Safeguarding Your Plumbing System: The Vital Role of Water Hammer Arrestors

Water hammer - a phenomenon that sends shock waves through your plumbing system, causing rattling pipes and potential damage. If you've ever experienced the unsettling noise of pipes banging after shutting off a faucet or a valve, you've likely encountered a water hammer. But fret not, as there is a simple and effective solution to this problem: the water hammer arrestor.

In this blog post, we'll explore the concept of water hammer, how it impacts your plumbing system, and the crucial role that water hammer arrestors play in mitigating this issue. So, let's dive in!

Understanding Water Hammer

A water hammer occurs when the flow of water within a plumbing system is suddenly stopped or redirected. When a faucet or valve is closed rapidly, the kinetic energy of the moving water is abruptly halted. This sudden stoppage creates a shock wave, resulting in vibrations and loud banging noises in the pipes.

The impact of a water hammer can be significant and damaging. It places immense stress on your pipes, leading to wear and tear over time. Not only can this result in leaks and pipe bursts, but it can also lead to premature failure of various plumbing fixtures and fittings.

How Water Hammer Arrestors Work

Water hammer arrestors serve as a solution to the problems caused by water hammer. These devices are designed to absorb the energy created by the abrupt stoppage or redirection of water flow, thereby preventing destructive shock waves.

Water hammer arrestors typically consist of a sealed chamber with a compressible air-filled cushion. When water flow is suddenly disrupted, the cushion compresses, absorbing the shock and preventing the pressure surge from traveling through the plumbing system. This cushion of air acts as a buffer, effectively minimizing the vibrations and noise associated with the water hammer.

Installing Water Hammer Arrestors

Installing water hammer arrestors is a wise investment to protect your plumbing system and ensure its longevity. These devices are available in a variety of sizes and types to suit different plumbing setups. Here are a few key considerations:

1. Location: Water hammer arrestors are strategically placed at key points in the plumbing system, typically near fixtures that are prone to water hammer, such as washing machines, dishwashers, or toilet valves.

2. Type: There are two main types of water hammer arrestors - vertical and tee-style. Vertical arrestors are cylindrical and can be installed in a vertical position, while tee-style arrestors are installed in line with the plumbing pipe.

3. Sizing: It is crucial to choose the correct size of the water hammer arrestor to match the flow rate and pressure requirements of your plumbing system. Consult a professional or refer to manufacturer guidelines for proper sizing.

Benefits of Water Hammer Arrestors

Investing in water hammer arrestors offers several noteworthy benefits:

1. Prevents damage: By absorbing the shock waves produced by the water hammer, arrestors protect your pipes, valves, and appliances from potential damage, reducing the risk of leaks and premature failure.

2. Eliminates noise: The constant banging and rattling of pipes can be a source of distress and annoyance. Water hammer arrestors effectively eliminate these noise disturbances, promoting a quiet and peaceful environment.

3. Improves water flow: By reducing pressure surges, water hammer arrestors can improve overall water flow and maintain consistent water pressure throughout your plumbing system.
