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 non-compressible 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.
The water hammer Arrestors are designed to eliminate this effect with Lead Free*requirements.
Dishwashers, clothes washers, fast closing positive shutoff valves incorporated in the system all contribute
to creating water shock which is not only annoying but damaging to pipes and appliances.
The WATER HAMMER ARRESTERS, KWANG WOON Series THREADED and SOLDER incorporates
a pre-charged, permanent sealed air chamber to absorb the shock, The sealed chamber
prevents the loss of air to the water and insures long and trouble-free Life.
