Installing a new kitchen faucet can make your sink area look cleaner, more modern, and easier to use. While many homeowners like doing it themselves, it can sometimes be tricky if you’re not used to plumbing work. In such cases, our professional services at Order a Plumber can make the job quick, neat, and stress-free. Here’s a detailed, simple guide on how to install a kitchen faucet like a pro – along with tips on when to call experts for help.
What You’ll Need
Before starting, gather all the tools and materials:
- New kitchen faucet kit (make sure it fits your sink holes)
- Adjustable wrench or basin wrench
- Screwdrivers (flat and Phillips)
- Plumber’s tape (Teflon tape)
- Bucket or bowl to catch water
- Towels or rags
- Flashlight or headlamp
- Plumber’s putty or silicone sealant
- Flexible supply lines (if not included in the faucet box)
If you don’t have these tools or aren’t confident working under tight spaces, you can always book services from Order a Plumber to handle the entire installation efficiently.
Step 1: Turn Off the Water Supply
Find the shutoff valves under your sink. Turn both hot and cold valves clockwise until they stop. Then, open the old faucet to release any remaining water in the lines. Place a bucket or towel under the sink to catch drips.
If you notice old or rusted valves that won’t close properly, it’s best not to force them. Order a Plumber can replace those valves safely and ensure your system is ready for a new faucet.

Step 2: Remove the Old Faucet
Use your wrench to disconnect the hot and cold water supply lines from the faucet. Keep a bucket ready for leftover water. Then, loosen and remove the mounting nuts holding the faucet to the sink. Lift the old faucet out from above and clean the area thoroughly to remove dirt and old sealant.
This step can be the hardest part, especially if the nuts are corroded or hard to reach.

Step 3: Prepare the New Faucet
Check the instruction manual that came with your new faucet. Each model may have slightly different assembly steps. Place the rubber gasket or plumber’s putty under the base to prevent leaks. If your sink has multiple holes, use the deck plate provided in your kit to cover unused ones.
Make sure all hoses and parts are ready and in the correct position before lowering the faucet into place.

Step 4: Install the Faucet
Insert the faucet lines and mounting shank(s) through the sink holes. From underneath, slide on the washers and nuts, then tighten them carefully. Use your wrench to snug them firmly but don’t over-tighten, as it can damage the sink. Ensure the faucet is straight and centered before final tightening.
If your faucet has a pull-down sprayer, feed the hose through the spout and attach the weight under the sink as shown in the manual.

Step 5: Connect the Water Supply Lines
Attach the hot and cold water lines to the shutoff valves. Use plumber’s tape on the threads to prevent leaks. Tighten connections by hand first, then give a slight turn with a wrench.
Once everything feels secure, double-check that the hoses are not twisted or kinked. If you notice signs of old, leaking valves or loose fittings, it’s wise to let our professionals at Order a Plumber inspect and fix them to avoid future leaks or water damage.

Step 6: Turn On the Water and Check for Leaks
Slowly turn the shutoff valves back on. Open the faucet and let the water run for about a minute. Check under the sink and around the base of the faucet for leaks. If you see any drips, tighten the fittings slightly. Wipe off excess putty or sealant from around the faucet.
If leaks continue or water pressure seems uneven, it might mean a connection wasn’t installed correctly. Instead of guessing, Order a Plumber can quickly identify and fix the issue, saving you time and frustration.

Step 7: Final Check and Cleanup
Wipe down your sink area, tighten any loose fittings, and make sure the faucet handle moves smoothly. Dispose of your old faucet properly and store any extra parts for future maintenance.
