Product Overview

The Water-Tite DU-ALL Dual-Drain Washing Machine Outlet Box features an innovative design that offers multiple valve mounting options. Choose from dual-drain, right-drain-only, and left-drain-only installations, or invert the box for top-mount valves with a center drain. This outlet box features valves with integrated hammer arresters that absorb sudden pressure changes to reduce stress on the plumbing system, providing continuous and maintenance-free protection against water hammer. Forward-mounted valves give homeowners easy access to on/off controls, while the drains are positioned toward the back of the box. A raised drip guard contains and sends hose or valve leaks directly down the drain instead of onto the laundry room wall and floor. The EZ Out test caps are raised for quick removal, and the knockouts are oversized, so they won't fall down the drain. Featuring a one-piece design, this washing machine outlet box can be installed more quickly than separate drain and valve boxes. The box rests securely against the back sheetrock and includes two mounting brackets for attachment to the studs for sturdy installation. It comes with a snap-on faceplate (10-3/16 inches wide by 8-13/16 inches high) that is interchangeable with center-drain outlet-box faceplates. Choose from a standard pack with an attached faceplate or a contractor pack with an unattached faceplate.
