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.

1010 Meets requirements of ASSE Standard 1010 and listed by IAPMO. Watts 05 Standards Fig. 1 Fig. 2 Installations shock source Watts 05 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 3 show the proper installation where the shock would be absorbed most effectively.
