I have a Sioux Chief Mini-Restor installed behind our clothes washing machine, on its cold water inlet line. Previously, when the washing machine's cold water inlet valve would shut off, we would hear a "thump!" from the kitchen sink plumbing. The kitchen sink is about 50 feet downstream from the clothes washer.
The Mini-Restor I installed has a female hose thread inlet, and presents a male hose thread outlet, which is 90 degrees from the inlet. I just unscrewed the washer's cold inlet hose from the manual shut-off valve, screwed the Mini-Restor onto the valve, then screwed the washer's cold inlet hose onto the Mini-Restor's outlet. Very simple, and effective. Having the Mini-Restor about 3 feet from the source of the hammer, the rapidly closing cold fill valve, did not seem to reduce it's effectiveness.
I realize my application is a bit different than yours - I was stopping the surge at the source, where you are trying to stop the surge at the far end, the receiving end. I would think anywhere along the path has to help, as it is the squidgy accumulator effect that absorbs the surge of the relatively incompressible water.
