We just winterized our cabin and moved the water tank from the driveway above the cabin to underneath the cabin. The cabin sits on a hill and the pressure pump is located in the original spot which is under the cabin also. The pump is several feet above the bottom of the tank. When we primed the pump and turned on the faucets, we got no water. However if we use a hose at a lower level than the pump and tank, we can run water thru it with pressure. We're not sure what is wrong.
