Step 2 · Disconnect Faucet Supply Line

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

The angle stop is connected to the faucet via a flexible water supply line. Using an adjustable wrench or channel-lock pliers, loosen the coupling nut that secures this supply line to the top or side of the angle stop. Turn the nut counter-clockwise ('lefty-loosey'). You may need to hold the valve body steady with your other hand to prevent it from twisting. Once loosened, you can typically unscrew it the rest of the way by hand. Move the supply line out of the way.
