Single-Lever Dual Drain Washing Machine Outlet Box.

IPS 85701 – Water-Tite DU-ALL Dual Drain Washing Machine Outlet Box with Integrated Arresters

The IPS 85701 Water-Tite DU-ALL Outlet Box is engineered for efficient water supply and drainage integration in residential and multifamily laundry installations. It includes dual drain ports and forward-mounted quarter-turn shutoff valves, as well as factory-installed hammer arresters to absorb pressure transients within the supply lines. Designed for versatility, this unit supports multiple configurations including left-drain, right-drain, dual-drain, and inverted top-entry installations.

With a single-piece box and frame design, this unit minimizes installation time and allows flexible positioning between wall studs. Snap-on faceplate compatibility and included brackets streamline rough-in work and facilitate consistent centerline positioning. Constructed from impact-resistant materials, the outlet box is suitable for new construction or renovation projects subject to frequent high-volume appliance use.

Installation Guidance

This box is designed for standard 16" OC wall stud spacing and allows for center alignment or offset positioning based on project layout. Inverted installation accommodates top-supply plumbing. Soldering may be required for sweat connections; installers must ensure valve orientation and support are secured per code. Drain alignment must be confirmed before wallboard closure.

Contractor Application

Job Site Considerations: The DU-ALL outlet box is frequently specified in multifamily housing and residential projects where integrated water hammer protection and flexible drain positioning are required. The unit's single-box format reduces inventory complexity and improves consistency across unit installations.

System Reliability and Protection

• ✅ Hydraulic Shock Absorption – Arresters eliminate the need for external devices, reducing installation labor and material costs.
• ✅ Service Accessibility – Forward-facing valve placement provides quick appliance isolation during service calls or emergencies.
• ✅ Drainage Efficiency – Compatible with standard 2" drains, supports code-compliant discharge from high-efficiency washers.
