Water hammer is a common plumbing phenomenon where sudden pressure surges occur within the pipes, resulting in a banging or juddering sound. This occurrence can not only be irritating but can also damage the plumbing system if left unresolved. There are various methods to mitigate water hammer, the most common being the installation of water hammer arrestors. However, some individuals may question whether replacing pipes entirely can be a permanent solution to this issue. In this article, we will delve into the effectiveness of pipe replacement in permanently resolving juddering caused by water hammer.
Understanding Water Hammer:
Before discussing the potential permanent resolution, it is essential to understand the root cause of water hammer. Water hammer occurs when the flow of water within the pipes is abruptly halted, causing a surge of pressure and resulting in vibrations or juddering. This can happen when, for example, a faucet or valve is closed too quickly, causing the water to abruptly stop in its path. Additionally, inadequate pipe installation or improper pipe material can exacerbate the occurrence of water hammer.
The Role of Water Hammer Arrestors:
Water hammer arrestors are devices specially designed to mitigate the effects of water hammer. These devices consist of a sealed air chamber that absorbs the pressure surge caused by sudden changes in water flow. When installed, the water hammer arrestors act as a cushion, absorb the shockwave, and prevent juddering, thus reducing the strain on the plumbing system. While water hammer arrestors can be an effective solution for many cases, they may not always provide a permanent resolution, depending on the underlying issue.
Replacing Pipes as a Permanent Solution:
1. Identifying the underlying issue:
To determine if replacing pipes can permanently resolve juddering, it is essential to identify the root cause of the water hammer. If the problem lies solely in the design or installation of the pipes, replacing them with properly sized and installed pipes can indeed resolve the issue permanently. In such instances, the pipes may be too small, causing water to flow at high velocities, or inadequately secured, leading to vibrations and juddering.
2. Upgrading pipe material:
In some cases, water hammer may occur due to the use of outdated or inappropriate pipe materials. Older pipes made of materials such as galvanized steel or iron can contribute to the occurrence of water hammer. By upgrading to modern pipe materials, such as copper or PEX, which have better shock-absorbing properties and increased flexibility, the chances of juddering can be significantly reduced.
3. Considering pipe sizing and water pressure:
Proper pipe sizing is crucial to ensure a smooth flow of water and prevent water hammer. If the pipes are undersized or the water pressure is too high, the risk of water hammer increases. Replacing pipes with appropriately sized ones, along with adjusting water pressure, can help prevent juddering and eliminate the need for frequent repairs or the use of water hammer arrestors.
While water hammer arrestors are effective in mitigating the effects of water hammer, they may not provide a permanent solution for everyone. Replacing pipes can be a viable option for those experiencing persistent juddering due to water hammer, especially when the underlying issue lies in pipe design, installation, material, or sizing. By addressing these concerns and implementing appropriate changes, individuals can enjoy a plumbing system free from the bothersome and potentially damaging effects of water hammer. Consulting a professional plumber can provide further guidance and assistance in determining the best course of action based on the specific plumbing system.
