I am still in the developmental stages of my project, but I am currently at a stand still. I started to run the usual tests and realized that my GPM is very low. My psi is a pretty standard 50 psi, but GPM is only 4. It seems that everyone has at least 15+ GPM for their setups. I cannot find a lot of information about GPM being so low, only about low psi. From what I've seen most standard spray nozzles are putting out at least 2-3 GPM. So does this mean I'm pretty much stuck with using 2 sprinklers per cycle?

try to describe your supply in more detail - source, distances, and sizes of pipes and water meter, and if there is a pressure reducing valve in the supply
