Correct?
