Sioux Chief 660-V82B Water Hammer Arrester 1/2 in Cpvc

Product Description

The SIOUX CHIEF 660-V82B is a Size AA Mini-Rester water hammer arrester designed to eliminate pipe shock and pressure surges in residential plumbing systems. It installs on 1/2-inch CPVC male connections and absorbs the hydraulic shock wave that occurs when fast-closing valves, solenoids, or appliance inlet valves shut off flow abruptly. The piston-style cushioning chamber prevents the banging, rattling, and pipe stress associated with water hammer. This unit is sized and rated for residential supply lines and is installed by licensed plumbers or qualified mechanical contractors.

The 660-V82B is suited for residential applications where 1/2-inch CPVC supply lines feed washing machines, dishwashers, ice makers, or other appliances with solenoid-controlled valves. The Size AA designation corresponds to a specific flow and pressure range defined by the Plumbing and Drainage Institute (PDI) standard WH-201, making it appropriate for single fixture or appliance branch lines in homes and light-duty residential construction.

Key Features

• Size AA PDI rating suited for single-fixture residential branch line installations
• 1/2-inch CPVC male connection for direct integration into CPVC supply runs
• Piston-type internal mechanism absorbs hydraulic shock without air-bladder degradation over time
• Compact mini form factor fits in tight spaces behind appliances and inside wall cavities
• Compatible with standard residential water supply pressures

Compatibility

Designed as an OEM-style replacement or new-installation water hammer arrester for residential plumbing systems using 1/2-inch CPVC male supply connections, rated Size AA per PDI WH-201.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Shut off the water supply and relieve line pressure before making any connections. Apply the appropriate solvent cement for CPVC joints per manufacturer and code requirements, and allow full cure time before restoring pressure. Do not overtighten or use the arrester as a structural anchor for adjacent piping.
