Remove A Faucet Supply Line

Remove the faucet supply line from underneath your sink if it needs replacing.

The faucet supply line runs from the water supply valve to the inlet on the under side of the faucet. These hoses are flexible so that they can be strung from wherever needed to the faucet. However, they can sometimes break or spring a leak. When that happens, remove the faucet supply line as soon as possible and replace it with a new one.


1. Place a towel or old rag on the floor underneath the supply line that you want to remove.

2. Turn off the water supply valve where the supply line is connected. The supply valve is usually connected to the floor or wall where it meets the hose. Rotate the handle on the end of the supply valve to the right and cut the water.

3. Open up the faucet above and allow any water inside to run out.

4. Loosen the coupling where it meets the supply valve by turning it counterclockwise with an adjustable wrench.

5. Follow the other end of the supply hose to the underside of the sink. Unscrew the coupling connecting the supply line to the underside of the faucet. Remove the faucet supply line from underneath the faucet.

Tips Warnings

If the end of the supply line underneath the faucet is in a hard-to-reach location, purchase or rent a tool called a basin wrench that will allow you to more easily reach the coupling.
