After removing the well cap and adding some tablets, do you just stir up the water down the pipe with a long pc of wood for a while and then recap it and let it sit for 12 hrs or so? Yes, and be sure your pump is not connected so nothing can get into it. >> Secondly, I was going to close outlet valve that isolates the house plumbing, but leaves an outside hose tap available. I would then run my pump and flush the NeWell mixture through my bladder tank and out the hose outlet away from the house. Is this method of flushing advisable or should I put a pitcher pump down the well and flush it out that way? I would definitely not use the pump or any part of your house system to flush the well after well after a pitcher pump has cleared the well.
