The Best Water Hammer Arrestors

What's In This Guide?

      What Is a Water Hammer Arrestor?

      A water hammer arrestor absorbs the hydraulic shock caused by a quick closing valve in your piping system, known as a water hammer. Noisy pipes indicate that you have a water hammer. 

      A water hammer may occur due to a faulty valve or improper installation of a faucet or appliance. It can also happen if you increase the water pressure entering your home from the main water line or your water heater.

      did you know water hammer arrestor

      The water hammer effect can cause loose pipes that bang into each other, causing damage to the pipe material. A water hammer can also create excessive pressure levels inside your pipes, which is also a potential cause of damage to your pipes.

      A component in the T-shape water hammer arrestor absorbs the shock wave to prevent excessive amounts of pressure that creates noise or causes damage to the plumbing material. According to residential building codes, all objects solenoid valves require a water hammer arrestor.

      Water hammer arrestors attach to the cold and hot water lines of a faucet or appliance, such as a washing machine.

      Different Types of Hammer Arresters

      Piston Water Hammer Arrestors 

      Most water hammer arrestors use pistons to absorb the shock wave caused by a quick-closing valve. Water hammer arrestors that use pistons are the most effective option.

      Non-Piston Water Hammer Arrestors

      Non-piston water hammer arrestors don’t use pistons. Instead, they use a simple air chamber to absorb the shock. 

      What to Look For In the Best Water Hammer Arrestor

      Size 

      You need to find a water hammer arrestor that fits the appropriate fixture. Connections vary based on the type of fixture and its location. The most common sizes you will find include ½” and ¾”. 

      Material

      The best water hammer arrestors consist of high-end materials, such as brass, copper, and 304 stainless steel. However, you may also find products made from plastic.

      You will also need to find an arrestor that can withstand the heat and pressure requirements of the particular faucet or appliance.

      Install it as close to the faucet or appliance as possible between the shut-off valve and the water supply.
