Water hammer occurs when the flow of moving
water is suddenly stopped by a closing valve. This sudden
stop results in a tremendous spike of pressure behind the
valve which acts like a tiny explosion inside 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.
