3. Setup and Installation
Installation of plumbing components should ideally be performed by a qualified professional to ensure compliance with local plumbing codes and proper functionality. Incorrect installation can lead to leaks or damage.
Required Tools and Materials (Not Included):
- Adjustable wrench or pipe wrench
- Thread seal tape (PTFE tape)
- Bucket or towels for water containment
Installation Steps:
- Turn off Water Supply: Locate the main water shut-off valve for your property or the specific fixture and turn it off completely. Open a nearby faucet to relieve pressure in the lines.
- Prepare Connection Points: Ensure the existing pipe threads are clean and free of debris. Apply thread seal tape clockwise around the male threads of the pipe where the valve will be connected.
- Connect the Valve: Carefully thread the Schell Comfort Secondary Connection Valve onto the prepared pipe. Hand-tighten first, then use an adjustable wrench to tighten an additional 1/4 to 1/2 turn. Avoid over-tightening, which can damage threads or the valve.
- Connect Hose/Fixture: Attach the desired hose or fixture connection to the valve's outlet. Ensure a watertight seal, using thread seal tape if necessary for threaded connections.
- Check for Leaks: Slowly turn the main water supply back on. Carefully inspect all connections for any signs of leaks. If leaks are detected, turn off the water supply, tighten the connection slightly, and re-check.
Note: The integrated backflow preventer ensures water flows in one direction only, preventing contamination of the main water supply. Ensure the valve is oriented correctly according to water flow direction indicators, if present.
4. Operating Instructions
The Schell Comfort Secondary Connection Valve is designed for simple operation to control water flow to a connected fixture.
- To Open the Valve (Allow Water Flow): Turn the control knob counter-clockwise until the desired water flow is achieved. For full flow, turn until it stops.
- To Close the Valve (Stop Water Flow): Turn the control knob clockwise until it stops. This will shut off the water supply to the connected fixture.
Caution: Do not force the control knob beyond its natural stopping points, as this may cause damage to the internal mechanism.
5. Maintenance
Regular maintenance helps ensure the longevity and proper function of your valve.
- Cleaning: Clean the chrome-plated surface with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads, which can damage the finish.
- Leak Checks: Periodically inspect all connections for any signs of leaks. Address any leaks promptly to prevent water damage.
- Operation Check: Occasionally operate the valve (open and close it) to ensure the mechanism moves freely and to prevent mineral buildup.
- Winterization (if applicable): In areas subject to freezing temperatures, ensure the valve and connected pipes are properly drained or insulated to prevent freeze damage.
6. Troubleshooting
This section addresses common issues you might encounter with your secondary connection valve.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leak at connections | Loose connection, insufficient thread seal tape, damaged washer/gasket. | Turn off water supply. Tighten connections. Reapply thread seal tape. Inspect and replace washers/gaskets if damaged. |
| No water flow or reduced flow | Valve not fully open, main water supply off, blockage in pipe or valve. | Ensure valve is fully open. Check main water supply. If problem persists, professional inspection may be required to check for blockages. |
| Valve difficult to turn | Mineral buildup, internal component wear. | Regular operation can prevent buildup. If severe, the valve may need to be replaced. |
If you are unable to resolve an issue using the troubleshooting steps above, please contact a qualified plumber or the manufacturer's support.
