3. Product Overview
The Sioux Chief 696-2313MF Oxbox consists of two separate boxes designed for a washing machine installation. One box houses the hot and cold water supply valves with integrated water hammer arresters, while the other is for the washing machine drain hose. This design allows for flexible placement within two adjacent stud bays.

Figure 1: Sioux Chief 696-2313MF Oxbox Washing Machine Outlet Box. This image displays the two-part outlet box, with one section containing the water supply valves and water hammer arresters, and the other section designed for drainage. The image also indicates product dimensions, showing a height of 9.2 inches (23 cm).
The water hammer arresters are crucial components that absorb pressure surges in the water lines, preventing the banging noises often associated with washing machine valves closing rapidly. The 1/2 CP x MIP connections ensure compatibility with standard plumbing fittings.
4. Setup & Installation
Proper installation is critical for the safe and efficient operation of your Oxbox. Follow these steps carefully:
- Prepare the Installation Area:
- Ensure the main water supply to the house is turned off.
- Locate the desired position for the outlet box, typically between wall studs in the laundry area. The separate boxes allow for installation in adjacent stud bays if needed.
- Remove any existing plumbing or wall coverings as necessary.
- Mount the Boxes:
- The Oxbox units are designed to mount securely to a stud or over studs. Position the boxes at the appropriate height for your washing machine connections.
- Use screws or nails (not included) to firmly attach the boxes to the framing. Ensure they are level and plumb.
- The debris covers should remain in place during drywall installation and painting to protect the internal components.
- Connect Water Supply Lines:
- Connect the hot and cold water supply lines from your home plumbing system to the 1/2 CP x MIP inlets on the back of the valve box.
- Use appropriate plumbing techniques (e.g., soldering, PEX crimping, or threaded connections with sealant) to ensure watertight and secure connections.
- The integrated Minister Water Hammer Arresters are pre-installed on the valves.
- Connect Drain Line:
- Connect the washing machine drain line to the drain opening in the second Oxbox unit. This typically involves a standard PVC or ABS drain pipe connection.
- Ensure a proper seal to prevent leaks.
- Final Checks:
- Once all connections are made and the wall is finished (if applicable), remove the debris covers.
- Slowly turn on the main water supply.
- Inspect all connections for leaks. Tighten any leaking connections immediately.
- Connect your washing machine's hot and cold supply hoses to the valves and the drain hose to the drain opening.
5. Operation
Operating the Sioux Chief Oxbox is straightforward once installed:
- Water Supply: The two levers on the valve box control the hot and cold water supply to your washing machine. Turn the levers to the "ON" position (typically aligned with the pipe) to allow water flow. Turn them to the "OFF" position (perpendicular to the pipe) to shut off the water.
- Water Hammer Arresters: The integrated arresters automatically absorb pressure shocks from the washing machine's solenoid valves, reducing pipe noise and protecting your plumbing system. No user intervention is required for their operation.
- Drainage: The open drain box provides a secure and accessible point for your washing machine's drain hose. Ensure the drain hose is properly seated to prevent splashing or overflow.
It is recommended to turn off the water supply to the washing machine using the Oxbox valves when the machine is not in use for extended periods, such as during vacations, to prevent potential leaks or hose bursts.
6. Maintenance
The Sioux Chief Oxbox is designed for minimal maintenance. However, periodic checks can help ensure its longevity and proper function:
- Leak Inspection: Periodically check all connections for any signs of leaks. Address any leaks promptly by tightening connections or replacing seals if necessary.
- Valve Operation: Occasionally operate the hot and cold water valves by turning them fully on and off to ensure they move freely and seal properly.
- Cleaning: The exterior of the box can be wiped clean with a damp cloth. Avoid using harsh abrasive cleaners that could damage the ABS material.
- Debris Covers: If the debris covers were removed after installation, store them in a safe place. They can be re-used if future wall work is performed.
7. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose connections, damaged seals/gaskets, cracked pipe. |
|
| Water Hammer Noise (Banging Pipes) | Rapid closing of washing machine valves, insufficient water hammer arresters (unlikely with integrated ones), air in pipes. |
|
| No Water Flow to Washing Machine | Valves are closed, main water supply is off, clogged supply line. |
