Safety First: Shutting Off the Water Supply

The most important step before starting any plumbing work is to shut off the water supply to your kitchen faucet. Here’s how:

1. Locate the Shut-Off Valves: These are typically located under the sink, one for hot water and one for cold water.
2. Turn Off the Valves: Turn both valves clockwise until they are completely closed.
3. Test the Water: Turn on the old faucet briefly to ensure the water is completely shut off. If water continues to flow, locate the main water shut-off valve for your home and turn it off.

2. Loosen the Mounting Nuts: Use a basin wrench to loosen the nuts that secure the old faucet to the sink. These nuts are usually located in a hard-to-reach area under the sink. Penetrating oil can be helpful if the nuts are corroded or stuck.
3. Remove the Old Faucet: Once the nuts are loosened, carefully remove the old faucet from the sink.
4. Clean the Sink Surface: Thoroughly clean the sink surface around the faucet hole to remove any old putty, sealant, or debris. A scraper and some cleaning solution can be helpful.
