Need some help with my shallow well irrigation setup. Been working great for 15+ years. No pressure tank (pump triggered from controller) This spring old Redjacket packed it in and I replumbed in a 3/4 hp pump. Wellpoint at 22' with water table at 13'. Replaced check valve with an ANKO. Takes about 5-6 cycles of priming/turning on pump gaining about 4-5 bars per cycle. When I get close to prime, I get what i suspect is water hammer and a violent wave of water/air which causes the check valve to open and i lose all prime, check valve remains slightly open until I remove it. It looks undamaged. This is driving me nuts! Thoughts
