|In response to Re: Water Hammer|
Given the proper circumstances, it can happen with either quick opening or quick closing. In a residence it is usually quick closing. In a situation with a large, long water service, the water inertia keeps it from moving. If a quick opening valve, i.e., a Sloan flush valve, is operated, the pressure will drop to zero momentarily and then when the water starts moving will create a water hammer that can crack pipes if they are not anchored. In this situation, an X-Trol type tank near the usage will maintain the pressure while the water's inertia is being overcome.
