Water hammer is a common plumbing issue that occurs when there is a sudden increase or decrease in water pressure within the plumbing system. This can cause a loud banging or hammering noise, as well as potential damage to pipes, fittings, and fixtures. One question that often arises is whether water hammer can also cause a pulsating or irregular flow of water from faucets. In this article, we will explore the relationship between water hammer and pulsating faucet flow, as well as possible causes and solutions.
Understanding water hammer
To better understand whether water hammer can cause pulsating faucet flow, it’s important to first have a clear understanding of what water hammer is. Water hammer occurs when water is suddenly stopped or redirected in the plumbing system. This can happen when a valve is closed quickly, such as when a faucet or toilet is turned off, or when a water-using appliance like a washing machine or dishwasher stops using water. The sudden change in water flow creates a shock wave that travels through the pipes, causing them to vibrate and potentially leading to the loud banging or hammering noise associated with water hammer.
The connection to pulsating faucet flow
While water hammer is primarily known for its loud noises, it can indeed have an impact on faucet flow. When the shock wave from water hammer travels through the plumbing system, it can result in pressure fluctuations. These pressure fluctuations can cause water to flow unevenly from faucets, leading to a pulsating or irregular flow. The impact may be more noticeable in older plumbing systems with weaker pipes or fittings, but it can affect any plumbing system to some extent.
Causes of pulsating faucet flow
There are several potential causes of pulsating faucet flow resulting from water hammer. One common cause is the sudden closing of a valve, which can send a shock wave through the pipes. This can happen when a faucet is turned off too quickly or when a water-using appliance stops using water abruptly. Another possible cause is a faulty check valve or pressure regulator. When these components fail, they can allow sudden changes in water pressure that lead to pulsating faucet flow.
Solutions to prevent pulsating faucet flow
If you are experiencing pulsating faucet flow due to water hammer, there are several solutions you can consider. One of the most effective solutions is installing a water hammer arrestor. A water hammer arrestor is a device that absorbs the shock wave caused by sudden pressure changes and helps prevent it from reaching your faucets and other plumbing fixtures. By installing a water hammer arrestor at the source of the problem, you can minimize or eliminate pulsating faucet flow.
Additionally, you can take some preventive measures to avoid water hammer and its associated issues. Avoid turning faucets on or off too quickly, as this can create sudden pressure changes. Consider gradually reducing water flow before turning off faucets completely. Regular maintenance of your plumbing system, including checking and repairing faulty check valves or pressure regulators, can also help prevent pulsating faucet flow.
Water hammer can indeed cause pulsating faucet flow. The sudden pressure changes that occur during water hammer can lead to uneven water flow from faucets, resulting in a pulsating or irregular flow. To address this issue, installing a water hammer arrestor at the source of the problem is a recommended solution. Taking preventive measures and maintaining your plumbing system can also help prevent water hammer and its associated problems, including pulsating faucet flow.
