I checked it twice with an 18 gallon tub, only took 28-29 seconds to fill each time. It was coming out so fast we had trouble keeping it in the tub. I came off the main with 1 inch pipe, into my double check backflow and then to just before my mainifold. From there I hooked up a 10' piece of 1" poly and ran the GPM test. I have about 70PSI at the same spot. Think I have too much water pressure / GPM? I bought valves with flow control. Here's what I think is my final layout for the sprinkler syst...
adding the extra head in the back must be for double coverage in that area... I was thinking maybe I should do that. Will I be ok using the PGP-ADJ (LA) in the front or should I look at something else? I am in a high wind area so I think I should stick with the low angle heads. Is the flow of closer to 15gpm because of the length of the poly pipe? With the PSI of 70 and the GPM of 36, do you think I will be ok with (12) spray heads on the red circut? Or should I split that into 2 circuts? Thanks...
Hi, I'm trying to figure out how many heads I can have per circut to cover my back / front yard. I have 70 PSI and 36 GPM at the point where my valves / manifold will connect. I am planning on using the hunter PGP-ADJ (LA) in the back yard ranging from 25' - 33' radius. Using 1" PCV to the manifold and then 1" Poly to the heads and funny pipe from poly to heads. I am using the Hunter PGV-101MB with flow control for my valves. At this point I'm thinking 4 - 5 PGP-ADJ's for zones BLUE/PURPLE/GREEN...
