out at my B.O.L I have a 12 volt DC Well pump (e bay) 75 ft.down in well,I use it in emergency off a (4D ) 12 volt battery, puts out 95 PSI @ 3 gal p, min plenty water,but let it drain back .to prevent freeze up. since i dont stay there.other well on property had 220 volt pump 455 ft down, burst piping & expansion tank last winter.
PS there are 12 volt DC water heater tank heating elements .I got mine off (e-bay)- company in Salem ,Va,
We had a natural spring sprang up in our front lawn turning it into a small pond and not in a good way.
So, we put in a dug well, with drain pipes to drain rain run off into the well.
Then, we connected into the well a over flow pipe and directed that down past the barn and into the small drainage ditch there. I can fill a 5gal bucket in about 3 minutes. It is what I use to water the live stock. Run year around.
Thinking about doing an experiment and making a water cooled container to keep things cool/cold.
