water hammer is a subject usually left up to plumbing engineers, the effects of water hammer must be dealt with every day by plumbing con-tractors everywhere. Water hammer is easily recognized by the banging or thumping noise that’s heard when valves are shut off. Although this is an easy way to recognize the problem, water hammer doesn’t always make these telltale noises. Water hammer occurs when the flow of moving wa-ter is suddenly stopped by a closing valve. This sudden stop results in a tre-mendous spike of pressure behind the valve which acts like a tiny explosion pastinginside the pipe. This pressure spike reverberates throughout the plumbing system, rattling and shaking pipes, until it is absorbed. Normally, a sufficient pocket of air will absorb such a pressure spike, but if no pocket of air is present, expensive fixtures and appliances within the plumbing system will be damaged as they are left to absorb this pressure spike
