Same idea as captaindiode.
Did it twice for 490' well. Poly piping was very common for us in northern VA.
1st time, holiday weekend. Plumber friend was out of town. Called his brother who provided troubleshooting advice and then described what to do over the phone as he was also departing for holiday.
Built a simple frame with four 2 x 6s, forming 2 big X with 2 x 4s across at base to join them, sort of like a table base.
Used a section of pipe to span across the X to serve as an axle, by boring a hole at junction of each X slightly over pipe diameter. Pipe was about 4-5 ft above top of well casing.
Put an old wheel, sans tire, on the pipe to serve as roller. Used two plywood squares bolted to the sides of wheel with hole bored to pipe diameter to prevent wheel from wobbling and serve as a roller.
X-frame is intended to facilitate pulling poly pipe without kinking it by maintaining decent bend radius.
Disconnected power cable connection at wellhead.
Made a T-handle from threaded pipe to fit to pitless adapter. 1" I think for mine.
Thread it in and pull it up. The T-handle should keep it from dropping further into the well.
This was the key point my plumber friend's brother relayed: Remember that the majority of the piping and pump and power cable are submerged so it really doesn't weigh as much dry. Buoyancy and all. One person to grip and one to pull should be all it takes.
I was able to lift it up myself (average out of shape 40 yr old strength) and with wifely unit's assistance, feed it up and over the roller.
Once there, wife and daughter pulled the T and pipe and cable out over the lawn as I fed it up and over the roller. Snaked 494 feet of piping, cable, and rope over front and side lawn. Don't allow it to kink. Replaced pump. Installed tie-wraps to replace electrical tape that was used at intervals to tie off cable and pull rope to piping. Exercised care when lowering back into well (but failed to notice a couple sections of electrical tape wrapped on cable alone).
About 10 years later, had to do it again when trouble shooting found an open in the power cable (found to be at one of the previously noted electrical tape wraps). Replaced 499 ft of electric cable. Salvaged a good portion of the old cable to serve as a long, long extension cord for 240v air compressor.
Used lawn tractor to pull as daughter was absent.
Lessons learned:
-It was not as difficult as I expected, though it had to be the hottest day of a long holiday weekend.
-It was much easier the second time.
-Wear gloves to help grip.
-Inspect everything closely (or replace if you can afford to) since you've pulled it out, before it goes back in.
-Look at installing a torque taker near pump. Mine did not have one and my friend speculated that was cause of second failure.
-Exercise caution with the cable when pulling/lowering so cable insulation does not get cut on well head. Some sort of funnel type thingy at the top of the wellhead to prevent chafe would be advised. I'm sure the pros have thing. I just used some rubber sheeting and duct tape.
-Don't kink the poly pipe.
-Always replace the nylon pull rope.
-Inspect and clean the pitless adapter threads and use thread lube.
-Bleach the living dogsh*t out of your well when done to disinfect it after dragging 490 ft of pipe, cable, and rope across the lawn containing canine landmines. I used at least 2 gallons based on some calculation, and flushed from a hose back into wellhead for awhile.
-Flush the house water system for a long while afterward to clear all of the mud, rust, bleach.
-Tell wife to not run laundry til all the flushing is done. Ask me how I know.
Not understanding your exact configuration, YMMV, however, I saved myself a ton of $$$ by DIY. One quote by an emergency plumber to do the work 3 days later was over $2K, parts not included. My buddy said he'd have priced it the same for others, but just some Crown Royal from me.
Best of luck!
