What To Know
- Water hammer arrestors are designed to mitigate the effects of water hammer by absorbing the excess pressure and gradually releasing it back into the plumbing system.
- Spring-loaded arrestors use a spring to apply pressure on a piston, which closes against a seat to prevent backflow and absorb pressure surges.
- The type of water hammer arrestor you need depends on several factors, including the size and type of plumbing system, the severity of the water hammer problem, and the specific application.
Water hammer arrestors, often overlooked but invaluable plumbing components, play a crucial role in protecting your home’s plumbing system from the damaging effects of water hammer. This article will delve into the intricate world of water hammer arrestors, exploring their purpose, types, installation, and maintenance, empowering you to safeguard your plumbing and prevent costly repairs.
What is Water Hammer?
Water hammer, also known as hydraulic shock, occurs when a fast-moving stream of water is abruptly halted, creating a surge of pressure that can damage pipes, fixtures, and appliances. This phenomenon is common in plumbing systems when faucets are quickly shut off, valves are closed, or water-using appliances like washing machines or dishwashers complete their cycles.
The Role of Water Hammer Arrestors
Water hammer arrestors are designed to mitigate the effects of water hammer by absorbing the excess pressure and gradually releasing it back into the plumbing system. They act as safety valves, preventing the damaging pressure surge from traveling through the pipes and causing harm.
Types of Water Hammer Arrestors
There are various types of water hammer arrestors available, each with its own unique characteristics:
- Air Chamber Arrestors: These arrestors use a compressed air chamber to absorb pressure surges. They are commonly found in residential plumbing systems.
- Diaphragm Arrestors: Diaphragm arrestors employ a flexible diaphragm to separate water from a compressed air chamber. They are suitable for both residential and commercial applications.
- Spring-Loaded Arrestors: Spring-loaded arrestors use a spring to apply pressure on a piston, which closes against a seat to prevent backflow and absorb pressure surges. They are often used in industrial settings.
- Water Column Arrestors: Water column arrestors utilize a vertical column of water to absorb pressure surges. They are commonly found in high-rise buildings.
Choosing the Right Water Hammer Arrestor
The type of water hammer arrestor you need depends on several factors, including the size and type of plumbing system, the severity of the water hammer problem, and the specific application. Consider consulting with a qualified plumber to determine the most appropriate option for your needs.
Installing Water Hammer Arrestors
Proper installation is crucial for the effective performance of water hammer arrestors. Here are some general guidelines:
- Install arrestors as close as possible to the source of the water hammer problem, such as near faucets or appliances.
- Orient the arrestor vertically, with the arrow on the body indicating the direction of water flow.
- Use a pipe wrench to tighten the arrestor securely to the plumbing system.
- Ensure that the arrestor is not overtightened, as this can damage the threads.
Maintaining Water Hammer Arrestors
Regular maintenance is essential to ensure the longevity and effectiveness of water hammer arrestors. Here’s how you can maintain them:
- Check the arrestors for any leaks or damage periodically.
- If an arrestor is leaking, replace it immediately.
- For air chamber arrestors, check the air pressure every few months and adjust it if necessary.
- For diaphragm arrestors, inspect the diaphragm for any signs of wear or damage.
Signs of Water Hammer Problems
If you suspect that your plumbing system is experiencing water hammer, look for these signs:
- Loud banging or knocking sounds when faucets are shut off
- Loose or vibrating pipes
- Leaking faucets or valves
- Damaged appliances like washing machines or dishwashers
Benefits of Using Water Hammer Arrestors
Installing water hammer arrestors offers several benefits:
- Prevents damage to pipes, fixtures, and appliances
- Reduces noise and vibration in the plumbing system
- Extends the lifespan of plumbing components
- Improves overall plumbing performance
Conclusion: Safeguarding Your Plumbing with Water Hammer Arrestors
Water hammer arrestors are indispensable plumbing components that protect your home’s plumbing system from the damaging effects of water hammer. By understanding the types, installation, and maintenance of water hammer arrestors, you can safeguard your pipes, fixtures, and appliances, ensuring a trouble-free and long-lasting plumbing experience.
