4. Setup & Installation
This trim is designed for installation with Newport Brass 1-606 and 1-607 Stop Valves and 1-617 Diverter Valve (sold separately). Refer to the specific valve's instruction manual for rough-in details.
4.1. Preparation
- Ensure the main water supply is turned off.
- Confirm that the Newport Brass rough-in valve (1-606, 1-607, or 1-617) is properly installed and secured within the wall.
- Clean the area around the valve to ensure a clear and smooth surface for the trim.
4.2. Trim Installation
- Position the escutcheon (if included) over the valve body, ensuring it sits flush against the finished wall.
- Align the diverter/flow control trim assembly with the valve stem.
- Secure the trim assembly to the valve body using the provided mounting screw(s). Hand-tighten initially, then use a screwdriver to gently snug the screws. Do not overtighten.
- Attach the metal cross handle to the stem, ensuring it is properly seated. Secure with the set screw (if applicable) using an Allen wrench.
- Once installation is complete, slowly turn on the main water supply and check for any leaks.
5. Operating Instructions
The Newport Brass NB3-163B-10 trim functions as a diverter or flow control, depending on the valve it is paired with.
5.1. Diverter Function (with 1-617 Diverter Valve)
- Rotate the cross handle to divert water flow between different outlets (e.g., showerhead to hand shower, or tub spout to showerhead).
- The handle typically has distinct stop positions for each outlet.
5.2. Flow Control Function (with 1-606 or 1-607 Stop Valves)
- Rotate the cross handle to turn the water flow on or off, and to adjust the volume of water.
- Turning the handle clockwise typically reduces flow or turns it off. Turning counter-clockwise increases flow or turns it on.
6. Maintenance
Proper care and maintenance will ensure the lasting beauty and performance of your Newport Brass product.
- Cleaning: Clean the trim regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishes that contain alcohol, ammonia, or bleach, as these can damage the finish.
- Finish Care: For Satin Bronze (PVD) finishes, a mild soap and water solution is generally sufficient. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Periodic Inspection: Periodically check for any signs of wear or loose components. Tighten screws gently if necessary.
7. Troubleshooting
If you encounter issues with your diverter/flow control trim, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Trim is loose or wobbly. | Mounting screws are loose. | Gently tighten the mounting screw(s) behind the handle or escutcheon. Do not overtighten. |
| Handle is difficult to turn. | Mineral buildup or internal valve issue. | Clean the exterior of the handle and trim. If the issue persists, the problem may be with the rough-in valve, not the trim. Consult a plumber. |
| Water leaks from behind the trim. | Improperly sealed valve or damaged O-rings/gaskets within the rough-in valve. | Turn off water supply immediately. This usually indicates an issue with the rough-in valve installation or internal components, not the trim itself. Consult a qualified plumber. |
