Introduction: Understanding and Fixing Water Hammer – Linquip’s Expert Insights

Welcome to Linquip’s comprehensive guide on how to fix the water hammer in your plumbing system. As a leading platform that connects customers with industry professionals, we aim to provide accurate and reliable information on various home maintenance and repair topics. In this article, we’ll explore the causes of water hammers, how to identify them, and the steps to fix them.

 

What is Water Hammer?

A water hammer, also known as hydraulic shock, is a phenomenon where a sudden change in water flow causes a loud, banging noise within the pipes. This typically occurs when a faucet or valve is suddenly closed, causing a pressure wave to travel through the plumbing system. Over time, water hammers can damage pipes, valves, and fittings, leading to leaks and other issues.

 

Common Causes of Water Hammer

Some of the most common causes of water hammer include:

• High water pressure
• Quick-closing valves (e.g., washing machines and dishwashers)
• Air chambers or water hammer arrestors losing their air cushion
• Improper pipe installation or support

 

Signs and Symptoms of Water Hammer

Indicators of water hammer include:

• Loud banging or knocking sounds in pipes when water flow is stopped abruptly
• Rattling or vibrating pipes
• Leaks or damage to pipes, valves, and fittings

 

Step-by-Step Guide to Fixing Water Hammer

Follow these steps to fix the water hammer in your plumbing system:

1. Lower water pressure: High water pressure can exacerbate water hammer. Lower the pressure using a pressure-reducing valve or adjusting the main water shut-off valve.
2. Secure loose pipes: Ensure that all pipes are properly secured with appropriate pipe straps or supports.
3. Install water hammer arrestors: These devices provide an air cushion to absorb pressure surges and can be installed near quick-closing valves.
4. Drain the plumbing system: Turn off the main water supply and open all faucets to drain the water from the pipes. This can help replenish air chambers and restore their air cushion.
5. Check and repair damaged components: Inspect pipes, valves, and fittings for damage, and repair or replace them as needed.

 

Preventive Measures to Avoid Water Hammer

To prevent water hammers in the future, consider the following measures:

• Regularly check the water pressure and maintain it within the recommended range (40-60 psi)
• Install slow-closing valves or flow restrictors on appliances and fixtures
• Periodically drain the plumbing system to replenish air chambers
• Inspect and maintain pipes, valves, and fittings

 

When to Seek Professional Help

If you’re unable to fix the water hammer using the steps outlined in this guide or if the problem persists, it’s time to consult a professional plumber. A qualified plumber can accurately diagnose the issue and recommend appropriate solutions.

Types of Water Hammer Arrestors

There are various types of water hammer arrestors available to suit different plumbing systems and applications:

1. Piston-Type Arrestors: These arrestors feature a piston that moves within a chamber to absorb pressure surges. They are compact and can be installed horizontally or vertically.
2. Diaphragm-Type Arrestors: This type of arrestor uses a flexible diaphragm within a sealed chamber to absorb pressure surges. Diaphragm-type arrestors are suitable for residential and commercial applications and can be installed in any orientation.
3. Air Chamber Arrestors: These arrestors consist of a simple air-filled chamber that provides an air cushion to absorb pressure surges. They are typically installed vertically and require periodic draining to maintain their effectiveness.

 

Common Mistakes to Avoid When Fixing Water Hammer

Avoid these common mistakes when addressing water hammer issues:

1. Ignoring the problem: Water hammer should not be ignored, as it can cause significant damage to your plumbing system over time.
2. Over-tightening valves: Over-tightening valves when trying to stop the water hammer can lead to damage and make the issue worse.
3. Using makeshift solutions: Avoid using temporary fixes, such as wrapping pipes in insulation, as these solutions may not address the underlying problem and can lead to more significant issues in the long run.
4. Neglecting regular maintenance: Regularly inspecting and maintaining your plumbing system can help prevent water hammer and other problems.
