What happened?
I’m the sprinkler guy at this place. The irrigation system is fed by a 3000 gal holding tank. The water wasn’t turning on and all wiring was ok on the sprinklers so I checked out the pump room. Our holding tank is full and the second I turned on the second controller I heard a beeping noise from the pump area (could be the pump controller but it didn’t beep a second time when I turned the sprinkler controller on again so I can’t tell). There’s never any water in this area even after rain and it looks like there’s some type of oil. I refrained from touching anything in case I get shocked.
Did something blow out on the outlet pump? There’s no psi minus the gravity fed water from the holding tank
I have a voltage meter, what should I check first?
Thanks in advance
