Our city has untreated water for irrigation systems, but I only have 48 psi at the best, and 40 psi when a lot of folks are watering. Naturally I plan on setting my timer outside of the heaviest usage time.
Using 1" sch-40 PVC, I can get 13 gpm, but I can't find anywhere what flow rate you get at 40 and 50 psi through a foot of 3/8" ID funny pipe with their 3/4" L-connectors on each end. I'm just looking for a ball-park figure. Hopefully 3-4 gpm.
Orbit is a local company and their design gives me two zones for my approx 40' x 40' front yard. One with a Voyager II head in each front corner, and the other zone with three Voyager II heads along the front of our house and drive due to the 4'x12' walkway from our driveway along the side of the attached garage leading to our front door.
If you have the answer, or first hand experience with this kind of low pressure, please share your knowledge.
