Groundwater in well

[Oggie]

Our well is 4" PVC pipe, but it is capped with 6" PVC pipe. The 4" ends about 30" below ground level. The 6" goes from there (actually a bit lower than there, the 4" is nested in the 6". I don't know how far) to about a foot above the surface. We got a lot of rain this weekend and water in the house turned brown.

What is the best way to seal out groundwater? Is there a reason not to just dig down and put a glue transition PVC fitting between the pipes?

I am not real certain how far below ground level the 4" pipe comes up to, but if it isn't well above the ground surface, I would take the 6" cap off and add enough 4" with a glued coupler to bring it about 18 inches above ground. Then put a cap made to let the pump wireing enter the well. Where does the electric line go into the casing now for the submersible pump? OR do you have a submersible pump??

I just got off the phone with my wife. She had a pump guy look at it. It looks as though someone hit the original well casing with a vehicle and then did a quick fix. The well isn't code.

The 6" wide section is supposed to extend 20 feet down, encasing the 4" pipe and then extending 9 or so inches above the ground.

It's a submersible pump and I don't really know how deep the well is. We've lived here about 6 months.
