A water hammer arrestor is a small, sealed cylinder that contains a cushion of air or gas. It is installed at the point of water hammer occurrence, such as near the washing machine, dishwasher, or other appliance causing the issue. The arrestor acts as a shock absorber, absorbing the pressure surge caused by the sudden water flow interruption. This helps minimize or eliminate the thudding noise and prevents potential damage to the plumbing system.
2. How to Install a Water Hammer Arrestor:
Installing a water hammer arrestor usually involves shutting off the water supply, draining the affected plumbing line, and attaching the arrestor between the supply line and the appliance causing the water hammer. The arrestor must be positioned in an upright position, as indicated in the manufacturer’s instructions, to ensure it functions effectively.
3. Other Potential Solutions:
If a water hammer repair kit does not completely resolve the issue, there might be other underlying causes for the problem. Loose pipes, incorrectly positioned valves, or excessive water pressure can also contribute to water hammering. In such cases, it is advisable to consult a professional plumber to accurately diagnose and rectify the root cause.
Water hammers can cause significant disturbances and potential damage to a plumbing system if left unaddressed. While repair kits, particularly those containing water hammer arrestors, can effectively resolve many cases of water hammering, there may be situations where a thorough inspection by a professional plumber is necessary. Remember, preventing water hammers through regular maintenance, correctly installed valves, and appropriate pressure control can help eliminate the need for repair kits and protect your plumbing system from long-term damage.
