If I have a 1" lateral that has 3 I20's on it, and the feed is between head 2 & 3, how long of a feed can the funny pipe be? Do I NEED to go with 1" PVC until about 2' from the head, or will 4-5' of FP be ok? Also, on the other end, do I really need to go from 1" to 3/4" between heads 1 & 2, or would it be ok to stay 1" all the way? (Particularly if head 3 has the longer FP on it). I guess what I am asking is will it hurt anything to use about 5' of FP to feed a rotor? What about a spray (1804's)? Thanks, F6 P.S. Got all the trenches dug today, 1-1/4" mainline halfway ran, had to stop for the night. Tomorrow, the manifolds!
