Ever hear a loud banging noise from your pipes after turning off a tap? That noise is water hammer, a common plumbing problem that can be more than just a nuisance—it can potentially damage your plumbing system. But don’t worry! We can help you prevent or fix water hammer problems.
What Causes Water Hammer?
Water hammer occurs when a water valve is suddenly shut off, causing a shockwave that makes the pipes bang against walls or each other. This can happen in washing machines, dishwashers, toilets, and sinks. As mentioned, the most common sign of water hammer is a loud banging or thumping sound from your pipes. This noise typically occurs right after turning off a water tap or when a water-using appliance stops its cycle. It sounds like a hammering noise and is distinct from normal water flow noises. Additionally, you might notice vibrations in your pipes or see them visibly shaking due to the pressure surge.
Are Certain Homes or Businesses More Prone to Water Hammer?
Certain homes are more prone to experiencing water hammer, particularly older ones with outdated plumbing systems that may not include modern water hammer prevention devices, such as air chambers or arrestors. Homes with high water pressure are also more susceptible, as higher pressure can lead to more forceful water hammer impacts. However, it’s important to note that water hammer can occur in any home, regardless of age or design.
Water hammer can also occur in commercial and industrial buildings. Large-scale systems, such as factories, municipal water supplies, and power plants, are also susceptible to water hammer. In all of these settings, the potential for damage can be significant, necessitating specialized water hammer mitigation strategies.
Damage Caused by Water Hammer
Water hammer can cause significant damage to plumbing systems over time. The sudden pressure surges it creates can strain pipes, leading to loosened joints, leaks, or even bursts. This is particularly concerning in older or weaker piping systems. Repeated water hammer incidents can also damage appliances connected to the plumbing system, such as washing machines and dishwashers, by stressing their internal components.
Water hammer can affect appliances like washing machines and dishwashers, as well. These appliances often have solenoid valves that open and close quickly, which can trigger water hammer. Additionally, the repeated pressure surges associated with water hammer can strain and damage the internal components of these appliances, potentially leading to malfunctions and the need for repairs. Installing water hammer arrestors can help protect the plumbing system and connected appliances.
What Can be Done About Water Hammer?
Water hammer can be mitigated, in the following ways. Please contact professionals, such as the expert plumbers at Liberty Plumbing, for assistance!
- Reduce Water Pressure: High water pressure can exacerbate water hammer because it increases the velocity of water flowing through the pipes. When a valve is suddenly closed, the momentum of the fast-moving water creates a more forceful and higher-pressure surge. This intensified surge can cause louder banging noises and increase the risk of damage to the plumbing system. That is why keeping your home’s water pressure between 30 and 50 psi is advisable.
- Install Air Chambers: One of the most effective solutions is adding air chambers and vertical pipes to your plumbing system. They act as cushions, absorbing the shock wave created when the water flow is abruptly stopped. You’ll often find these near faucets or water-using appliances.
- Check for Loose Pipes: Sometimes, the simple act of securing loose pipes can mitigate water hammer. Ensure your pipes are firmly attached with pipe straps or hangers, which can be easily installed.
- Open and Close Valves Slowly: A simple yet effective tip is to open and close valves gently. By avoiding sudden stops in water flow, you can significantly reduce the chances of water hammer.
- Regular Maintenance: Regular maintenance by a professional plumber can help identify and resolve potential water hammer issues before they become serious problems.
