Ingenious, sustainable drinking water pump

A simple, hand-operated vacuum pump is a more sustainable way to dispense water instead of the large machines with hot and cold spouts, which require electricity and take up more space.

How about using a valve, an air inlet and mounting the bottle upside down? Then no pumping is required... :D

Or if you insist on the bottle upright, then put a pipe in it like you did, then extend the pipe in the outside down under the bottom of the bottle and put a valve there. If said pipe was full of water to begin with, then no pump needed, flows till the bottle runs out of water... :)

@kistuszek Yes, but the methods you describe require extra work that requires specific know-how, which most people don't have. This pump is a simple solution that works right out of the box, with any bottle that has the same-size opening.

I just bought this water pump but do you know how I can disassemble the pump so that I can clean the spring where you press the water out? I'm worried the water will corrode the spring over time.

[raoulpop]

@okaythisisnasty I don't think the spring comes in contact with the water. That would be a foolish design. I think the water is routed through a separate channel and right out the pouring spout. Or perhaps the spring isn't made of metal, but of plastic as well.

Sounds like a great deal of work for room temperature water. Why not filter and pour?

[raoulpop]

@arbonac You're missing the point. This has no carbon footprint.

why dont u just take the pump off and drink out the water bottle

@kistuszek~ ye this is totally crap.

@nambinhvu The giant water dispensers use gravity to allow the water to be dispensed, it also has hot and cold water tanks, which heat and cool the water for convenience. Do me a favor, fill your sink with water, then fill a cup with water in the sink, and tip it upside down so that the opening is completely submerged in the water, then raise the end above the water keeping the opening submerged. Notice the water stays in the cup, that's how those water dispensers work.

@raoulpop No "YOU" are missing the point. The bottle and the pump require energy and materials to be produced. If you want to decrease your carbon footprint, pour the water directly from the bottle, don't waste materials and energy on a stupid pump. If you want to decrease your carbon footprint even more, drink from the tap, then you don't have to drive to the store or have water delivered...Those big machines don't use energy to dispense the water, it uses the energy to heat and cool it.

@kicstart Are you American or just willing to make excuses for being lazy like one?

@raoulpop

Well IF elementary physics are a problem, then i say its a nice way to bring it to people. I mean people didn't know how to use the drinking straw right?! They get water a physics demo in the same time, water _and_ education in a nice easy to consume package!! :)

"smooth is quite flow"

well done....
