I want to lift water about 20 feet from my truck to the storage tank on the second floor of my cabin.
I used to be a commercial diver, and have used many types of "airlifts." This is a device where a suction is created by venturi-ing air into a line in the direction you want it to flow. In real underwater conditions, the air expands as it rises, increasing the suction power. It really sucks up whatever is in front of the nozzle.
I was playing with the idea of buying a pump that I could pump water from my truck tank up to the storage tank of the cabin. (This is just for winter use. In the warm months, there is a water system.) I am running into the problem that a lot of them just don't have a lot of head pressure. And they cost a lot. And they require special plumbing connectors. A small compressor would not have to put out a lot of air to lift the water in a
1/2" line and get it to rise up. The bubbles will push the water up and rise automatically.Anyone else ever done this? Venturiing is a good way to make suction devices for all manner of applications, and they are really safe because they just use air or water.
