Did You Know?
1. The water hammer arrestor, also known as a “shock absorber for plumbing”, was first invented by British engineer, Thomas Allcock, in the late 1800s.
2. Water hammer arrestors are typically installed near appliances or plumbing fixtures that commonly cause water hammer, such as washing machines or dishwashers.
3. In addition to residential use, water hammer arrestors are commonly utilized in industrial settings, like factories or power plants, to protect larger plumbing systems from water hammer damage.
4. Water hammer arrestors work by absorbing the sudden surge of pressure that occurs when a water flow is abruptly halted, preventing the resultant banging or vibrating noises.
5. While water hammer arrestors are often installed in homes as a retrofit solution, newer plumbing codes now require their inclusion in new construction projects to prevent water hammer-related issues from the start.

Drain the system – Open all faucets and drain the water from the plumbing system. This will release any remaining pressure and make the installation process easier.
-
Choose the appropriate arrestor – Select a water hammer arrestor that matches the pipe size and water pressure of your plumbing system. Refer to the manufacturer’s instructions for guidance.
-
Install the arrestor – Attach the water hammer arrestor to the selected location. Use an adjustable wrench to tighten the connections securely. Apply Teflon tape to the threaded connections to ensure a watertight seal.
-
Make necessary modifications – If the existing pipes need to be modified to accommodate the water hammer arrestor, use a pipe cutter or hacksaw to make the necessary adjustments. Be careful to cut the pipes straight and clean any burrs or debris.
-
Test the system – After installing the water hammer arrestor, turn on the main water supply. Check for leaks and observe the water flow to ensure that the arrestor is functioning properly. If necessary, adjust the position or tighten the connections.
Tips For A Successful Water Hammer Arrestor Installation
To ensure a successful water hammer arrestor installation, keep the following tips in mind:

Frequently Asked Questions
Can a water hammer arrestor be installed in any direction?
Yes, a water hammer arrestor can be installed in any direction as needed. By hand screwing the water arrestor to the water stop valve and using a tee fitting for assistance when necessary, it allows for flexibility in installation. The arrestor can be positioned horizontally or vertically, depending on the specific requirements of the plumbing system. This adaptability ensures that the water hammer arrestor can effectively control pressure surges and minimize the potential for damage caused by water hammer.
Why install water hammer arrestor?
Installation of water hammer arrestors is essential to prevent damage caused by water hammer upstream of isolation valves. By fitting a hammer arrestor at the last pipe bend or elbow prior to the valve inlet, this device effectively mitigates the severity of water hammer. In instances of severe water hammer, multiple arrestors can be installed to distribute and minimize the impact throughout the entire system. This preventive measure not only safeguards the integrity of the plumbing system but also extends the lifespan of the valves by reducing the stress they experience during operation.
Can water hammer arrestors be installed in wall?
Yes, water hammer arrestors can indeed be installed in the wall. The water hammer arrestors mentioned earlier have been specifically designed for sealed wall installations and do not require an access panel. This means that they can be conveniently installed within the wall, providing a practical solution to control water hammer. By being able to place them within the wall, you can effectively address the issue of water hammer without any need for external components or panels.
Can you install hammer arrestor?
Hammer arrestors are highly recommended for installation in various areas of the home, including washers, dishwashers, and icemakers. However, they can also be installed for any fixture, such as the lav in the bathroom. To install a hammer arrestor in the lav, simply connect it between the 3/8″ outlet on a shutoff and the supply line leading to the faucet. This will effectively prevent water hammer and ensure a smooth and quiet water flow in the bathroom.
