How to repair jet pump well assembly

[crombienator]

My assembly is about 6-7 ft down into the well casing. My twin pipes run under ground and up through the basement to a jet pump. How the heck would I change the foot valve and injector in the well. Do I have to dig down? Do the pipes enter the well from the side? Because they certainly don't go through the cap.

There are two possibilities.

1) The house is from the '50's and there is a hole cut in the side of the casing. The pipes enter the well then there are two 90's that are screwed on with two drop pipes down to the jet. That hole was typically sealed with window screen and cement.

You don't want this, it's unsanitary, a real pain to service and expensive due to labor.


2) You have a pitless adapter designed for a jet pump system. With it, you use a long piece of 1" pipe to pull the pitless up and remove the lines & jet.

This is the type of installation you want to have, sanitary and easier to service.

Would this come out of the top of the well casing? My lines come from the ground in the basement. I don't see any other way that this could be anything but a hole in the casing.

Look down the well. What do you see? Any female threads looking up from a big brass casting?

If not, you most likely have a "picture window"..... If that's the case, the absolute best thing to do is dig up around the well, cut off the casing at the window, retrieve the pipes, then weld the pipe back together and do it over the right way..

We did one a few years ago that turned into 1.5 day job, under a sidewalk, 60 yr old steel drop pipes...... We updated to a submersible pump, new tank new lines, basically a new installation.
