How to Install a Moen Kitchen Faucet (Step-by-Step, 2026)
Installing a Moen kitchen faucet is one of the most DIY-friendly home improvement projects. Thanks to Moen's Duralock quick-connect system, most homeowners can complete the job in 20-30 minutes without a plumber. This guide covers every step from removal to first use.
Tools & Materials
- Basin wrench or Moen faucet installation tool
- Adjustable wrench
- Plumber's tape (PTFE)
- Bucket and towels
- Flashlight
- Channel-lock pliers (for stubborn connections)
Safety Notes
- Always shut off water supply before starting.
- Place a bucket under connections to catch drips.
- Do not overtighten connections, this is the most common cause of leaks.
Step-by-Step Instructions
Shut Off Water Supply
Locate the hot and cold shut-off valves under the sink. Turn both clockwise until fully closed. Open the old faucet to release remaining pressure and drain residual water into a bucket.
Disconnect the Old Faucet
Use a basin wrench to disconnect the supply lines from the old faucet. Disconnect the sprayer hose if applicable. Remove the mounting nuts holding the faucet to the sink deck. Lift the old faucet out.
Clean the Sink Deck
Remove old putty or caulk from the sink holes. Clean the area thoroughly so the new faucet sits flush. If your sink has 3 holes but your new Moen faucet is a single-hole design, use the included deck plate.
Install the New Moen Faucet
Feed the hoses through the sink hole(s). Seat the faucet and gasket on the deck. From underneath, hand-tighten the mounting hardware, then snug with a wrench. Do not overtighten.
Connect Water Supply Lines
Use the Duralock quick-connect fittings to attach the hot and cold supply lines. You should hear a click when the connection locks. No wrench needed for the quick-connect side.
Connect the Sprayer Hose
Attach the pull-down sprayer hose to the faucet outlet. The weight on the hose helps the sprayer retract smoothly. Make sure the hose moves freely without kinks.
Turn On Water and Test
Slowly open the shut-off valves. Check all connections for leaks. Run both hot and cold water for 1-2 minutes to flush the lines. Test the sprayer and pull-down function.
Common Mistakes to Avoid
- Forgetting to remove the aerator screen before flushing debris through new lines.
- Overtightening supply connections, which can crack fittings.
- Not checking that the sprayer weight has clearance to move freely.
Troubleshooting
Slow water flow after installation
Remove the aerator and clean any debris that may have entered during installation. Flush the lines without the aerator, then reinstall.
Drip at the base of the faucet
Check that the gasket is properly seated and the mounting nut is snug (not over-tightened).
Sprayer does not retract smoothly
Ensure the weight is properly positioned on the hose and that the hose is not kinked or catching on anything under the sink.
