MultiBox™ Washing Machine Outlet Box with Hammer Arresters

Product Description and Features

The Water-Tite MultiBox Washing Machine Outlet Box is configured for simple and secure installation, making it a reliable choice for contractors and homeowners. This single-box unit has multiple valve knockouts and two drains: one for a standard 2-inch washing machine drain and an optional 1-inch drain to pipe the box to the DWV (drain, waste, and vent) system. The supply valves come pre-installed and are durable forged brass with an anti-rotational design. They feature integrated hammer arresters that absorb sudden pressure changes to reduce stress on the plumbing system, providing continuous and maintenance-free protection against water hammer. This one-piece washing machine outlet box features integrated mounting flanges and can be installed more quickly than separate drain and valve boxes. It comes with a snap-on faceplate (6-1/2 inches wide by 6-7/8 inches high) that is interchangeable with all MultiBox outlet boxes and is able to accommodate up to two sheets of 5/8-inch drywall. The box has top and bottom stabilizer-bar slots and nail slots for optional extra support. Choose from a standard pack with an attached faceplate or a contractor pack with an unattached faceplate.
