Water hammer occurs when the flow of moving water is suddenly stopped by a closing valve. Without proper protection, this shock can damage expensive fixtures and appliances throughout your plumbing system, leading to fractured pipe joints, leaking valves, burst laundry hoses, and premature failure of water heaters. The Sioux Chief 660-H Mini-Rester Water Hammer Arrester Tee prevents these costly failures by absorbing the shock that causes water hammer noise and pressure spikes.
This tee-style arrester connects directly to washing machine supply valves or installs in-line near problem valves and fixtures. Its compact design is ASSE-certified for sealed wall installations with no access panel required, and it can be installed at any angle for maximum flexibility in your plumbing layout.
