How to Install a Single Handle Kitchen Faucet with Sprayer

Step 1: Turn Off the Water Supply

Your safety is paramount, so before you commence any work, ensure the water supply to your kitchen is turned off. Locate the shut-off valves beneath the sink and rotate them clockwise until they’re fully closed. To eliminate any remaining water from the pipes, turn on the faucet.

Step 2: Disconnect the Old Faucet

Detach the supply lines and remove the old faucet using an adjustable wrench and a pipe wrench. Place a bucket or towels beneath the work area to collect any water that may drip during this process. If your previous faucet had a sprayer hose, remember to disconnect that as well.

Step 3: Clean the Sink Area

With the old faucet removed, take the opportunity to thoroughly clean the sink area. Removing any accumulated debris, old sealant, and residue will ensure a clean and stable surface for the new faucet.

Step 4: Apply Plumber’s Tape

Before installing the new faucet, wrap a few layers of plumber’s tape (Teflon tape) around the threads of the water supply connectors. This tape will help create a secure and leak-free seal when you attach the supply lines.

Step 5: Install the New Faucet

Insert the new faucet’s supply lines through the mounting hole in the sink. From beneath the sink, align the faucet with the mounting hole and secure it in place using the provided mounting nuts. Utilize an adjustable wrench to tighten the nuts, but avoid over-tightening, as it could cause damage.

Step 6: Attach the Sprayer Hose

If your new single handle kitchen faucet comes with a sprayer, attach the sprayer hose to the designated outlet on the faucet. Use an adjustable wrench to ensure a firm and leak-free connection.

Step 7: Connect the Supply Lines

Connect the hot and cold water supply lines to their respective connectors on the faucet. Again, use an adjustable wrench to tighten the connections, exercising caution not to over-tighten.

Step 8: Check for Leaks

Before proceeding further, perform a leak check. Gradually turn on the water supply valves beneath the sink and meticulously inspect all connections for any signs of leakage. Should you detect any leaks, promptly tighten the connections as necessary.

Step 9: Seal the Base

To prevent water from seeping underneath the faucet, apply a thin, uniform bead of silicone sealant around the base where it meets the sink. This sealant will serve as a protective barrier and maintain the integrity of the installation.

Step 10: Test the Faucet and Sprayer

With iinstalling kitchen faucet almost complete, turn on the faucet and the sprayer to verify the water flow and functionality. Test both hot and cold water settings to ensure they work smoothly without any leaks or issues.
