Where to Use the Watts 05-3-8 Arrestor

The Watts Series 05 Mini Water Hammer Arrestor is designed for residential and light commercial applications where quick-closing valves create pressure shock. Ideal installation points include supply lines to dishwashers, clothes washers, ice makers, and any quick-closing solenoid valve or faucet. The compact 3/8" NPT connection makes it perfect for tight spaces and concealed installations behind appliances or inside walls. Install with a standard tee fitting on hot or cold water lines wherever sudden valve closure causes banging pipes or pressure spikes. Compatible with copper, PEX, CPVC, and other standard plumbing materials when proper adapters are used.

💧 Pro Tip: Water hammer arrestors work by absorbing pressure spikes with a cushion of air. The Watts 05 series is factory-charged and sealed, so it requires no maintenance or recharging. Install as close as possible to the fixture or appliance causing the water hammer for maximum effectiveness.
