How to Avoid Water Hammer in Your Pipes

Water hammer is a common but often overlooked plumbing issue that can cause significant damage to your home’s plumbing system. Characterised by a loud banging or thudding noise when you quickly shut off a faucet or valve, water hammer occurs when the flow of water suddenly stops, creating a shockwave that travels through the pipes. Over time, this can lead to damaged pipes, leaks, and other costly repairs. Fortunately, there are several effective ways to prevent and mitigate water hammer in your home’s plumbing system. This article will explore what causes water hammer, its potential impacts, and practical steps you can take to avoid it.

Understanding Water Hammer

To prevent water hammer, it’s essential to understand what it is and how it happens. Water hammer occurs when water flowing at high speed is suddenly forced to stop or change direction. This abrupt change in velocity creates a pressure surge, resulting in a shockwave that reverberates through the pipes. The sound you hear is the pipe vibrating or banging against a wall or another solid object.

Common causes of water hammer include:

Quickly Closing Valves or Faucets: When a valve or faucet is shut off rapidly, the water flow is suddenly halted, causing the pressure surge that leads to water hammer.

High Water Pressure: Excessively high water pressure can increase the velocity of water in your pipes, making your system more prone to water hammer.

Faulty or Worn Out Valves: Valves that don’t close properly or are worn out can cause irregular water flow, contributing to water hammer.

Long Pipe Runs or Improperly Secured Pipes: Long runs of pipe or pipes that are not securely fastened can exacerbate the effects of water hammer, as the pipes have more room to vibrate or move.

The Potential Impacts of Water Hammer

While the noise of water hammer can be annoying, the potential damage it can cause is far more concerning. Over time, repeated water hammer can lead to:

Damaged Pipes: The repeated stress from water hammer can weaken pipes, causing them to crack, leak, or even burst in severe cases.

Loose or Broken Pipe Fittings: The vibrations from water hammer can loosen or break pipe fittings, leading to leaks or disconnections.

Damage to Appliances: Water hammer can also harm appliances connected to your plumbing system, such as washing machines, dishwashers, and water heaters, by subjecting them to sudden pressure surges.

Water Leaks: Leaks caused by damaged pipes or fittings can lead to water damage in your home, including mold growth, rot, and structural issues.

How to Prevent and Fix Water Hammer

Preventing and fixing water hammer involves addressing the root causes and ensuring your plumbing system is designed to handle sudden changes in water pressure. Here are some effective strategies to avoid water hammer in your home:

Install Water Hammer ArrestorsWater hammer arrestors are devices specifically designed to absorb the shockwave caused by water hammer. They contain a cushion of air or gas that compresses when a pressure surge occurs, preventing the shockwave from traveling through the pipes. Water hammer arrestors can be installed near appliances or fixtures prone to water hammer, such as washing machines, dishwashers, or any other device with quick-closing valves.

Use Slow-Closing ValvesReplacing standard valves with slow-closing or anti-water hammer valves can significantly reduce the risk of water hammer. These valves close more gradually, giving the water flow time to slow down before coming to a complete stop, thus preventing the sudden pressure surge that causes water hammer.

Lower Your Water PressureHigh water pressure is a major contributor to water hammer. You can reduce your water pressure by adjusting the pressure regulator on your main water line. Most homes have a pressure regulator set to a standard range of 40 to 60 psi. If your water pressure is above this range, lowering it can help reduce the likelihood of water hammer. A plumber Fulham can assist with adjusting the pressure regulator if needed.

Install Air ChambersAir chambers are simple devices installed in your plumbing system to absorb the shock of water hammer. They are essentially vertical pipes capped at the top and filled with air. When a valve is closed quickly, the air in the chamber compresses, absorbing the shockwave and preventing it from traveling through the pipes. Air chambers should be installed near fixtures where water hammer is a problem. However, over time, air chambers can fill with water and lose their effectiveness, so they may need to be drained periodically to restore their function.

Secure Loose PipesPipes that are not securely fastened can move or vibrate when water hammer occurs, amplifying the noise and potential damage. Ensuring that all pipes are properly secured with brackets, clamps, or hangers can help reduce movement and mitigate the effects of water hammer. If you have access to the pipes, such as in a basement or crawl space, check for any loose or improperly supported sections and secure them as needed.

Shorten Long Pipe RunsLong runs of pipe can increase the impact of water hammer. If possible, consider rerouting or shortening long sections of piping to reduce the distance the shockwave can travel. This may involve hiring a plumber to redesign parts of your plumbing system, especially in older homes where the plumbing may not have been installed with water hammer prevention in mind.

Upgrade to Modern Piping MaterialsOlder homes may have plumbing systems made from materials that are more susceptible to water hammer, such as galvanized steel. Upgrading to modern materials like PEX or copper, which are more flexible and resistant to pressure surges, can help reduce the risk of water hammer. While this is a more involved and costly solution, it can provide long-term benefits in terms of both preventing water hammer and improving overall plumbing performance.

When to Call a Professional

While many solutions for water hammer can be implemented by a knowledgeable DIYer, some situations may require the expertise of a professional plumber. If you’ve tried the above methods and are still experiencing water hammer, or if you’re unsure about how to proceed, it’s best to consult with a plumber. They can accurately diagnose the cause of the water hammer and recommend the most effective solution, whether it’s installing water hammer arrestors, adjusting your water pressure, or upgrading your plumbing system.

Conclusion

Water hammer may start as a minor nuisance, but if left unaddressed, it can lead to significant damage and costly repairs. By understanding the causes of water hammer and taking proactive steps to prevent it, you can protect your home’s plumbing system and avoid the disruptions and expenses that come with this common issue. Whether through installing water hammer arrestors, securing loose pipes, or lowering your water pressure, there are multiple ways to safeguard your plumbing system against the damaging effects of water hammer. If you’re experiencing water hammer and are unsure how to fix it, don’t hesitate to seek professional help to ensure your home’s plumbing remains in top condition.
