Moen Kitchen Sink Faucet Removal: A Step-by-Step Guide for Beginners

By Lauren Holland

Updated November 2026

Moen kitchen sink faucet removal is a manageable weekend job if you work in the right order. You will shut off the water, disconnect the supply lines, release the mounting hardware and lift the old faucet out of the sink deck. Plan on roughly an hour, most of it spent working under the sink where space is tight.

Before You Start: Shut Off the Water and Gather Tools

Locate the two shutoff valves under the sink, one for hot and one for cold. Turn both clockwise until they stop. Then open the faucet to relieve pressure and let residual water drain. Place a towel and a bucket in the cabinet because a small amount of water will still come out of the lines when you disconnect them.

Gather these tools before you begin:

Flashlight or headlamp
Adjustable wrench and basin wrench
Plumber’s putty or a bucket for catching drips
Towels and a shallow pan
Phillips screwdriver

Step-by-Step Removal Process

Disconnect the Supply Lines

Place the bucket beneath the connections. Using an adjustable wrench, loosen the compression nuts on the hot and cold supply lines, then unscrew them by hand. Keep a firm grip on the shutoff valves so the valves themselves do not turn. If you have a side sprayer, detach its hose from the base and pull the weight through the deck.

Remove the Mounting Nut and Hardware

Reach up under the sink and find the mounting nuts or the plastic locking nut that secures the faucet to the sink deck. A basin wrench reaches these far better than a standard wrench. Turn counterclockwise until the nut releases, then remove any washers and mounting studs. Check whether your model uses a deck plate; if so, lift it out too.

Lifting the Faucet Off the Sink

Once the hardware is free, go back up top and lift the faucet straight up. Old sealant or putty can make it stick, so work it gently side to side rather than yanking. Note the orientation of the spout and any gaskets so the replacement sits correctly. Clean the sink deck with a plastic scraper and a mild cleaner before installing anything new.

Common Mistakes and Tips

Skipping the shutoff valves. Even a few seconds of unexpected water flow can soak the cabinet floor.
Forcing a stuck nut with excessive torque, which can crack plastic components or damage the sink.
Forgetting the side sprayer hose or the pull-down weight, which can snag when you lift the unit.
Discarding small parts. Keep washers, gaskets and mounting hardware together in a labeled bag.
Taking photos before disassembly, which makes reassembly much easier.

Recommended Gear

Basin wrench: Its angled jaws reach mounting nuts in the tight space behind the sink basin. View on Amazon
Headlamp: Hands-free light is essential when you are lying under the cabinet. View on Amazon
Plumber’s putty: Useful for resealing the deck if the old sealant has hardened or the new faucet needs a base seal. View on Amazon

FAQ

Do I need to turn off the main water supply?

Usually no. The individual shutoff valves under the sink are enough for a faucet swap. If those valves are old or do not close fully, shut off the main supply at the house.

Can I remove the faucet without taking off the sink?

Yes. Most faucets are removed from above and below the deck with the sink still installed. The only time the sink needs to come out is if it is damaged or you are changing the sink too.

What if the mounting nut is rusted?

Apply penetrating oil and wait 15 to 20 minutes before trying again. If it still will not budge, consult a licensed plumber to avoid damaging the sink or cabinet.

Conclusion

Removing a Moen kitchen sink faucet comes down to shutting off the water, disconnecting the lines, releasing the mounting hardware and lifting the unit out. Work slowly, keep your parts organized and clean the deck before installing a replacement. Once the old faucet is out, you are ready for the new one.
