No, if I leave all sprinkler heads closed, it just stays at 40 psi as well as when strinkler zones are open. When I flip the breaker the pressure drops to zero. That's why I figured a leak in the line because no pressure builds in the line past 40. So, I closed the gate valve located after the...

I don't want to go on a pump timer because the irrigation ditch is not consistent. It runs 4 days a week but sometimes from upstream water usage it is not sufficient to run the pump. It's more just in case I am not home I want the switch to be pressure activated. Does that make sense? So you're...
