Step 3 · Disconnect Water Supply Lines

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

With the bucket positioned underneath, use a basin wrench or an adjustable wrench to disconnect the hot and cold water supply lines from the faucet's valve bodies. The connection nuts turn counter-clockwise to loosen. If the nuts are corroded or stuck, apply a small amount of penetrating oil and wait 10-15 minutes before trying again. It's crucial to use a second wrench or pliers to hold the faucet valve body steady to prevent it from twisting and damaging the pipe.
