Water hammer arrestors are crucial devices designed to protect plumbing systems from damaging pressure surges known as water hammer. However, like any other component, they can deteriorate over time, leading to potential issues. This blog post will provide a comprehensive guide on how to tell if a water hammer arrestor is bad, enabling homeowners and plumbers to identify and address malfunctioning units promptly.
Signs of a Bad Water Hammer Arrestor
1. Banging or Hammering Noises
The primary symptom of a faulty water hammer arrestor is the occurrence of loud banging or hammering noises within the plumbing system. These noises are caused by the sudden stop and start of water flow, resulting in pressure spikes that can damage pipes and fixtures.
2. Excessive Vibration
Malfunctioning water hammer arrestors can also cause excessive vibration in the plumbing system. As the water flow abruptly changes, it creates vibrations that can be felt throughout the pipes and fixtures.
3. Leaking
Leaking from a water hammer arrestor is another common indication of a malfunction. This can occur due to a damaged diaphragm or a loose connection. Water leaks can lead to water damage and increased water bills.
4. Reduced Water Pressure
A faulty water hammer arrestor can restrict water flow, resulting in reduced water pressure throughout the home. This can be particularly noticeable in fixtures that require higher water pressure, such as showers or washing machines.
5. Premature Failure of Fixtures
In severe cases, a malfunctioning water hammer arrestor can cause premature failure of plumbing fixtures and appliances. The pressure surges can damage valves, faucets, and other components, leading to costly repairs or replacements.
6. Water Hammer Noises Without Flow
If you hear water hammer noises even when no water is flowing, it could indicate a faulty check valve within the water hammer arrestor. The check valve prevents water from flowing back into the supply line when the water flow stops.
7. Visible Damage
In some cases, a bad water hammer arrestor may exhibit visible damage, such as dents, cracks, or corrosion. This damage can compromise the integrity of the unit and affect its ability to function properly.
Testing a Water Hammer Arrestor
To confirm the malfunction of a water hammer arrestor, you can perform the following simple test:
1. Turn off the main water supply to your home.
2. Open a faucet to release any remaining water pressure.
3. Locate the water hammer arrestor and tap it lightly with a hammer.
4. Turn the main water supply back on.
If you hear a loud banging noise when you tap the water hammer arrestor with the hammer, it indicates that the unit is not functioning properly and needs to be replaced.
Replacing a Water Hammer Arrestor
Replacing a faulty water hammer arrestor is a relatively straightforward task that can be performed by most homeowners with basic plumbing skills. Here are the steps involved:
1. Turn off the main water supply to your home.
2. Open a faucet to release any remaining water pressure.
3. Locate the water hammer arrestor and disconnect it from the plumbing system.
4. Install the new water hammer arrestor in the same location, ensuring it is oriented correctly.
5. Turn the main water supply back on and check for any leaks.
When to Call a Plumber
While replacing a water hammer arrestor is typically a simple task, it is advisable to contact a licensed plumber if you encounter any of the following situations:
- You are unsure about the location or orientation of the water hammer arrestor.
- The plumbing system is complex or inaccessible.
- You suspect there may be other underlying plumbing issues.
Wrapping Up
Water hammer arrestors are essential components for protecting plumbing systems from damaging pressure surges. By understanding the signs of a bad water hammer arrestor and following the steps outlined in this guide, you can effectively identify and resolve malfunctioning units, ensuring the longevity and functionality of your plumbing system.
