Answering questions on water hammer, valve sizing and more.
I receive a number of interesting questions regarding design, operation and performance in a plumbing system. Some of these questions are worth sharing with everyone else. These questions all relate to valves. So here they are:
Water hammer does occur when there is a quick closing of a valve. The shock wave will actually occur any time there is an instantaneous change in velocity. The water doesn't have to completely shut off for hydraulic shock to occur.
