Triangle Well Drilling sells only the top line in pumps and components. We believe that "It only hurts once, when you do it right".  When shopping for a pump system make sure that the equipment you are purchasing is of top quality and be sure and ask about a "written warranty". If the price of the pump systems sounds to good to be true, it probably is. Be careful, some companies sell "seconds or discontinued".  Triangle Well Drilling sizes the pump system to the depth of well, production of well, distance to house, elevation change between well and house, as well as what the customer plans to do with the water, i.e.; irrigation, pasture, etc.
