Series 05
Mini Water Hammer Arrestors
Sizes: 1⁄4" – 3⁄4" (8 – 20mm)
What is Water Hammer?
The noise from banging pipes is caused by shocks of high
speed water flowing in the piping system when a fixture is
suddenly closed. Sudden stoppage of the water (a noncompressible liquid) flowing at a given pressure and velocity causes a surge or spike of water and is called water
hammer. When this occurs, a pressure wave travels back
through the piping until it finds a point of relief.
Dishwashers, clothes washers, fast closing positive shutoff
valves incorporated in the plumbing system all contribute
to creating water hammer which is not only annoying but
damaging to pipes and appliances. Series 05 water hammer
arrestors provide economical and effective single fixture protection from the destructive and annoying problem of water
pressure shock. Utilizing piston style construction, factory
charged and sealed, the Series 05 provides automatic,
repetitive control of water hammer when properly installed.

Installations
Watts Series 05 water hammer arrestors should always be
installed as close to the source of shock as possible - one
unit on each hot and cold water line.
Although they function in any orientation, Figure 1, 2 and
shock source
3 show the proper installation where the shock would be
absorbed most effectively.
