Safety Information
- Always turn off the main water supply before beginning any plumbing work.
- Wear appropriate personal protective equipment, such as gloves and eye protection.
- If you are unsure about any step, consult a qualified plumber.
- Do not overtighten connections, as this can damage threads or sealing components.
Package Contents
- 2 x ARCORA Faucet Supply Lines (12 Inch, 3/8" Comp x 1/2" Comp)
Installation Instructions
- Prepare the Area: Turn off the main water supply to the faucet. Open the faucet to drain any remaining water from the lines. Clear the workspace under the sink.
- Remove Old Supply Lines (if applicable): Use a wrench to carefully disconnect the old supply lines from both the faucet and the water supply valves. Be prepared for some residual water.
- Determine Correct Length: Measure the distance from the water supply stub out to the faucet's water inlet. It is recommended to add a couple of inches to this measurement to allow for flexibility. This product is 12 inches in length.
- Connect to Faucet: Hand-tighten the 1/2-inch brass nut end of the new ARCORA supply lines to the faucet's inlet shanks. Ensure the sealing washer is properly seated to prevent leaks. Use a wrench to tighten an additional 1/4 to 1/2 turn. Do not overtighten.
- Connect to Water Supply Valves: Hand-tighten the 3/8-inch female compression end of the supply lines to the water supply valves. Ensure the sealing washer is properly seated. Use a wrench to tighten an additional 1/4 to 1/2 turn. Do not overtighten.
- Check for Leaks: Slowly turn on the main water supply. Inspect all connections for any signs of leaks. If leaks are detected, gently tighten the connections until the leak stops. Do not overtighten.

Operation
Once installed, the ARCORA Faucet Supply Lines operate passively as part of your plumbing system. Ensure all connections remain tight and free of leaks for continuous, reliable water flow.
Maintenance
Periodically inspect the supply lines for any signs of wear, corrosion, or damage. While these lines are designed for longevity, it is good practice to check plumbing connections during routine home maintenance. Clean the exterior with a soft cloth and mild soap if necessary.
Troubleshooting
- Leakage at Connections: Ensure all connections are properly tightened. Verify that the sealing washers are correctly seated and not damaged. Do not overtighten, as this can damage the washers or threads.
- Low Water Pressure: If water pressure is low after installation, ensure the water supply valves are fully open. Check for any kinks in the supply lines, although the braided design minimizes this risk.
