Locke Well & Pump Company

I have your model 7gso7422 submersible pump. For the last year I have had very low pressure. Just recently ( a week or two ago)it has been pumping non stop when the water is on and has raised my electric bill a lot. 2 days ago it just stopped working. Any idea whats up? I have another one of your pumps for back up, same model but have no clue how to replace it.
Any info would be greatly appreciated.

Sounds like the pump is wore out if it is not making pressure. Or, could the pump be breaking suction? I would guess it is just worn out.
