Prevent leaks and save money with new supply tubes for your sink
Connecting your faucet to the hot and cold supply lines begins with measuring the distance between the faucet and shutoff valves, then adding 4 inches for any twists and turns.
Be sure the supply lines you purchase have the right connection types for your shutoff valves.
This guide will teach you the correct way to connect your new supply lines to your faucet’s hot and cold shutoff valves.
WHAT YOU NEED FOR THIS PROJECT
Turn off the water at the shutoff valves under the sink or at the main water supply.
If your faucet comes with supply connectors already attached to the faucet, skip this step and proceed to Step 3.
If you have no connectors, follow these steps:
• Wrap Teflon tape or thread sealant around the threads on the faucet’s male hot and cold fittings.
• Attach the supply connectors to the faucet body.
• Label the hot and cold supply connectors so you can attach them to the appropriate tubes when you’re under the sink.
• Insert the threaded tailpiece(s) and supply connectors into the pre-drilled holes in the sink or countertop.
• Secure the faucet to the sink by placing a rubber gasket, retainer ring and nut onto the threaded tailpiece.
• Next, tighten the nut with your fingers then give it a quarter-turn with a basin wrench or a pair of water-pump pliers.
• Be careful not to crack the countertop by over tightening the nut.
Wrap all male threads with Teflon tape or apply some form of thread sealant. Next, use two adjustable wrenches to connect the hot (red-coded) and cold (blue-coded) supply lines to the shutoff valves.
Turn on the water and check for any leaks around all of the new connections. Lastly, check and tighten connections where any leaks occur.
