Does anyone know anything about Jetmatic pumps?
I work with a fellow from the Philipines who has been telling me about a hand-operated well pump that requires no electricity whatsoever, and it will bring up water from 500 ft/ 170m deep.
I've been googling it for hours, and have found lots of references to the use of them, but only in the Philipines, and I can't find a source.
Is the jetmatic a type of pump, or is it a brand? If it's a brand, what type of pump is it?
If anyone knows about these pumps, I would certainly appreciate some info or websites on them. I am in the U.S.
