I have a new 1.5 hp sprinkler pump to draw surface water. The pump is next to the lake, with 12 feet of 2" hose between the pump and water, with a checkvalve at the end of the pipe. The vertical distance is 3 feet. Then I have 70 feet of 1 1/4 inch pvc going to the sprinklers.
I had it working once, and it easily primed by turning on the city water (which is still cut into the sprinklers via a valve with backflow) and letting the city water fill the discharge pipe and pump. The water will also flow into the intake pipe in this way.
I dont' have a T pipe at the pump. I know this would work too, but filling the outflow pipe IS filling the pump. I looked at the checkvalve and it's facing the correct way. Even without it wouldn't draw.
What am I doing wrong?
thanks
Doug
