I have a Star brand jet pump that is currently not pumping. The pump has two sources of water to draw from, a well and a cistern. Because of this I have two pipes that can feed the pump depending on which valve is open. the well is about 12 to 15 feet deep and the cistern is the same. I have power and I have taken the pipes off to make sure the foot valves are functioning and the pipes are clear. On the snout I have 2 little access plugs that are about 1/2" diameter, one is located on the right side and centered on the inlet and the other is located below the the inlet. I have removed the plug on the side and the one below the inlet and there is no obstruction that I can see in the snout. What is my next step, what could be preventing me from pumping water.
