About Water Hammer Arrestors

Water Hammer Arrestors are designed to prevent pipe hammer, or water hammer, from occurring in a plumbing system. Water Hammer is the sudden and violent shaking of pipes due to the pressure of moving water suddenly stopping or changing direction. This can cause damage to both the pipes and the fixtures attached to them.

Types of Water Hammer Arrestors

Water Hammer Arrestors come in many different sizes and configurations. The most common type is the 3/4 water hammer arrestor, which is designed for use in residential applications. However, there are also larger models available for commercial and industrial uses that require more powerful water hammer valves.

How Water Hammer Arrestors are Made

Water Hammer Arrestors are typically made from steel or brass components that have been specifically designed for this purpose. They contain a special rubber diaphragm that absorbs shock from any sudden changes in water pressure, thus preventing pipe hammer from occurring.

Industries that use Water Hammer Arrestors

Water Hammer Arrestors are commonly used by plumbers, engineers, contractors, and other professionals who work with plumbing systems. These professionals often install them as part of their normal maintenance routine to ensure that their clients’ plumbing systems remain safe and efficient.
