Well sanitizing (extra attention to 4 inch casing)

[Reach4]

Im trying to see how this changes for a shallow well jet pump system?

Depends. Can you recirculate somehow?

If your shallow well is a driven well point and a suction pump sucks on the top of the driven pipe, I don't see this technique working. If you had a well point but there was a pipe going into the driven pipe that hooked to the suction pump, and you could run water back into the driven pipe, then I could see that working.

At the top of the well pipe there is a tee buried about 3 ft from the top of the ground. I guess I could plumb garden hose fitting to the top of tee.
Starting to get smelly water from our house well water.

Have a separate well for outside that has been smelly ever since changing from a galvanized tank and air valve control or (air control valve) to a bladder tank.
