This Ram pump has been working at the Buck Run Camp down the road from me for 38 years. It pumps water by collecting the water upstream and compressing air inside of the bell until enough pressure builds up to release ram and pump water up to cabin. The cabin is at least 20' vertical climb above stream. The water runs continually into the sink as there is no way to turn it on and off. As you can see they keep a bucket in sink to have a reservoir to get larger amounts at once.
It is amazing to watch this pump work in person as the combination of the sound of the stream and the splish, splash of the pump is hypnotizing. Just another way leased camps who aren't allowed to have a well get fresh water free to their camp. Mountain girl, Paula, logging out.
