Pump Will Not Hold Prime
My sprinkler uses lake water for it's supply. I have 7 zones and primed the pump for the first time a week ago. It sprinkled as it should and shut off after zone 7. The next morning, it was set to come on a 6 a.m.. The pump came on, right on time but no water came out of zone 1. I shut the pump off, primed it again and it ran through all 7 zones. Same problem next morning. Why is the pump losing it's prime. I have a check valve on the intake pipe in the lake. Could this be the problem and is a check valve necessary? I would appreciate any help.
Check for a suction line leak.
We've had heavy rain the last two days so I haven't had a chance to check the suction line for a leak. Thank you for replying as that's the first thing I'll check as soon as it gets dry out there.
