Your experience may vary, but Ram pumps are hard to adjust to work well and they waste most of the water. I've hand-built and run two ram pumps as well as purchased and run a pre-built one. I even bought a book just on ram pumps to try to get it right. Also a nice PDF here on the concepts [0]

Essentially, you have to keep maintaining and adjusting the pressure chamber to get the right pressure for the correct operation of the two check valves. This means it is not a set it and forget it.

I bought a solar pump to replace it and it's run amazingly well for over a decade and I doubt I would ever go back to a ram pump unless it was truly the only option.
