Begin by locating the hot and cold water shut-off valves, which are typically found on the wall or floor beneath the sink. Grasp the handle of each valve and turn it clockwise until it stops. This action will cut off the water flow to the faucet. To confirm the water is off and to relieve any pressure in the lines, turn on the faucet handles above the sink.

FAQs

What should I do if I can't find or turn the water shut-off valves under my sink?

If the shut-off valves are stuck or inaccessible, try applying penetrating oil and letting it sit. If they still won't budge, you'll need to turn off the main water supply to your house, usually located in your basement, garage, or outside. This is a crucial step to prevent flooding.

Are the two adjustable wrenches listed sufficient, or are there other tools that would make this job easier for a beginner?

While adjustable wrenches are essential, a basin wrench can be incredibly helpful for reaching and loosening stubborn nuts in tight spaces under the sink. A utility knife or scraper can also assist in cleaning the old sealant effectively. Always have a bucket and towels handy for drips.

How thoroughly do I need to clean the sink surface before installing the new faucet?

It's crucial to clean the sink surface thoroughly to remove all traces of old plumber's putty, silicone, and grime. Use a cleaning paste like 'THE PINK STUFF' and a sturdy sponge to ensure the surface is perfectly clean and dry. A clean surface ensures a proper, watertight seal for your new faucet.

What's the most common reason for leaks after installing a new faucet, and how can I prevent them?

The most common reasons for leaks are improperly tightened supply lines or mounting nuts, or an inadequate seal at the faucet base. Ensure all connections are hand-tightened first, then snugged with a wrench without overtightening. Always check manufacturer instructions for any specific sealants or gaskets required.
