I built a few of them. The plans are outlined on my web site. That was the Amish Clack pump I mentioned in the message, as it predates MEN. They are not at all hard to build. After some playing I was able to make mine much simpler than the one from MEN. A couple of Tee's, Elbows, a Check Value put together backwards, and some reduction fittings. > pressure wave resonance in the larger pipe overcoming the spring.

One way is to make sure the valve is not at the very bottom so that heavy debris falls below it into a section of pipe that can be opened for cleaning. The roof shingles tend to wash small bits of them self into the down spouts that need cleaned every once in a while, it would foul the valve.
