So, I did it myself! I pulled the submersible pump at my cabin (a 220v 1/2 hp Franklin that was sitting on the bottom of the well and completely encased in a clay sediment, it was a bear to get out), cleaned the clay pack from the well screens and reinstalled the pump 20 feet above its previous position. It now pumps about 10 gallons per minute for a total of 8 minutes after a 9 hour rest (so 80 gallons) before running dry. I'm not hooked up to any plumbing (just a open pipe pouring out water when the electrical breaker is switched on). My questions are these:
1. Is it possible to run the well until it runs clear if I keep drawing the water level down to the pump itself? If not, how do I go about clearing it?
2. I shocked the well with bleach overnight, ran it out, ran the well dry multiple times, and then, for good measure, poured a gallon of bleach down the well to let it sit for a time to get it SUPER CLEAN. So, how long should I leave the bleach in the well, and what is the maximum time I can leave the bleach in the well before risking damage to my well components? Will I risk damaging them if I leave it for weeks (I've not done this but I'm wondering)?
FYI: 240' deep well, water at 110' below ground level, pump set at 220' deep, 5" casing, 1" black poly drop pipe, water flows at 10gal per min for 8 minutes before drawing down to pump.
