Banish the Hydraulic Shock: Easy Instructions on Installing a Water Hammer Arrestor for Your Refrigerator

A water hammer arrester, also known as a water hammer suppressor or shock absorber, is a device installed in plumbing systems to prevent water hammer. Water hammer is a phenomenon that occurs when water flow in pipes is suddenly stopped, creating a pressure surge that can damage pipes, appliances, and fixtures.

Why Install a Water Hammer Arrester on a Refrigerator?

Refrigerators require a constant supply of water for ice making and water dispensing. When the water supply is turned off or the refrigerator is turned off, the sudden stop of water flow can create a water hammer. This can damage the refrigerator’s water line, valves, and other components.

Materials Required

• Water hammer arrester
• Adjustable wrench
• Teflon tape
• Plumber’s putty (optional)

Step-by-Step Installation Guide

1. Turn off the Water Supply: Shut off the water valve that supplies water to the refrigerator.
2. Locate the Water Line: Identify the water line that connects to the refrigerator.
3. Cut the Water Line: Using an adjustable wrench, cut the water line approximately 6 inches from the refrigerator’s water inlet valve.
4. Apply Teflon Tape: Wrap several layers of Teflon tape around the threads of the water hammer arrester’s inlet and outlet connections.
5. Install the Water Hammer Arrester: Screw the water hammer arrester into the cut water line, ensuring that the arrow on the arrester points in the direction of water flow (towards the refrigerator).
6. Reconnect the Water Line: Screw the other end of the water line onto the water hammer arrester‘s outlet connection.
7. Turn on the Water Supply: Slowly turn on the water valve to allow water to flow through the system.
8. Check for Leaks: Inspect all connections for leaks. If any leaks are detected, tighten the connections further or apply plumber‘s putty around the base of the water hammer arrester.

Troubleshooting Common Issues

• No Water Flow: Ensure that the water supply is turned on and that the water hammer arrester is installed correctly with the arrow pointing in the direction of water flow.
• Water Leaks: Tighten the connections on the water hammer arrester and the water line. If leaks persist, replace the water hammer arrester.
• Loud Noises: If the water hammer arrester makes loud noises, it may be faulty. Replace the arrester with a new one.
• Frozen Water Hammer Arrester: If the water hammer arrester freezes during cold weather, wrap it in insulation or heat tape to prevent freezing.

Maintenance and Replacement

Water hammer arresters should be inspected and replaced every 5-10 years or as needed. If you experience any issues with water hammer, check the arrester first and replace it if necessary.

Final Thoughts

Installing a water hammer arrester on your refrigerator is a simple and effective way to protect your appliance and plumbing system from the damaging effects of water hammer. By following these steps, you can ensure a trouble-free water supply for your refrigerator.
