I have a Simmons pitcher pump, I lose power for more than 7 days every few year. My well is 225 feet deep, static water level is about 18 feet, my house is downhill from the wellhead, I estimate the pipe from the well is about 10 feet below the well head. I disconnected my pressure tank one day, connected a pex line to the bottom of my pitcher pump and I am able to draw water through the existing submersible pump. It's my long term grid down plan.
