The Oatey Quadtro and MODA washing machine outlet boxes are designed to provide convenient and accessible connections for washing machine water supplies and drain lines. Installation involves securing the box to wall studs, connecting drainpipes and water lines, and performing leak tests. Proper installation height is typically between 36 and 42 inches from the finished floor to the bottom of the box. The documentation emphasizes the importance of using approved Oatey primer and cement for secure connections and adhering to local building codes for pressure testing procedures.
Determining Location and Height
The initial step in installing an Oatey washing machine outlet box involves selecting an appropriate location. The documentation recommends ensuring the box is easily accessible and close to the washing machine fixture. It is also advised to consult the washing machine manufacturer’s recommendations regarding the optimal supply box location.
Once a location is chosen, the height must be determined and marked on the wall stud. A typical installation height ranges from 36 to 42 inches from the finished floor to the bottom of the box. Precise measurement and marking are crucial for ensuring the box is positioned correctly.
Preparing the Supply Box
Preparation steps vary slightly depending on the specific Oatey box model. For fire-rated MODA boxes, a large metal bracket should be slid onto the side of the box that will be attached to the stud. Additionally, an L-bracket is inserted through slots at the top of the box, positioned at a right angle facing upwards. These brackets contribute to the stability and secure mounting of the box.
Securing the Box to Wall Studs
After preparing the supply box, it must be securely attached to the wall studs. Nailing brackets are installed on the box and aligned with the measurements marked on the studs. The documentation does not specify the type or size of nails required, but emphasizes the importance of ensuring a firm and stable attachment.
Connecting the Drainpipe
Connecting the drainpipe is a critical step in the installation process, but is skipped for gas or valve-only MODA boxes. For standard and fire-rated MODA boxes, Oatey Purple Primer is first applied to both the drainpipe and the box hub. Following the primer application, Oatey Heavy Duty Clear PVC Cement is used to create a secure bond between the drainpipe and the box hub. This solvent cement process ensures a watertight seal.
Solvent Welding the P-Trap
Following the connection of the drainpipe, the P-Trap must be solvent welded to the drainpipe. Again, this step is skipped for gas or valve-only MODA boxes. The documentation stresses the importance of ensuring a tight seal during this process. Proper solvent welding prevents leaks and maintains the integrity of the drainage system.
Connecting Water Lines and Checking for Leaks
Once the drainpipe and P-Trap are connected, the water lines are secured into the valve bodies. After securing the water lines, the water supply should be turned on to check for any leaks. This initial leak check is a crucial step in verifying the integrity of the connections.
Pressure Testing and Final Leak Checks
The documentation recommends pressure testing the DWV (Drain-Waste-Vent) system or branch line to further verify the absence of leaks in the drain-to-box connection. If pressure testing is not feasible, it is advised to consult local building officials for an approved testing procedure. This testing should be completed before drywall installation.
After completing the pressure test or alternative testing procedure, the supply line hoses are connected to the valves, and the drain hose is inserted into the drain opening of the box. Finally, the appliance is cycled while carefully checking for any leaks in all connections.
Ensuring Stability and Tightness
Throughout the installation process, it is important to ensure the stability and tightness of all components. The documentation specifically advises thoroughly checking the tightness of all screws and confirming there is no looseness in any part of the supply box. This proactive approach helps prevent future issues and ensures a reliable installation.
Important Considerations
The documentation notes that the information provided is based on data believed to be reliable, but Oatey makes no warranties as to its accuracy and assumes no liability arising out of its use. Users should always consult local building codes and regulations to ensure compliance with all applicable requirements. Additionally, the documentation emphasizes the importance of using approved Oatey primer and cement for optimal results.
Conclusion
Installing an Oatey Quadtro or MODA washing machine outlet box requires careful attention to detail and adherence to the manufacturer’s instructions. Proper location selection, accurate measurement, secure connections, and thorough leak testing are all essential for a successful installation. By following the steps outlined in the provided documentation and consulting local building codes, users can ensure a reliable and long-lasting washing machine connection.
