My home came with a Sears Delux Water Pump with a 1 gallon pressurized water storage tank Model# 770-2948 which has never been used. It's been sitting idle for 12 years. When I plugged it in, it started right up and was building air pressure from the outside spicket but no water is coming out. I was told I have to prime it. How do I do this? :wall:

My deep well pump does not kick on about once every two months. Pressure switch is set 30-50 and pressure tank at 28. The switch activates the chemical pump when the pressure drops below 30 but once in a while the well pump does not activate. The pump will then activate on its own between 5 to 20 minutes. It does not seem to happen in relation to heavy water use because it has happened first thing in the morning when someone showers. Well is 180 feet and I have not had water level checked. Could this be a problem with an old pump or with the wiring? Pressure switch is a few years old.
