Well water question.

Sure Jim! FYI, after your well and plumbing is shocked, expect to have to pull the incoming water lines to things like dishwashers, washing machines and the like. This is because the chlorine treatment will break loose all kinds of crud inside your plumbing and the incoming water lines on appliances will likely have screens that will catch this. My dishwasher clogged to the point it wouldn’t let water pass at all. My relative’s washing machine did the same thing after her well was shocked.

You don’t have to preemptively do this, just be aware of this possibility if an appliance suddenly stops working.
Yeah, we had to do this when we installed the Kinetico softener when we bought the place 3 years ago. I was amazed at the amount of "gunk" that came out of the pipes, and to his credit the Kinetico guy did warn us that this would happen. If memory serves it took about 5-6 months for everything to clean-up....

For the life of me I don't know how the previous/original owners lived with that water for all those years!
