Connecting Faucets with Supply Tubes


Connecting your faucet to hot and cold water supply tubes is an easy project.  Start by measuring the distance between your faucet and the shut-off valves.  Add 4” to allow for any twists and turns then purchase the correct length of braided steel or vinyl mesh faucet supply tubing to connect your faucet to the hot and cold shut-off valves. Be sure the supply lines you purchase have the right connection types for your shut-off valves. Read the Labeling section of our Flexible Supply Lines buying guide and watch our Plumbing Compression Fittings video to learn more about these connections. As you refer to the steps in this guide, be sure to follow any specific instructions that come with your faucet or supply connectors.
