Pe-pipe a 2 in well.

There are some YouTube videos I watched where they cleaned out a well using an air hose and a portable compressor. Drop a nozzle down it and see if the sand + water will blow up and out.

J.J. you realize we expect you to come up with a hydraulic solution for this, don't you? At 20 ft, can you rent a portable drill or even pound down a new well pipe and point? I'd like to try to pound a new 2" well for my water pumping windmill...

The old casing has a hole in the steel pipe, there is no fixing. There are a few things you can do to nurse it along but it needs to be replaced with a new well.

not sure where you are located in Jax, but i am fairly familiar with wells in the area. you definitely have a hole in your casing. (steel) "rock" wells in your area are driven until the steel pipe is set into first rock, then the rock is drilled out.. no screens, no nothing.. casing to rock, then open hole through rock. the natural ground pressure then pushes the water from the rock up into the casing to whatever the water level is.

i wont say the well is "unfixable", because its not impossible. but.. if the well is stopped up completely with sand and doesnt even produce water anymore.. that makes things much tougher as it has apparently been pumping sand for some time and should have been addressed long before now.

with that said, 1200$ for a new well is a steal (if its a competent driller).. and i would say anyone pushing another steel well isnt very competent. whats the definition of insanity??? 60 yrs ago they made good steel, nowadays you'd be lucky to get 10-15 years out of another steel well. .. get someone with a good rotary rig to drill you a pvc well and you wont ever have this problem again. good luck!

This is sort of what I am thinking, Reline the 2 in casing with 1 1/2 PVC pipe with inside fittings. The bottom of the PVC would have a ring around the outside bottom of the PVC to seal off any more sand getting into the well. Then pour hyd cement in between the 2 in casing, and the 1 1/2 PVC. Then sending down an air hose and a water hose to flush out the sand. Would that not bring the old well back to almost new status? Has anyone ever done this or heard of anyone doing this.

If this should work, I expect the water to come up the PVC to about the 10 ft level. I was pumping about 12 GPM's out of the well, and maybe that capability will return after everything is finished. As I said before, there was a 1 in drop pipe with a foot valve, pumping with a 3/4 HP pump.

If I only had an underwater camera, I could see where, and how far down the rusted out section is.

Your plan might work JJ but the problem you will have is getting enough air downhole to lift the sand up and out.. no doubt you'll need some kind of material to mix with the water to help lift the sand out... in rotary drilling they use a drilling mud for that purpose. They sell a polymer to serve the same purpose when drilling with air... Check with a drillers supply company. Good luck ..

Yes that method will work J_J.

The well bore should be cleaned out first so the liner can be run.

Calculate the amount of cement required to fill the casing between the original pipe and the new poly pipe. That will let you know when enough cement has been used.

Does the original pipe have any perforations at the bottom ??

Measure down to the level of sand in the original casing. That may tell you where the casing starts having holes??
