[GBlist] deep well submersibles - AC or DC?

Richard - You might consider pumping water to a large tank above the point of use and let gravity provide your pressure.  This could eliminate the need for a pressure tank and reduce the demand on the pump - pumping the water up an extra 10 - 20 feet instead of pressurizing the tank.  It can run longer and slower when power is available instead of when water is in demand.  Of course you have to make sure if you are in a cold climate that your tank is in a location that doesn't freeze.
