" To my way of thinking, a few 55 gallon plastic drums in the basement, filled with well water in advance and treated (bleach is OK if your well water is otherwise fit to drink) is a lot less trouble and safer for you and your neighbors who are tapped into the same aquifer."<br><br>I have to say that I agree with this line of thinking.<br><br>As far as hurting the pump. I have yet to see a pump that could be hurt by such low flow rates. That is assuming that the pump will allow water to be siphoned through it. A vane type pump will not allow water to be siphoned through. I imagine that a submerged pump would be the vane type. Possibly a roots type pump with two gears. (which wouldnt allow it either.)<br><br>To be honest, two lengths of pipe run parallel to the original in the casing would be quite cheap and easy. That would take you down 40 feet. It would eliminate the complexity. <br><br>If you have a six inch casing, as my well does, there is plenty of room for more than one line.
