I have an old irrigation well I would like to use to water some cows this summer.  It is only about 4 foot down to water.  I need to pipe it 600 feet or so.  Would probable get some black poly and run it on top of the ground under the hedge row.  I have a solar panel and controller I use to charge a 12v battery for a fencer.  I'm not using it now so thought about a 12 volt pump.  There are the submersible pumps that should work.  I wish they had a simple pressure switch like the 12 volt pump on my planter.  Tank would get full and pressure would shut it off.  Looking for simple ideas to try something.
