Hi - I'm looking for some advice, troubleshooting an irrigation pump problem. I've got an irrigation system using a jet pump on a shallow well. The system has 4 zones, 2 using spray nozzles and 2 using rotary heads. The system is about 7 years old and have worked fine with no significant issues. I have just replaced the pressure switch on the pump. The old switch began sticking, and would occasionally not cut off unless I tapped on it. The new switch is an identical 30/50 model, per pump specifications. The pressure regulator tank is set to 28 psi, per pump specs. Tank pressure was measured after killing power to the pump while the system was running, and then allowing it to drain off any internal pump pressure before the measurement.
After installing the new switch, the pump works fine on 3 zones. On one of the rotary zones, the pumps cycles on and off every 10-15 seconds during the irrigation cycle. When the system is turned off, the pump shuts down properly, with no further cycling. The pump does not have a pressure gauge, so I cannot monitor that. This never happened with the old switch. I'm at a loss what has changed or what to do next. Any suggestions are very much appreciated.
Thanks,
Whit
