How to Install a Washing Machine Outlet Box · Step 6 of 7
This guide provides verbose instructions for installing a recessed washing machine outlet box in an existing wall. The process involves cutting into drywall, mounting the box between studs, running new PEX water supply lines, and connecting a new PVC drain line to the home's main Drain-Waste-Vent (DWV) system.

FAQs
Is a powerful tool like the Milwaukee SAWZALL absolutely necessary for cutting into the wall and studs, or are there suitable alternatives for a DIYer who doesn't own one?
While a SAWZALL makes quick work of studs and drywall, it's not strictly mandatory. For drywall, a jab saw or oscillating multi-tool can be used. For wood studs, an oscillating multi-tool with a wood blade or a manual handsaw will work, though it will be more time-consuming and labor-intensive.
What crucial safety precautions should I take before starting this project, especially when dealing with existing plumbing and cutting into walls?
Always shut off the main water supply to your home before cutting any existing water lines to prevent flooding. Wear appropriate personal protective equipment (PPE) such as safety glasses and durable gloves (like the Nitrile Gloves mentioned). Use a reliable stud finder to check for electrical wiring in the wall cavity before making any cuts to avoid serious hazards.
The project is rated 'intermediate' and 8 hours. What aspects typically make this project challenging for a DIYer, and what can extend the installation time?
The main challenges often involve accurately locating and cutting into existing DWV lines without causing leaks, and properly securing the new outlet box within the wall cavity. Unforeseen issues like discovering unexpected electrical wires, dealing with old or difficult-to-cut studs, or struggling with PVC solvent welding can significantly extend the estimated 8-hour timeframe.
What are the most common mistakes DIYers make when connecting the new PVC drain line to the home's main DWV system, and how can I ensure a leak-free connection?
Common mistakes include insufficient primer or cement application, incorrect pipe alignment, or not allowing adequate cure time for the cement. To ensure a leak-free connection, thoroughly clean and prime both pipe ends, apply a generous but even coat of 1 Step PVC Cement, and twist the pieces firmly together for a secure bond. Always follow the cement manufacturer's cure time recommendations before testing.
