Workspace Preparation

Get your workspace ready before you touch any pipes. First, turn off the main water supply. You can usually find the shut-off valve under the sink or near the main water line. Twist it clockwise until it stops. Next, open the faucet to drain any water left in the pipes. Place a bucket or towel under the pipes to catch drips.

Clear out anything stored under the sink. You need space to move and work. Good lighting helps you see what you're doing. Now you're ready to remove the old bathroom sink valve and start the replacement.
