3. Setup & Installation
3.1 Package Contents
Verify that all components are present before beginning installation:
- Exposed shower system body
- S-2252 Brass Shower Head
- Cross handles (2)
- Mounting hardware
3.2 Pre-Installation
- Shut off the main water supply to the installation area.
- Clear the installation area of any debris or obstructions.
- Ensure that the wall surface is clean and prepared for mounting.
- Gather necessary tools, which typically include a pipe wrench, adjustable wrench, screwdriver, measuring tape, and thread sealant (Teflon tape or pipe dope).
3.3 Installation Steps
- Mount the Shower Body: Position the exposed shower system body on the wall at the desired height. Mark the mounting points. Drill pilot holes if necessary and secure the shower body to the wall using the provided mounting hardware.
- Connect Water Lines: Connect the hot and cold water supply lines to the corresponding inlets on the shower body. Apply thread sealant to all threaded connections to ensure a watertight seal. The system can be plumbed from above or below; if plumbing from below, the mixer body can be inverted, and the hot/cold index buttons can be switched.
- Install Cross Handles: Attach the cross handles to the valve stems. Ensure they are securely fastened and operate smoothly.
- Attach Shower Head: Screw the S-2252 Brass Shower Head onto the shower arm. Hand-tighten, then use a wrench for a final quarter turn, being careful not to overtighten. Apply thread sealant to the shower arm threads.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. Tighten any leaking connections as needed.

Figure 3: Allowed showerhead flow rate by state (GPM - Gallons Per Minute).
4. Operating Instructions
The Speakman SC-1220-AF Commander Exposed Shower System features two cross handles for precise control of water temperature and flow.
- Turning On/Off: Rotate the handles clockwise to turn off the water and counter-clockwise to turn on the water. The ¼ turn ceramic cartridges provide smooth operation.
- Adjusting Temperature: The left handle typically controls hot water, and the right handle controls cold water. Adjust both handles simultaneously to achieve the desired water temperature.
- Adjusting Flow: The flow rate is controlled by how much each handle is opened. Open both handles fully for maximum flow.
5. Maintenance
Regular cleaning and proper care will ensure the longevity and appearance of your Speakman shower system.
- Cleaning the Finish: Clean the polished chrome finish with a soft, damp cloth and mild soap. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots. Avoid abrasive cleaners, scouring pads, or chemicals containing ammonia, bleach, or alcohol, as these can damage the finish.
- Shower Head Cleaning: Periodically clean the shower head nozzles to remove mineral deposits. Many shower heads feature rubber nozzles that can be wiped clean with a finger or soft brush. For stubborn deposits, a solution of white vinegar and water can be used.
- Corrosion Resistance: The low-lead brass construction and corrosion-resistant finish are designed for durability. However, proper cleaning practices are essential to maintain this resistance.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged shower head nozzles; partially closed shut-off valves; mineral buildup in pipes. | Clean shower head nozzles. Ensure water supply valves are fully open. Consult a plumber if mineral buildup is suspected in the plumbing. |
| Leaks at Connections | Loose connections; insufficient thread sealant. | Ensure all connections are tightened properly. If necessary, disassemble, reapply thread sealant (Teflon tape or pipe dope), and reassemble. |
| Water Temperature Issues | Improper adjustment of hot/cold handles; issues with water heater. | Adjust hot and cold handles to achieve desired temperature. Check water heater settings if hot water is consistently too cold or too hot. |
