Water draining back to well

We awoke this morning to the sound of water draining from the pipes and running back into the well. We have a submersible pump in a 345-foot deep well that was completed in 1993. The pump will cycle on and build up pressure to 50 psi and shut off. Then, the pressure immediately drops, and we can hear the water draining from the pipe again. When the pressure drops below 30 psi, the pump cycles on again, but the pressure continues to drop to zero and stays there 1-2 minutes. Then, the pressure starts to build again to 50 psi, and the process repeats itself. I then shut the breaker off to save the pump. Is the problem at the pump in the well, or is it at the bladder tank in the basement? Is this a job that will require large equipment to pull the pump out of the well? If the pump has to be pulled, would this be a good time to replace the bladder tank as well given its age? Thanks for any information you can provide.

There is a check value built into the top of submersible pumps. Some of them are really cheap and not even spring loaded. If the check value gets stuck open then this will happen. The quick fix is to go and buy a new brass check value the size of the pipe coming from the well (normally 1") and installing it right before the water tank. This will prevent the water running back into the well. As long as you don't have any other water lines tee'ing off the main line coming from well it should be fine.

Also check the air pressure in your bladder tank.
I'm not sure if your bladder tank has a rating of say 30psi
but check it, if your bladder tank has no air pressure that could be your problem.
