Water hammer arrestors are devices used to prevent the damaging effects of water hammer in plumbing systems. Water hammer occurs when water flow is suddenly interrupted or changed, causing a shock wave through the pipes. This shock wave creates a loud banging or hammering noise and can lead to damage to pipes, fittings, and other plumbing components. Water hammer arrestors are designed to absorb the shock wave and protect the plumbing system. However, some concerns have been raised about potential bursting of water hammer arrestors due to high pressure. This article aims to address whether a water hammer arrestor can burst from high pressure.
Understanding Water Hammer Arrestors:
Water hammer arrestors are typically installed near fixtures or appliances that are prone to causing water hammer, such as washing machines, dishwashers, or even in larger systems like multi-story buildings. These devices contain a chamber that is separated by a diaphragm or bladder, creating a cushion of air or gas that absorbs the shock wave generated by sudden water flow changes. The cushion compresses and decompresses as needed, preventing the pressure surge from traveling further through the system and protecting the pipes from damage.
The Pressure Limitations of Water Hammer Arrestors:
Water hammer arrestors are designed to operate within certain pressure limits to ensure their effective functioning while minimizing the risk of bursting. The pressure limits are typically indicated by the manufacturer and may vary depending on the specific model and type of water hammer arrestor. It is crucial to follow the manufacturer’s instructions and guidelines when selecting and installing water hammer arrestors to ensure they are suitable for the system’s pressure requirements.
Risk of Bursting Due to Excessive Pressure:
While water hammer arrestors are built to withstand high pressure to a certain extent, there is still a risk of bursting if the pressure exceeds their rated limits. Excessive pressure can cause the bladder or diaphragm to rupture, resulting in failure of the arrestor. Bursting can lead to water leakage, compromised functioning of the plumbing system, and potential damage to other components.
Preventing Bursting:
To prevent water hammer arrestors from bursting due to high pressure, it is essential to:
- Choose the right water hammer arrestor: Ensure that the arrestor selected is suitable for the system’s pressure requirements. Check the manufacturer’s specifications and consult professionals if needed.
- Install pressure regulators: Pressure regulators help control and maintain a safe pressure level in the plumbing system. Installing them before the water hammer arrestor can help prevent excessive pressure and reduce the risk of bursting.
- Regular maintenance: Regular inspection and maintenance of the water hammer arrestor are crucial. Check for any signs of wear, damage, or increased pressure. If any issues are detected, the arrestor should be replaced or repaired promptly.
While water hammer arrestors are effective in preventing the damaging effects of water hammer, they do have pressure limitations. If subjected to excessive pressure, they can indeed burst, leading to potential damage and malfunctioning of the plumbing system. It is crucial to select the right water hammer arrestor for the system’s pressure requirements, install pressure regulators if needed, and regularly maintain the arrestor to prevent bursting. Remember to consult professionals if there are concerns or uncertainties about the pressure limitations and appropriate use of water hammer arrestors.
