it does. I'm of the opinion that it's no flow on the inlet side. When I took the pump and impeller assembly apart, there was a thick layer of sand and soot inside. I cleaned all of that out. When i put it back together, the pump runs fine and if I use a garden hose to provide water to the inlet side of the pump, it'll spray the water all over the place, indicating that it's functioning. Just before the inlet, there's a pvc valve with a spring in it. I'm thinking that there may be sand and soot in it, blocking the flow of water to the pump. I wanted to run it by someone who knew more about these systems than I do so I don't replace a valve that may be functioning properly. I think I'll start there and see where it gets me. I priced the valve last night and it's only $10. If you have any other ideas, I'd love to hear them. Thanks again for your replies!!!!
