Hi all,
I've posted previously about a situation I've been troubleshooting. My well pump sometimes trips off for a period of time after some high current and possible rapid cycling. It doesn't happen during normal use (on/off cycles while showering, doing laundry, etc.), just during extended run times when I'm operating my in-ground sprinklers. The irrigation system is set up to have the pump run continuously while a zone is on (sprinkler nozzles are set up so that the pressure is somewhere between 40-60 psi while in operation, so the pressure switch doesn't reach it's cut-off setting until the sprinklers shut down).
An observation I made is that when a couple of sprinkler zones are operating, pressure at the well tank is between 58-59 psi, which is very close to the 60 psi cut-off setting (40 - on, 60 - off). Most of the zones operate with a pressure at the well tank of 50-55 psi.
This got me wondering if operating that close to the cut-off pressure could be part of my problem. I would think, though, that if it did reach 60 while the sprinklers are running, it would simply turn the pump off until the pressure dropped to 40 and turn on again. But is there any scenario where the switch operating right at that edge for a longer period of time could cause the switch to quickly chatter open/closed, pump to cycle rapidly, and pump to trip out on high current?
Thanks in advance.
