Quite some time ago I took my Southern Cross windmill out of service and installed a solar powered pump sold under the name of EcoWorthy. I had some initial problems because the solar panel I installed were too high a wattage and cooked the pump. I changed the panels. Fortunately I had bought a spare pump and within 15 minutes I removed the old pump from the bore and put in the spare. When I went to buy another spare I found the Velor brand one which is identical to the EcoWorthy brand and would have been made in the same factory. In action the pump lifts water up from the bore and pushes the water through 450 metres of 50mm pipe up to a water tank that is 51 metres above the pump and provides me with my daily water needs. So I recommend the pump and replacing it wnen neccessary is an easy job for an old bloke like me.
