Lenders dont touch houses here without 3 gpm minimum.
LLIg and VAwd: So you added gravel inside your open bottom casing?
I have a 4" slotted liner in a 6" well but the bottom is open and it seems the clay-mud is working its way upwards. This too was thought to be a all hard rock well.
would pouring some stiff cement down the liner be a viable way to seal off the bottom? Then use the now clogged pump to suck up the mud intrusion and re-use it or replace it....?
You shouldn't pour it in....if you want to do that, you should pump in the exact measured amount through tremie pipe, so you know exactly where it goes. The easier solution for you to do yourself, would be to get a K Packer and plug the bottom. Look at western rubber figure K packer online.....get like a 4" x 2" threaded, and put a threaded plug in the bottom...then push it to the bottom of the well. If you have a pitless adapter, you may have to remove it to install the packer, and then put it back.
