Understanding The Importance Of Water Hammer Arrestors
Water hammer is a common problem that many people face in their plumbing systems. It occurs when the flow of water is suddenly interrupted, causing a loud banging noise and potentially damaging the pipes. To prevent this issue, water hammer arrestors are often installed in plumbing systems. In this article, we will delve into the importance of water hammer arrestors, explaining how they work and why they are necessary. So, let’s dive right into it!

What Are Water Hammer Arrestors?
Water hammer arrestors are devices that are designed to control the sudden pressure changes that occur in plumbing systems. When water flows through pipes and suddenly stops or changes direction, it creates a shockwave that travels through the pipes, causing the banging noise known as water hammer. These shockwaves can lead to damage to the pipes, fittings, and even household appliances.
Water hammer arrestors are essentially air chambers that are connected to the plumbing system. They contain a cushion of air that absorbs the shockwaves, preventing them from causing damage. By providing an air-filled space, water hammer arrestors act as a buffer, reducing the pressure spikes and minimizing the noise associated with water hammer.
How Do Water Hammer Arrestors Work?
Water hammer arrestors work on a simple principle: they provide an air-filled chamber that absorbs the shockwaves created by sudden changes in water flow. When water flows through the pipes and encounters an obstacle, such as a valve closing or a faucet turning off, the momentum of the water causes a pressure spike. This pressure spike sends shockwaves through the pipes, resulting in the banging noise.
Water hammer arrestors are typically installed at key locations in the plumbing system, such as near valves or appliances that frequently cause water hammer. They consist of a sealed chamber that contains a diaphragm or a piston. When a pressure spike occurs, the shockwave travels through the pipes and reaches the water hammer arrestor. The air in the chamber compresses, absorbing the shockwave and preventing it from causing damage.
Why Are Water Hammer Arrestors Important?
Water hammer may seem like a minor annoyance, but it can have serious consequences for your plumbing system. The repeated shockwaves caused by water hammer can weaken pipes and fittings over time, leading to leaks and even pipe bursts. Additionally, the loud banging noise can be disruptive and irritating, especially if it occurs frequently.
By installing water hammer arrestors in your plumbing system, you can prevent these issues from occurring. The arrestors absorb the shockwaves, protecting your pipes and fittings from damage. They also reduce the noise associated with water hammer, creating a quieter and more comfortable living environment.
Where Should Water Hammer Arrestors Be Installed?
Water hammer arrestors should be installed at key locations in your plumbing system where water hammer is likely to occur. These locations include:
Near washing machines: Washing machines often cause water hammer due to the sudden stopping of water flow when the cycle ends. Installing water hammer arrestors near washing machines can prevent damage to the pipes and reduce the noise.
Near dishwashers: Similar to washing machines, dishwashers can cause water hammer when the water flow is abruptly stopped. Installing water hammer arrestors near dishwashers can protect the plumbing system from damage.
Near valves: Valves, such as those used to shut off water supply to individual fixtures, can also cause water hammer. Installing water hammer arrestors near these valves can mitigate the pressure spikes and prevent damage.
Near water heaters: Water heaters can create water hammer when the heating element turns on or off. Installing water hammer arrestors near water heaters can protect the pipes and fittings from the shockwaves.
FAQs
Q: Can water hammer damage my plumbing system?
A: Yes, water hammer can damage your plumbing system over time. The repeated shockwaves can weaken pipes and fittings, leading to leaks and pipe bursts.
Q: How can I tell if I have water hammer?
A: The most obvious sign of water hammer is the loud banging noise that occurs when you turn off a faucet or an appliance that uses water. If you hear this noise frequently, it is likely that you have water hammer in your plumbing system.
Q: Can I install water hammer arrestors myself?
A: While it is possible to install water hammer arrestors yourself, it is recommended to hire a professional plumber for the job. They have the knowledge and experience to ensure proper installation and placement of the arrestors.
Conclusion
Understanding the importance of water hammer arrestors is crucial for maintaining a healthy plumbing system. These devices play a vital role in preventing damage caused by water hammer, such as pipe bursts and leaks. By absorbing the shockwaves created by sudden changes in water flow, water hammer arrestors protect your pipes, fittings, and appliances from harm. So, if you’re experiencing water hammer in your plumbing system, consider installing water hammer arrestors to safeguard your investment and enjoy a quieter, worry-free home.
