The Eco-Worthy 12v Well Pump has finally been installed 75 feet down this old well on my property, and it actually works!
I ran the pump for about 4 hours today, and the water has turned from nasty brown to a less nasty yellow tint.
The pump will fill a 5 gallon bucket in 4 minutes, so the claims of 1.25 GPM seem to be very accurate.
For now the pump is being powered off a Kobalt 40v battery running thru a 13.8 volt converter. More info on that can be found in the playlist above.
Getting about 2 hours of run time off of a 4 AH battery.
Next step is testing the water to see if its safe to consume. I'll continue to flush the well thruout the week. If it safe then I'll probably invest in a solar panel and a holding tank.
We are on public water so this well project is mainly to create an emergency backup water supply should things go sideways.

Any advise or comments are always appreciated.
