This is a pump to hand pump water, and one would want to make one to save money over buying a metal hand pump or electric pump - is this correct?
Can it be reasonably made from anything else besides PVC?
Thanks for posting this info.

Mostly it is used in the developing world. The reason for being pvc is it is light and easy to find (+cheap). We can put a bunch of the parts for these on planes or walk them in. Metal pumps are heavy and fall apart real quickly especially dragon pumps (the bane of Chinese production). The pump is great as well for mobility. We used one to water fields all we did was pick it up and move it along the river. when we wanted to water set the end down in the river and pump away.
