I keep getting a high flow detected message in 1 of my zones. When I calibrated it (3min), it read out 12gpm. But when I run the zone for 10min or so, it give me somewhere between 14-15gpm. I couldn’t find any leaks anywhere and the irrigation system just got installed. Is there a potential leak underground? Or should I just run the calibration for 10min instead to get a more accurate reading? Maybe 3min isn’t long enough to full pressurize the system or something?
Any help would be appreciated. Thanks.
