How do you connect supply lines to a kitchen faucet?

  1. TURN OFF THE WATER. Turn off the water at the shutoff valves under the sink or at the main water supply.
  2. ATTACH THE SUPPLY CONNECTORS TO THE FAUCET. If your faucet comes with supply connectors already attached to the faucet, skip this step and proceed to Step 3.

Then, what size supply line is needed for a kitchen faucet?

It seems the all the supply pipes (bathroom sink, kitchen sink, toilet) from the wall are 1/2" pipes. Looking at homedepot's site, the most common valve is 1/2" to 3/8". And the most common faucet supply line is the opposite 3/8" to 1/2".

Secondly, do faucets come with supply lines? Many new faucets include supply lines, but they may not be long enough, or they may not have the right threads to connect to your shutoff valves. To determine the length of the supply lines you'll need, measure from the underside of the sink near where the faucet connects to the shutoff valve and add a few inches.

Also to know is, how do you connect a hose to a kitchen faucet?


  1. Get a faucet adapter. This is a small adapter that screws onto the faucet and converts the end of the faucet into a male garden hose fitting.
  2. Unscrew the faucet tip.
  3. Screw on the new faucet adapter.
  4. Make sure the hose gasket is in place the hose has a rubber or vinyl gasket in it to prevents leaks.
  5. Screw on the hose.

Do I need Teflon tape on faucet supply lines?

Most faucets will have hot and cold water supply lines attached, so you just need to connect them to the appropriate water supply line. You may need to use Teflon tape (aka plumber's tape) for this part, which is used to seal and lubricate threaded pipe joints.
