Problems with pitless adapter

[DorsalSpine]

There was a pipe threaded into the top of the pitless adapter. It rusted off right at the threads. Now we can't get the old pipe out, we can't cut new threads into what is left. It's five or six feet down. Short of digging it all out what can we do? Is there any kind of fork or sleeve that can grab under the pitless?

An easy-out welded to a steel pipe might have done it.

But your method works for sure. Steel or PVC casing? With steel, they would have welded the new casing. Could even improve it while they are at it in some cases.

PVC casing. They tried two different taps attached to a pipe to see if they could get anything to bite. What's left of the old nipple is in the way. I'll ask about an easy out.

If you can loop a nylon strap under the tongue but not pull on the shoe you can get it out. Run a string under the pitless an pull the nylon strap through as needed.

I caught a break. Did a little digging around the well casing and discovered a 4 ft square concrete lid under a couple of inches of dirt. Once I removed all the dirt I found a 20" x 20" concrete access hatch. The guys pulled the lid and found a concrete vault (4' x 4' x 6' deep). They said it was one of the easiest "holes" they had worked in. They cut the PVC casing and pulled the pump. It's an old well, PVC casing to steel to another smaller steel pipe. The last section is only four inch casing. The pump barely fit and every time it ran it rubbed the wires against the casing. The insulation finally wore through and shorted the pump. That explains why it would work some of the time.

The PVC casing was loose so they fixed that and dropped a new smaller diameter pump. They made sure all the wires were secure. The old pump was 27 years old and running fine. Too bad the wiring job wasn't as good. Thanks for all the suggestions.

I have 4 inch steel all of the way with a clearway/thruway pitless that can accept a 4 inch pump. I had my 12 year old 3/4 Trimline StaRite. pump put back when I had my pit demolished and the casing extended.

If I had it replaced, I would go with a 3 inch SQ pump, and probably with a 3 inch flow inducer. The new smaller diameter pump probably was a Grundfos SQ.

I don't think they would have allowed a steel to PVC transition. They should IMO. They also required the pit be demolished.
