Need to extend mainline about 400', or maybe a new line that will run about 550-600'. Here are the details: 5/8" meter at street, 3/4" sch 40 is currently hooked up just after meter and runs 200' towards back of property to feed numerous irrigation valves. Static psi is 125, and flow is 25-30 gpm.
There seems to be very little pressure or flow loss even though it should have lost about 80 psi according to friction loss chart.
I am wondering if i extend this line another 350' if i will have any pressure left at all at end of run.
My choices are continue with 3/4" pipe, size up the extension to 1" pipe to minimize friction loss, or start over near the meter with 1" pipe for the whole run, which would be a bummer to do. Also there is about 15' rise to the back of property.
Any helpful advice would be much appreciated.
