Product Name: Model 120.MSA Bronze Water Hammer Arrestor
 
S.W. Brand Model 120.MSA Bronze Water Hammer Arrestor
 
Description:
 Water hammer is usually recognized by a “bang” or “thump” in water lines. The noise occurs when a closing valve instantaneously stops the flow of moving water. This sudden stop results in a pressure spike behind the valve which acts like a tiny explosion inside the pipe. This pressure spike will reverberate throughout the plumbing system, rattling and shaking pipes, until it is absorbed.
 The water hammer arrestor helps eliminate annoying and potentially damaging water hammer. The water hammer arrestors incorporate a permanent, pre-charged sealed air chamber to absorb the water shock.
