Hi Jerry What equipment are you using to pull steel  from that depth?

I forgot how I located it, but I used a vaccumn  gauge or pump and to determine how far down the well the the leak was  and pulled the pump and pipe and found a crack.

I'm getting water flow in reverse either through the pump or a leak up to the pump. My question is if the check valve on the top of the pump is not sealing, will the progressive cavity pump allow water to flow through the pump in reverse? I'd think that with a positive displacement pump it would not, except very slowly or if it turned the motor backwards which I think would be very unlikely. There is about 100 psi head on  the pump.  I think it's most likely I have a leak somewhere in the plumbing, and of course another failed check valve farther up in the plumbing. It's possible to get failures even with redundant protection if you have two concurrent failures, which I must have here.  Brad Bassett  Old time solar guy who used to do solar pumping back in the '80's and '90's.
