Washing Machine Outlet Box 1/2 in CPVC x 3/4 in MHT - Recessed Valve

Our review of this washing machine outlet box finds it best suited for homeowners and installers who need a reliable recessed valve box with straightforward plumbing connections. The biggest reason to buy is its combination of a raised drip guard and pre-installed copper water hammer arrestor that reduce leak risk and water shock without extra parts. Installation is aimed at recessed setups and supports both traditional and inverted mounting, so it fits a range of laundry room layouts while using standard 1/2 in CPVC inlet and 3/4 in MHT outlet fittings.

Key Features

• Robust construction: Made from high-impact, non-corrosive UPC certified materials and lead-free brass to resist rust and temperature extremes for long life.
• Versatile drain options: Designed for both central and side drains so it adapts to different plumbing layouts without modification.
• Leak protection: The raised drip guard helps contain incidental drips and reduces the chance of water damage behind the wall.
• Effortless setup: Recessed installation with support brackets and compatibility with inverted or standard mounting makes it quick to mount and align.
• Standard pipe compatibility: Comes with a 1/2 in CPVC inlet and a 3/4 in male hose thread outlet to match common washer supply lines.
• Included copper arrestor: The preinstalled copper water hammer arrestor reduces pressure spikes and protects valves and fittings.

Who It's For

This outlet box is a solid choice for DIY homeowners replacing or upgrading a washer connection and for professional plumbers installing a recessed valve box in a new or remodeled laundry area. The included copper arrestor and raised drip guard make it especially useful where minimizing water damage risk is a priority.

Those who should look elsewhere are shoppers needing unusual or nonstandard thread types, or anyone who requires a completely plastic unit without any metal components; a few customers reported mixed experience with thread quality, so buyers seeking premium machined fittings may prefer a higher-end model.
