Are water hammer arrestors needed with PEX?
From an engineering standpoint, water hammer occurs when there is a conversion of energy. If a water distribution system is designed for a maximum flow rate of 8 ft./sec., you will never need a water hammer arrestor for CPVC or PEX tubing. So, if you only install CPVC or PEX tubing, you don’t have to read any further.
When would you use a hammer arrestor?
Water hammer arrestors are used to absorb the shock when water flowing in a piping system suddenly stops due to fast closing shutoff valves, dishwashers, and clothes washers. This action protects against annoying and potentially damaging effects of water hammer.
Why do I need a water hammer arrestor?
Install water hammer arrestors to prevent clanking pipes When a valve closes quickly and stops the flow, that momentum shakes and pounds pipes. A water hammer arrestor cures this condition with a cushion of air that absorbs the momentum.

1) Air Chambers − Where an air chamber is installed in a fixture supply, it shall be at least 12 inches in length and the same diameter as the fixture supply.
How long do mini arrestors last?
The air cushion in the arrester reacts instantly, absorbing the pressure spike that causes water hammer. Although arresters are typically tested to 10,000 cycles, Sioux Chief arresters have been independently lab tested to withstand 500,000 cycles without failure.
How do you test a water hammer arrestor?
You can test the water pressure by screwing a pressure gauge onto an exterior hose bib or behind the washing machine. The magic number is 75 psi—more than that, and you’ll want to call a professional to install or replace a pressure regulator.
