The American Standard Townsend Tub and Shower Trim Kit is designed for use with a compatible Flash Shower Rough-in Valve (sold separately).

The kit incorporates double ceramic pressure balance technology for consistent water temperature and anti-scald protection.
Setup and Installation
Important: Installation of this product requires a Flash Shower Rough-in Valve, which is sold separately. It is recommended that installation be performed by a qualified professional plumber to ensure proper function and compliance with local codes.
- Preparation: Ensure the main water supply to the installation area is turned off. Clear the work area and gather all necessary tools.
- Rough-in Valve Installation: Install the Flash Shower Rough-in Valve according to its specific instructions. This trim kit is designed to connect to this valve.
- Trim Plate Installation: Secure the trim plate over the rough-in valve, ensuring it is flush with the wall surface.
- Handle Assembly: Attach the handle to the valve stem, following the rough-in valve's instructions for proper orientation and securing.
- Showerhead Installation: Apply plumber's tape to the threads of the shower arm. Thread the shower arm into the wall fitting and tighten. Attach the showerhead to the shower arm and tighten securely.
- Tub Spout Installation: Install the tub spout according to the specific instructions provided with the rough-in valve or the spout itself. Ensure a watertight seal.
- Final Check: Turn on the main water supply and check for any leaks. Test the operation of the handle, showerhead, and tub spout.

Operating Instructions
The Townsend Tub and Shower Trim Kit features a single handle for controlling both water flow and temperature.
- Turning On/Off: Rotate the handle from the "OFF" position to initiate water flow.
- Temperature Control: Rotate the handle counter-clockwise for hotter water and clockwise for colder water. The integrated double ceramic pressure balance cartridge maintains a consistent output temperature, protecting against sudden temperature changes.
- Flow Control: The handle also controls the volume of water. Further rotation from the "OFF" position increases flow.
- Diverter (Tub Spout): To switch water flow from the tub spout to the showerhead, pull up the diverter knob located on the tub spout. Push it down to return flow to the tub spout.

Maintenance and Care
Proper care will help maintain the finish and performance of your American Standard trim kit.
- Cleaning the Finish: Clean the brushed gold finish with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Cartridge Care: The ceramic disc mixing valve and ceramic balancing spool are designed for long-lasting, drip-free performance and are resistant to mineral deposits. No special maintenance is typically required for the cartridge under normal operating conditions.
- Showerhead Nozzles: Periodically clean the rubber nozzles on the showerhead to remove any mineral buildup. This can usually be done by gently rubbing them with your fingers.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged showerhead nozzles or debris in the cartridge. | Clean showerhead nozzles. If problem persists, consult a plumber to inspect the cartridge. |
| Inconsistent Water Temperature | Issues with the pressure balance cartridge or water heater settings. | Ensure water heater is functioning correctly. If the issue is with the trim kit, the ceramic balancing spool may need inspection by a professional. |
| Leaking from Handle or Spout | Loose connections or a faulty cartridge. | Check all connections for tightness. If leaking persists, the ceramic disc mixing valve may require replacement. Contact a qualified plumber. |
