How to Install Kitchen Sink Supply Lines on to Faucet Valves

Replacing the supply lines to your kitchen sink can save you the cost of a plumber's repair bill and prevent damage incurred by leaking lines before the plumber arrives. With a little patience, most homeowners can manage this job in a short time and learn something about plumbing in the process.

Instructions

1. Turn off the water supply. You'll find a shut-off valve under your kitchen sink. Once the water is turned off, open up the kitchen faucets to allow the water remaining in the pipes to drain way.

2. Catch the drips by placing a bucket under the hot water supply line, located on the left side of your sink. Even a minimum of water can cause a mess and be potentially damaging.

3. Use a wrench to remove the compression nut that secures the hot water supply line. Let the disconnected section fall into the bucket. Use the wrench to loosen and remove the nut at the other end of the line and remove it as well.

4. Repeat Steps 2 and 3 for the cold water supply line.

5. Replace the cold water supply line. Hand-tighten the nuts on both ends, then use the wrench to tighten the nuts completely. Repeat the process with the hot water supply line.

6. Turn on the water supply and test for leaks.
