Hi Folks
I am running my sprinkler system with a lake pump. I have noticed recently that the pressure/flow in the system drops after the pump has been on for a while - say 2- 3 hours. Until then it operates normally. The pump is 5 feet above the water surface. The foot valve is 4 feet below the surface. I have checked the foot valve for obvious things that might restrict flow and have not found anything. It is 4 years old though and I suspect it may be the problem. Any thoughts ?
Thanks
