OK, I've got a pretty big problem with the pressure. Couldn't find the meter I used to measure 100PSI and found my spare. It read 128PSI.. Yikes! Picked up a couple more at different stores today as a check. All are made in China..
Bottom line is all read 128 PSI.. OK, played with the pressure reg and no difference. It appears to have regulated it's last... Sooo, I need to rent a trencher and cut accross the 30' wide area that the feed pipe is buried in (somewhere). Until I do that and find the pipe(This should be less than 100' away from the controller) and get a new pressure reg and master valve installed at that point, I'm wasting everyone's time. So, I'll sign off for now and get things under control before asking again for help.
CI, I did measure the flow for a circuit having 4 Hunter PGP pop up rotors with blue nozzles and came up with 12.6GPM. I ran them today & checked the pressure while running, there was over 40 PSI still at the hose bibb.
Thanks all, I learned a lot.
