Very good article explaining the details of how wells actually work. It is good to see it in a picture.
Something similar happened to us last year, during a drought situation. The water simply stopped flowing. We knew nothing about the setting here so we called a professional.
It took us a while to even find the well, which was embarrassing, but it turned out to be under the house. The expert had never seen such a setting.
In the end it was a broken pump so he had a bunch of people involved in hauling out the old pump, 250 ft deep, through the house, and replacing it with a new pump.
Four days without running water.
Yes, we now keep a lot of drinking water saved and have 3 rain barrels supplemented with 5 gal buckets for outside water usage.
We are very careful about our water usage now.
Wow, that sucks! That is weird that it's under the house. If you have to service the well itself, drill deeper, etc, that would make it incredibly hard.
Indeed very odd. and what a mess to haul it up and through the house.
I hope it was well done!
