Location of a Water Hammer Arrestor.
I'm trying to minimize the water hammer emanating from my fixtures. I know they are typically placed as close as possible to the fixture's valve. But, instead of placing one at every single fixture, I was thinking about creating a whole-house arrestor by placing it at the end of a long run of pipe right before it goes into the home-run manifold. Is this a good place, considering the physics of the water hammer?
I'm speculating the water hammer is created because of the long run which allows the water to pick up momentum. By placing a water hammer arrestor directly at the end of the run, it'll take the full force of the impact. I'm also considering using water hammer arrestors built into elbows rather than a coupling. I'm speculating they are more effective than ones located above a coupling. If it's located at an elbow, I'm speculating it would soften the direct run more effectively. At the top of the coupling, most of the water momentum would simply travel forward, bypassing the arrestor. Does anyone know if this is true?
Where can I buy the chamber-style arrestors with a diaphragm?
I've read the ones with pistons eventually fail while the ones with a diaphragm are much more reliable. And, some are even rechargeable. Does anyone know where I can buy them for a fair price?
