Water Hammer Arresters: What Are They and Why Are They Important?
If you've ever heard a loud banging noise when you turn off a faucet or shut off a washing machine, you may have experienced water hammer. Water hammer is a common problem in plumbing systems that can lead to damage to pipes and fixtures over time. Fortunately, water hammer arresters can help prevent this problem. In this article, we'll take a closer look at water hammer arresters and their importance in modern plumbing systems.
What Are Water Hammer Arresters?
Water hammer arresters are devices that are installed in plumbing systems to prevent the sudden pressure spikes that cause water hammer. The device contains a piston or diaphragm that compresses air or gas as water flows through the system. When the water flow is suddenly stopped, the compressed air or gas absorbs the shock, preventing the pressure spike that causes water hammer.
Water hammer arresters can be installed at the point where the water supply enters a fixture or appliance, such as a washing machine or dishwasher, or at the main water supply line to the building. They come in different sizes and configurations, depending on the specific application.
Why Are Water Hammer Arresters Important?
Water hammer can cause damage to pipes, fittings, and fixtures over time. The repeated shock of the pressure spikes can cause joints to loosen, pipes to rupture, and fixtures to break. Over time, the damage can lead to leaks, water damage, and costly repairs.
Water hammer arresters are important because they prevent the pressure spikes that cause water hammer, protecting the plumbing system and its components from damage. They also improve the lifespan of fixtures and appliances, reducing the need for frequent repairs and replacements.
How to Install and Maintain Water Hammer Arresters
Installing water hammer arresters is best left to a licensed plumber or contractor. The device must be installed at the correct location and orientation to work properly. If installed incorrectly, the water hammer arrester may not function as intended or may even cause more problems.
Maintaining water hammer arresters is relatively easy. The device should be inspected periodically for signs of damage or leaks. If the device is leaking or damaged, it should be replaced as soon as possible to prevent water hammer from occurring.
In conclusion, water hammer arresters are an essential component of modern plumbing systems. They prevent the sudden pressure spikes that cause water hammer, protecting pipes, fittings, and fixtures from damage. By understanding the importance of water hammer arresters and how to install and maintain them, homeowners and plumbers can ensure that their plumbing systems are reliable and long-lasting.
