This is my first irrigation project. Static water pressure per the water company is 120 psi. After the PRV, pressure is 55 so I plan to connect after the PRV. Supply line coming from the meter to the PRV is 3/4 copper. I have been reading Jess Stryker's Irrigation Tutorials and am confused. Am I limited to 6 GPM due to connecting after the copper pipe coming into the house? Or do I plan based on pipe sizes after the Irrigation system point of connection?
