Setup and Installation
Before beginning installation, ensure you have the correct length of supply lines. Measure the distance from the stub out to the water inlet on the faucet and add a few inches for flexibility. For example, if the measured length is 9 inches, consider ordering 12-inch lines for easier installation.
Required Tools (Not Included):
- Adjustable Wrench or Pliers
- Bucket (for catching residual water)
- Towel or Rag
Installation Steps:
- Turn Off Water Supply: Locate the main water shut-off valve for your home or the specific shut-off valves for the faucet you are working on (usually under the sink). Turn them off completely.
- Drain Residual Water: Open the faucet to drain any remaining water from the lines. Place a bucket under the existing supply lines to catch any drips when disconnecting.
- Remove Old Supply Lines: Use an adjustable wrench to carefully loosen and remove the old supply lines from both the faucet and the water shut-off valves.
- Connect New Supply Lines to Faucet: Identify the hot (red marking) and cold (blue marking) lines. Connect the appropriate ends of the new ARCORA supply lines to the corresponding inlets on your faucet. Hand-tighten first, then use a wrench for a snug fit. Do not overtighten.
- Connect New Supply Lines to Water Valves: Connect the other ends of the supply lines to the hot and cold water shut-off valves. Ensure the sealing washers are properly seated within the brass nuts to prevent leaks. Hand-tighten, then use a wrench for a snug fit.
- Restore Water Supply: Slowly turn the water shut-off valves back on. Check for any leaks at all connection points. If leaks occur, gently tighten the connections further until the leak stops.
- Test Faucet: Open the faucet to ensure proper water flow and temperature control.

Maintenance
ARCORA Faucet Supply Lines are designed for durability and minimal maintenance. However, regular checks can extend their lifespan and prevent potential issues.
- Periodic Inspection: Annually inspect the supply lines for any signs of wear, cracks, kinks, or corrosion. Pay close attention to the connection points for any signs of leakage or mineral buildup.
- Cleaning: If necessary, gently wipe the exterior of the lines with a damp cloth to remove dust or grime. Avoid using harsh chemicals or abrasive cleaners, as these can damage the braided nylon.
- Avoid Stress: Ensure the lines are not bent at sharp angles or under excessive tension, which can lead to kinking or premature failure. The flexible design allows for gentle curves.
- Replacement: While designed for longevity, it is generally recommended to replace supply lines every 5-10 years, or sooner if any signs of damage or degradation are observed.
Troubleshooting
If you encounter issues with your ARCORA Faucet Supply Lines, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage at Connection Points | Loose connection, improperly seated washer, damaged washer. | Turn off water supply. Gently tighten the connection with a wrench. If the leak persists, check if the washer is properly seated or if it needs replacement. Ensure the connection is not cross-threaded. |
| No Water Flow or Low Pressure | Water supply turned off, kinked line, debris in line or faucet aerator. | Ensure water supply valves are fully open. Check the supply line for any kinks or sharp bends and straighten them. If the issue persists, the problem might be with the faucet itself or the main water supply. |
| Hose Appears Kinked or Damaged | Improper installation, excessive bending, external damage. | If the kink is minor, gently straighten the hose. If the hose is severely kinked, cracked, or otherwise damaged, it must be replaced immediately to prevent leaks. |
If these troubleshooting steps do not resolve the issue, it is recommended to contact a qualified plumber or ARCORA customer support for assistance.
