Excellent resource that everyone should download!
Good intro to a very useful tool for raising water from a low head source. It may seem simple, use water hammer to raise water, but the devil is in the details. Either very inefficient or wears out very quickly if not done right.
I don't think they are overly efficient if they are constructed properly. But, if you are on a river or creek, where the waste water can be routed back to it, that wouldn't be so bad. Or, maybe used to water a garden or fill a pond? Who knows? Lots of options may be available, for the waste water from a RAM pump.
