Buying Guide for Best Water Hammer Arrestor For Pex

What is a Water Hammer Arrestor?
A water hammer arrestor is a device that prevents water hammer, which is the banging noise that happens when water flow stops abruptly. It works by allowing water pressure to increase gradually so that when it stops flowing, the pressure remains at a constant level. This eliminates the shockwave created by an abrupt stop in water flow.

How Does a Water Hammer Arrestor Work?
A water hammer arrestor works by introducing air into the pipe system and allowing it to compress as the flow of water increases or decreases. The air acts as a cushion, absorbing the shockwave created by an abrupt change in pressure. This prevents loud banging noises and keeps the pipes from being damaged by high pressure or suction forces.

Types of Water Hammer Arrestors
There are two types of water hammer arrestors: mechanical and hydraulic. Mechanical arrestors are installed in the pipe line and contain a piston that compresses air when there is an abrupt change in pressure. Hydraulic arrestors are installed outside of the pipe line and use air chambers to absorb shockwaves created by changes in pressure.

Best Water Hammer Arrestor for Pex
The best water hammer arrestor for Pex piping is one that combines both mechanical and hydraulic components. These systems typically feature an adjustable piston inside of a chamber filled with air, along with an external chamber for additional protection against sudden changes in pressure. The adjustable piston helps ensure that only enough air is compressed to absorb shockwaves without creating too much resistance on the pipe system. In addition, these systems typically come with additional features such as temperature sensors and alarms to alert you when there has been an abrupt change in pressure or temperature.

Factors to Consider When Buying a Water Hammer Arrestor
When buying a water hammer arrestor, it’s important to consider factors such as size, installation requirements, and cost. The size of your pipes will determine what type of arrestor you need, while installation requirements will vary depending on whether you need to install it inside or outside of your plumbing system. Finally, cost should also be taken into consideration since some models may be more expensive than others depending on their features and performance ratings.

The best water hammer arrestor for PEX is the Watts LF25AUB-Z3. It is designed to protect PEX piping systems from the damaging effects of water hammer, and it is easy to install. It has a stainless steel construction and a large capacity tank, so it will last for many years. It also comes with an adjustable pressure relief valve that helps regulate the pressure in your system. The Watts LF25AUB-Z3 is an excellent choice for anyone looking for a reliable water hammer arrestor for their PEX piping system.
