4. Operating Instructions
Once the MultiChoice Universal Valve Body is installed and your chosen Delta trim kit is in place, operation is straightforward. The specific functions (single-function, dual-function, or thermostatic) will depend on the trim kit selected.
- Temperature Control: Adjust the handle to achieve your desired water temperature. Pressure-balanced and thermostatic cartridges maintain consistent temperature.
- Volume Control: For dual-function and thermostatic trim kits, a separate handle or function allows for independent control of water volume.
- Diverter Function: If your trim kit includes a diverter, use it to switch water flow between the showerhead and tub spout.
5. Maintenance
The Delta MultiChoice Universal Valve Body is constructed from durable brass, designed for long-lasting performance. Regular maintenance of your visible trim kit will help ensure optimal function and appearance.

- Cleaning: For the visible trim, use a soft, damp cloth and mild soap. Avoid abrasive cleaners, steel wool, or harsh chemicals that can damage the finish.
- Cartridge Replacement: If you experience issues with water flow or temperature control, the cartridge may need replacement. Refer to your specific trim kit's manual for instructions or consult a professional plumber.
6. Troubleshooting
Most operational issues related to your tub and shower system are typically associated with the trim kit or cartridge rather than the valve body itself. If you encounter problems, consider the following general steps:
- No Water Flow or Low Pressure: Check your main water supply. Ensure the valve's internal stops (if present on your specific model) are fully open.
- Inconsistent Temperature: This often indicates an issue with the pressure-balancing or thermostatic cartridge. The cartridge may need cleaning or replacement.
- Leaks: Inspect connections for tightness. Leaks from the trim usually indicate a worn cartridge or O-rings.
- Consult a Professional: For complex issues or if you are unsure about any step, it is highly recommended to contact a licensed plumber.
