Wanted: 1 Instructible for a hand/foot-powered water pump!!
I'm having a very hard time finding an Instructable or just easy to understand instructions on building a hand-pump or foot pump for a sink that doesn't require electricity or anything other than man power to operate. I need a design that uses pressure to carry water from a jug/bucket/barrel and dispenses it into a sink that's up higher than the water supply. I.e., a hand-powered sink. Like something you could install into an RV or conversion van.
I'm very surprised that I can't find something like this on the internet, least of all detailed instructions or a diagram of how the system works! Any help or ideas would be MUCH appreciated!! Thank you!!
