Step 2 · Prepare Work Area & Disconnect Supply Line
Prepare your workspace under the sink. Clear out any cleaning supplies or other items to create ample room to maneuver. Place a bucket directly beneath the angle stop you are replacing to catch residual water. Have several old towels ready to absorb any spills. Using an adjustable wrench, grip the nut connecting the flexible faucet supply line to the top of the angle stop. Turn the nut counter-clockwise to loosen it. Once it's loose, you can typically unscrew it the rest of the way by hand and pull the supply line away from the valve.
