Step 2 · Disconnect Faucet Supply Line
With a bucket in place, the next step is to disconnect the faucet supply line from the angle stop. This is the flexible or rigid tube that runs from the valve to the faucet's threaded tailpiece. Using an adjustable wrench, grip the nut connecting the supply line to the top outlet of the angle stop. Turn the nut counter-clockwise to loosen it. Be prepared for a small amount of water to drip out. Once fully loosened, pull the supply line away from the valve.
