FWIW, if you ever install or replace a water pump the biggest pump on the shelf may not be a smart upgrade for you. If your well has a 1/2hp pump and you install a 1.5hp pump, you'll find that it starts harder and runs shorter. Ideally you want a pump that runs and never shuts off as long as you are using water. You want a pressure tank to let the pump run about 60 seconds when it needs to touch up the pressure.

bigger is NOT always better.
