Water hammer is a common and often disruptive issue in residential plumbing systems. It is characterized by a loud banging noise when water flow is abruptly stopped, causing a shock wave through the pipes. This can lead to pipe damage, leaks, and a decrease in the lifespan of your plumbing system in O’Fallon, IL. At Polar, we emphasize the importance of preventing water hammers to maintain a quiet and efficient plumbing system. To help you avoid water hammers in your home or business, consider following the methods listed below throughout this blog. By implementing these tips, you can protect your plumbing and ensure its longevity.
Understanding Water Hammer
Before diving into prevention techniques, it is important to understand what causes water hammer. When a valve or faucet is quickly shut off, the moving water suddenly stops and creates a pressure wave. This wave travels back through the pipes, causing the banging noise that is often heard. The severity of the noise and the potential damage it can cause depend on the water pressure and the velocity at which the water is moving. Higher water pressure and faster-moving water result in more intense pressure waves, which can lead to more significant damage to the pipes, including leaks and bursts. Understanding this process is crucial for effective prevention.
Common Causes
Common causes of water hammer include the rapid closing of valves or faucets, high water pressure, and long, straight runs of pipe without adequate support. Quick-acting valves in washing machines or dishwashers are frequent culprits. Additionally, loose pipes can worsen the noise and potential damage as they move in response to the pressure wave. Improper pipe installation and lack of air chambers or water hammer arrestors can also contribute to the issue. Identifying these common causes is essential for implementing effective preventive measures and maintaining a quiet, efficient plumbing system.
Methods to Prevent Water Hammer
Water hammer can be a disruptive issue in residential plumbing systems, causing loud banging noises and potential damage to pipes. Fortunately, there are effective methods to prevent water hammer and maintain a quiet and efficient plumbing system. These preventive measures ensure a smoothly functioning plumbing system and minimize the risk of disruptive noise and damage.
Install Water Hammer Arrestors
One of the most effective ways to prevent water hammer is to install arrestors. These devices absorb the shock wave created by the sudden stoppage of water flow. They can be installed at various points in your plumbing system, such as near dishwashers, washing machines, and faucets. They contain a piston or air chamber that compresses to absorb the pressure wave, preventing it from causing noise or damage.
Reduce Water Pressure
High water pressure is a significant contributor to water hammer. Installing a pressure-reducing valve can help maintain your water pressure at a safe and consistent level. The ideal residential water pressure is typically between 40 and 60 psi (pounds per square inch). This will not only help prevent water hammer but also extend the life of your plumbing fixtures and reduce water consumption.
Secure Loose Pipes
Loose pipes can amplify the noise caused by a water hammer. Ensuring that all pipes are securely fastened to walls or floor joists can help reduce this noise. Use pipe clamps or straps to secure the pipes at regular intervals. Additionally, foam pipe insulation can be used to cushion the pipes and further reduce noise, providing a quieter and more stable plumbing system.
Install a Pressure Tank
In systems with a well, a pressure tank can help manage water pressure and prevent water hammer. The pressure tank acts as a buffer, absorbing fluctuations in pressure. It helps maintain consistent water pressure and reduces the likelihood of pressure waves forming when valves are closed. This not only prevents water hammering but also extends the lifespan of the plumbing system by minimizing stress on the pipes.
Check for Waterlogged Air Chambers
As mentioned earlier, air chambers can become waterlogged over time. Regularly check and maintain these chambers to ensure they remain effective. If you notice the water hammer returning, it may be time to drain the system and allow air to refill the chambers. Proper maintenance of air chambers is crucial to prevent water hammer and maintain a smoothly functioning plumbing system.
