I just bought a foreclosed property that was winterized. I am having trouble with the water, there is a shallow well pump and 7 gallon tank in the lower level plumber to a shallow well tile. It was supposedly winterized, but at some point it appears someone kicked the pump on, as it was humming when we went in for a final inspection. When I turned the water on there was maybe 20 psi in the tank which dumped into the house plumbing, and ran but did not refill. The pump runs and shaft spins. I started by repriming etc, and graduating to disconnecting from the well line to eliminated outside freezing problems, and connected the pump to a short line with a foot valve in a ten gallon tank of water. When primed with the line full it sucks minor amounts and shows about 7 psi. It never gets above that or shuts off. Pump toasted? Other troubleshooting I should try before buying another? When I ran it without a foot valve ans shut if off, a large amount of rust came back out.

I need to replace my 1hp submersible pump. It has a control box that is located away from where the pump is located. All of the data that I am reading says that if I have a control box, I need a 4 wire pump (3 wires plus ground). Only problem is my pump only has 3 wires. I was told by someone, that the older pumps with control boxes only had 3 wires. So, if I am replacing the current pump, with a new one that uses an external control box, do I need to string extra wire from the control box to where the pump is located??? This is all underground and the distance is about 100 feet, probably with current wire run through a plastic conduit, but not sure. What are my options?? Can I replace with a pump with internal control box and just not use the external control box?? Is this an option???
