Installation Instructions
Important: Ensure the main water supply is turned off before beginning installation. Keep the valve handles in the closed position during installation.
- Prepare the Wall Opening: Identify the desired location for the outlet box, typically between wall studs. Cut an opening in the drywall or wall material that accommodates the dimensions of the box. Ensure there is sufficient space for plumbing connections.
- Mount the Box: The outlet box is designed for recessed installation. Use the pre-installed support brackets to secure the box to the wall studs. The brackets can be adjusted to reach distant mounting plates if necessary. Ensure the box is level and securely fastened.
- Connect PEX Inlets: Connect your 1/2 inch PEX water supply lines to the Pex Crimp inlets on the valves. Use appropriate PEX crimp tools and rings to ensure a secure, leak-free connection. The valves are clearly marked for hot (red handle) and cold (blue handle) water.
- Connect Drain Line: Connect your washing machine drain hose to the center drain opening at the bottom of the box. Ensure a proper seal to prevent leaks.
- Install Washing Machine Hoses: Once the box is securely installed and water lines are connected, attach your washing machine's 3/4 inch MHT hoses to the outlets on the valves. Hand-tighten, then use a wrench for a quarter turn to ensure a snug fit without overtightening.
- Install Faceplate: Once all connections are made and tested, snap the protective box cover (faceplate) into place over the outlet box for a clean, finished appearance.
- Test for Leaks: Slowly turn on the main water supply. Inspect all connections for any signs of leaks. If leaks are detected, turn off the water supply and re-tighten or re-crimp connections as needed.

Operation
The Seelink Washing Machine Outlet Box features quarter-turn ball valves for easy operation. To turn on the water supply to your washing machine, rotate the red (hot) and blue (cold) handles 90 degrees until they are parallel with the water pipes. To turn off the water supply, rotate the handles 90 degrees until they are perpendicular to the water pipes. It is recommended to turn off the water supply to the washing machine when it is not in use for extended periods, such as during vacations, to prevent potential leaks or water damage.
Maintenance
The Seelink Washing Machine Outlet Box requires minimal maintenance. Periodically inspect the connections for any signs of leaks, corrosion, or wear. Ensure the valve handles turn smoothly. If you notice any issues, turn off the main water supply and address them promptly. The lead-free brass construction is designed to resist rust and corrosion, ensuring long-term durability.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose connections at PEX inlets or MHT outlets. Damaged PEX crimp. | Turn off water supply. Check and tighten all connections. Re-crimp PEX connections if necessary. Ensure washing machine hoses have good washers. |
| Water Hammer Noise | Sudden stopping of water flow. | This model includes integrated water hammer arrestors designed to mitigate this issue. If noise persists, consult a plumbing professional. |
| Valves Difficult to Turn | Mineral buildup or internal wear. | The quarter-turn ball valves are designed for smooth operation. If a valve becomes stiff, it may indicate internal issues. Replacement of the valve or unit may be required. |
