Dual Drain Washing Machine Outlet Box with Single-Lever Control Valves.

IPS W2800 – Water-Tite DU-ALL Dual Drain Washing Machine Outlet Box

The Water-Tite DU-ALL outlet box (Model W2800) is a single-piece washing machine outlet solution engineered for dual-drain applications in residential and multi-unit construction. Designed for professional-grade performance, the unit integrates supply valve control and drainage within a compact molded enclosure for simplified installation and long-term reliability.

This model allows for flexible configurations, including dual-drain, left- or right-drain-only, and top-inverted valve mounting. Forward-facing valves improve accessibility during shutoff and maintenance, while structural features support stable wall integration and protection against incidental leaks.
