So I received a water pump for Christmas. It was an expensive gift with a lot of thought behind it. It checks all of the boxes, pumps at 3.5 gallons, can run dry, self priming, 12v, 4 diaphragms, but, it is meant for washing down a deck of a boat and not for potable water.
The parts that come in contact with the liquid are: glass filed polyprpolene, santoprene, nitrile, stainless steel. The only difference with their potable pumps is instead of santoprene, they use monprene.
I know some people use bilge pumps, or submersible pumps that are also not designed for potable water.
I am okay using this pump and not taking the shine off of a great gift, or do I go back to the gift giver to see if he could exchange the pump? He may have got a deal on this pump, that may not be available for other pumps.
Edit: I read about santoprene, the only component that touches the liquid, that is different from the potable pumps and it is considered food safe. So it may have to do with how the bearings seal, or simply the company did not want to go through the expense of getting the pump certified for this application.
This may now free up some cash to build the RO.
