EFIELD Premium Laundry Box WM028
The WM028 model is designed for PEX-based systems with a 1/2-inch barb crimp inlet and a 3/4-inch MHT outlet. It ships with 1/4-turn hot and cold ball valves and stainless steel water hammer arrestors, providing durable protection against pressure surges. This unit comes direct from a major PEX manufacturer, offering a reliable, factory-supported option for retrofit or new installs. Consider this box if your laundry plumbing uses crimp PEX fittings and you want integrated surge protection without extra components.
EFIELD Universal WM051 Laundry Outlet Box
The WM051 offers a center drain configuration with a 1/2-inch MIP inlet and 3/4-inch MHT outlet. It includes stainless steel water hammer arrestors and a 1/4-turn hot and cold valve arrangement. The universal fit makes it a versatile choice for homes with sweat-to-MIP transitions or mixed piping layouts. This box is well-suited for renovations where standardized center-drain access and reliable surge control matter most.
EFIELD Premium WM029 Laundry Box with Center Drain
The WM029 model features a 1/2-inch sweat MIP inlet coupled to a 3/4-inch MHT outlet, with a center-drain layout. It ships with a 1/4-turn hot and cold valve pre-installed, simplifying installation for standard residential laundry areas. Sweat-to-MIP compatibility makes this box a practical pick when upgrading existing copper or copper-combined piping, reducing the need for extra adapters.
SUNGATOR Washing Machine Outlet Box
The SUNGATOR unit is compatible with crimp PEX systems, using a 1/2-inch PEX inlet and a 3/4-inch FHT outlet. It includes pre-installed brackets and clamps, plus a center and side drain design. The recessed profile helps with space-limited laundry closets. Two support brackets help bridge gaps between mounting plates, which can simplify mounting on uneven walls or stud layouts.
Oatey Quadtro/MODA Washing Machine Outlet Box
The Oatey Quadtro/MODA box is designed for compatibility with the Quadtro and MODA system families. It supports right, left, or center drains and offers flame-free, versatile valve mounting via its Lock and Load system. This makes it a strong candidate for multi-drain configurations and professional installers seeking flexible alignment and mounting options.
Buying Guide
- Compatibility: Confirm inlet and outlet sizes match your existing piping (1/2″, 3/4″, PEX, sweat, or MIP). Some models suit crimp PEX, while others work with sweat or threaded connections.
- Drain configuration: Center drains are common for modern washers, but side drains may fit tighter spaces. Consider space layout and future accessibility for hose maintenance.
- Water hammer protection: Built-in stainless steel arrestors reduce water hammer and pipe noise. If your home has older piping, this feature can improve system longevity.
- Valve configuration: 1/4-turn ball valves offer precise control and longer service life. Pre-installed valves simplify installation, but verify compatibility with your water supply lines.
- Installation ease: Look for included brackets, clamps, or mounting systems. Recessed designs save space in tight laundry closets and utility rooms.
- Durability and material: Stainless steel arrestors and robust plastics/metal housings extend the life of the rough-in after repeated use and temperature changes.
- Future upgrades: If you anticipate changing plumbing materials, prefer universal or easily adaptable boxes that accommodate different inlet types (Pex, MIP, sweat).
- Code considerations: Ensure the chosen box complies with local plumbing codes and any builder requirements, especially in multi-unit buildings.
