I have read through this, over and over. Something is wrong here. How can a pump with that much head pressure and GPH, run on that low of electricity AND be $40 AND include free shipping?
Just so happens I am searching for a new direction in pumps, and am trying to avoid the 220/240 volt systems I am seeing. But this just doesn't look right to me. Can I get some input here? Thank you.
