Shut Off Water Supply

What happens here

First, observe the leak around the faucet's base to confirm the problem area. Then, locate the hot and cold water supply lines under the sink. Turn the ball valve style angle stops to the 'off' position (usually perpendicular to the pipe) to shut off the water supply to the faucet. This is a crucial safety step to prevent flooding during the repair.

Goal: Isolate the faucet from the water supply.
