Safety Information
Always turn off the main water supply before beginning any plumbing work. Wear appropriate personal protective equipment, such as safety glasses and gloves. If you are unsure about any step, consult a qualified plumber. Do not overtighten connections, as this can damage the hose or fittings.
Package Contents
Verify that all components are present before beginning installation. The package should contain:
- RKF 23.6 Inch Faucet Supply Line (Model H02) - 1 or 2 units (depending on purchase)
Setup (Installation)
- Preparation: Turn off the main water supply to the area where the faucet is located. Clear the workspace under the sink. Ensure you have the necessary tools (adjustable wrench, plumber's tape if desired).
- Connect to Faucet: Connect one end of the supply line to the threaded shank of your faucet. Hand-tighten the connection first, then use an adjustable wrench to tighten an additional quarter to half turn. Do not overtighten.
- Connect to Water Supply Valve: Connect the other end of the supply line to the corresponding hot or cold water supply valve. Hand-tighten, then use an adjustable wrench for a quarter to half turn.
- Leak Check: Slowly turn on the main water supply. Carefully inspect all connections for any signs of leaks. If a leak is detected, turn off the water, tighten the connection slightly, and recheck.

Operating (Usage)
Once properly installed and checked for leaks, the RKF Faucet Supply Line operates automatically to deliver water from your supply valves to your faucet. No further user interaction is required for its basic function. Ensure that the water supply valves are fully open for optimal water flow.
Maintenance
Regular inspection and minimal maintenance will ensure the longevity of your supply line:
- Periodic Inspection: Annually, or if you notice any changes in water pressure or signs of moisture, inspect the entire length of the supply line and all connections for signs of wear, corrosion, kinks, or leaks.
- Cleaning: Clean the exterior of the supply line with a soft cloth and mild, non-abrasive soap if needed. Rinse thoroughly with water and dry. Avoid using harsh chemicals or abrasive cleaners, as these can damage the stainless steel braiding.
- Tightening Connections: If minor seepage is observed, gently tighten the connections with an adjustable wrench. Do not overtighten.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leakage at connections | Loose connection, damaged washer, or cross-threaded fitting. | Turn off water supply. Gently tighten the connection. If leakage persists, disassemble, inspect the washer for damage, replace if necessary, and reassemble carefully. Ensure threads are aligned correctly. |
| Low water flow | Kinked supply line, partially closed water supply valve, or debris in the line. | Check the supply line for any kinks and straighten them. Ensure the water supply valve is fully open. If flow is still low, turn off water, disconnect the line, and check for any obstructions. |
