Drinking water safe foot pump?
I am trying to make a dishwashing station for camping, and I havn't been able to find a design for a pump that seems food-safe. The designs that I have found for DIY use petrolium jelly for a seal.
I would prefer a foot pump, as most of the people that I camp with are young, short, or both. :-)
Help for the DIY and physics impaired, please.
