I thought I would share. As so many of us are off grid pumping water efficiently is of utmost importance. Sure you can do the RV pump for very low head wells without much back pressure but they wear out pretty fast. Then comes the Jetpump a beast that although is very simple with little maintenance will consume 1kW Hr to pump 5 GPM and has a starting rating of 2kW. If you have a shallow well Piston pumps are a great answer. Extremely long lived and easily maintained they will pump greater then 5gpm using slightly more then 300 watt Hr with a starting wattage of 450watts Here is a link to my restored and running Duro 255. Forgive the horribly neglected garden in the shot. Cost of the pump used: $70 rebuild kit $20 probably good for another 60 years. It was fairly easy to restore as all the main fittings were brass so they released easily. A third the energy for the same water flow at the cost of some maintenance...
Cheers, David
