The Watts 0121227 1/2″ Water Hammer Arrestor 150PSI is an essential part of protecting your HVAC system from the disastrous effects of water hammer. This 1/2” arrestor is designed to work under pressure of 150 PSI, it acts as a shock absorber for water flow changes. It is a dangerous pressure spike that occurs when either valve is shut quickly or flow is restricted in any other way this pressure surge can easily cause damage on pipelines, valves, and fixtures within your HVAC system. There are those that work internally, whereby the arrestor uses an inner compartment such as a bladder or piston to dispel the energy of the pressure wave.
