How to Recover a Lost Submersible Well Pump

[bdhsfz6]

I suddenly lost all pressure and water began collecting around the well head. The well is +/- 500' deep with a 3/4 hp. submersible pump in a 6" casing. I dug out and exposed the pipe where it connects to the casing and found water spraying out around the pit-less adapter. I removed the pipe from the adapter and found it was loose where it connects to the well casing. Like a bone head, I pulled the loose adapter from the casing without first securing the pump pipe at the well head. Yeah, the pipe, pump & wiring went for a swim. As I recall, the pump was set about 30' above the well point so the iron supply pipe & broken adapter should be 30 to 35' below the well head. Unfortunately, I can't see it with a flashlight and the steel recovery cable has long since rotted away.

Since I lack any special equipment, I called the local well service company but they are still backed up due to the pandemic. They say it could be a month before they can get out here. Luckily, the well serves just the barn and I'm carrying water up from the house for the livestock.

I could put the system back together myself if I could recover the pump. I don't have to pull it completely from the well, just enough to install a new pit-less adapter. I know the weight of the pump and 400+' of pipe will be excessive. Assuming I can grapple the pipe somehow, I'll have to rig a tripod & winch to lift it. Well drillers use a camera, special grapple and winch rig to recover pumps. Should I just keep hauling water and wait for the experts?

Any advice would be appreciated.

Is the well cased all the way to the bottom? My well is 180' deep but is cased to 150'. If it's PVC casing and the casing doesn't go all the way to the bottom it is conceivable the pump and pipe broke through the casing and is actually a lot further down than you are expecting. Then you have the issue of how to grab th supply pipe to pull it all out and what you are going to pull it with. Quite a few trip traps. My 2 HP pump was swinging on 105' of 2" galvanized, I got the pump man to pull it. It's now a 1.5 HP on black plastic.

Age and life learning lessons lead me to suggest that you wait for the experts…..they presumably have the knowledge, expertise, and equipment to do it. They should also be able to tell you if it’s not possible too. May be cheaper and less of a headache for you in the end.

That’s my thinking at least……

I'm sorry for your problems. I have to say that I'm impressed that you were able to get 500' pipe and pump off of the pitiless adapter, even if it ended poorly.

Much as I suspect that you are talented enough to retrieve the pump and well pipe yourself, I would also vote to leave this one to the experts. You have 500' of pipe in the well that may or may not still be in one piece, a safety cable that has rotten out and needs retrieving, plus, I assume a power cable somewhere. The experts should have a "BTDT" wealth of experience to get you sorted out, along with the tools to be able to purge your well of debris.

If you have a mess of debris at the bottom of your well, you don't want to be firing up your pump with it still there.

If it were me, I would probably go ahead and replace the pump at this point on the assumption that being dropped, with 500' of pipe on top of it won't have done anything great for its longevity, or the longevity of its check valve. So, I would be having the well drillers pull everything anyway.

All the best,

Peter

There is only 60' of casing, the minimum required around here. At least 200' of the well is through solid red shale ledge. That's why it's so deep.

The pump is 25 years old and I'm leaning toward doing what you did. Throw some $$ at the problem and let the experts put in a new pump on poly pipe. Might be cheaper in the long run and a lot less work for me.

I'm thinking you could weld a funnel to the end of a length of new pipe. Funnel would act as a guide. Think like aerial refueling. You might get lucky enough to re-thread the pipe enough to lift it. Are your wires still connected?

The 10/3 cable pulled out of the junction box on the well head when the pump fell. I can see the end of it with a flashlight about 10 feet down. I might be able to grab it but I'm not sure the electrical cable will support the weight if I try to use it to pull the pump.

That's so easy. I could do that with my eyes closed, but I'd need to open them to write the check to the well pump recovery guys.

The pitless adapter was partially rotted away, that's why it was leaking. It didn't take much effort on my part to shear it off completely.

I'm thinking the same thing about having the experts replace everything.

Maybe if I put on my sailor suit and ate a can of spinach?
