In my past two runs I have received two high flow alerts (I don’t have mine configured to auto-shutoff) from the wireless flow meter, each one from a different zone. Both were essentially exactly 10-11% over (the alert occurs at 110% as preconfigured). Each was between 0.4 - 0.7 gals per hour more than expected. For now I’ve upped the alert threshold to 115% of each zone to prevent the alerts unless it seems a bigger error / leak. I wonder what a real world popped head or broken pipe would “look” like, would it be a massive use increase?
I personally can’t see anything wrong with the zones and the difference seems quite small. My plan is to recalibrate for a long period of time before the calibration is taken and see if that makes a difference (I used the 1 minute time standard and certain they look up to full pressure by then but who knows?). I calibrated during the day (no water being used in the house) but perhaps I should calibrate at night at a similar time as when these zones typically run? My setup is a 1 inch copper setup with shark bites exactly like the video, it couldn’t be more identical and went very well.
Thoughts? Is 110% of flow rates in my zones that vary from 4-8 gallons an hour too precise a calibration alert window or is something really going on with my irrigation system?
