Dealing with plumbing noises like banging or knocking in your pipes can be frustrating. This phenomenon is often referred to as “water hammer” and it occurs when water suddenly stops or changes direction. To address this issue effectively, a water hammer arrestor can be installed. These devices are designed to dampen the shock waves in your plumbing system and eliminate unwanted noise.
Understanding How a Water Hammer Arrestor Works
A water hammer arrestor functions as a cushion for the jolt caused by sudden water stoppage or redirection. Typically, it contains a piston or a diaphragm that absorbs the kinetic energy, thus reducing pressure changes. Proper installation can greatly improve the longevity and safety of your home’s plumbing.
Choosing the right water hammer arrestor for your system depends on several factors, including pipe size and water pressure levels. By installing these devices strategically, ideally at the point where the noise originates, you can ensure smooth and quiet operation of your plumbing system.
Steps to Install a Water Hammer Arrestor
Installing a water hammer arrestor can be done as a DIY project or with the help of a professional plumber. Here are the general steps to follow:
- Shut off the water supply: Begin by turning off the main water valve and open the faucets to drain any water from the pipes.
- Identify the problem areas: The best place to install an arrestor is near appliances like dishwashers or washing machines that frequently cause water hammer.
- Cut into the pipe: Use a pipe cutter to carefully cut into the pipe at your chosen location. Ensure that the space is dry and clean before proceeding.
- Insert the water hammer arrestor: Attach the arrestor to the pipe using the correct fittings. Be sure the arrestor is compatible with your pipe type, whether it is PVC, copper, or steel.
- Secure the fittings: Use joint compound or pipe tape to secure the connections and prevent leaks.
After installation, turn the water supply back on and check for any leaks around the fittings. Make adjustments as necessary to ensure a snug fit.
Maintenance and Care for Water Hammer Arrestors
While water hammer arrestors require minimal maintenance, regular checks can ensure their effective performance. Inspect them periodically for signs of wear or leaks, especially after an increase in water pressure or changes in the plumbing system. If you notice consistent noise or jarring movements in the system, it might be time to inspect and possibly replace the existing arrestors.
Replacing an arrestor is straightforward if you follow the same installation steps. Always ensure you have the compatible model and specifications for your specific plumbing needs.
Benefits of Using Water Hammer Arrestors
Incorporating water hammer arrestors into your plumbing system offers several advantages:
- Reduces noise and banging in the pipes, providing a quieter environment.
- Prevents damage to the plumbing system due to high-pressure surges, extending its lifespan.
- Improves the efficiency and performance of water-related appliances.
