Step-by-Step Installation Process
Here’s a detailed breakdown of how to replace your Moen kitchen sink faucet:
- Shut Off the Water Supply: Locate the shut-off valves under your sink. Turn them clockwise until they are completely closed. If you don’t have shut-off valves, you’ll need to turn off the main water supply to your house. Important: Test the faucet to ensure the water is completely off before proceeding.
- Disconnect the Existing Faucet: Place a bucket under the sink to catch any remaining water. Use an adjustable wrench to disconnect the supply lines from the old faucet. Use a basin wrench to loosen and remove the nuts that hold the faucet in place.
- Remove the Old Faucet: Carefully lift the old faucet out of the sink. Clean the sink surface around the faucet holes with a scraper or cleaner to remove any old putty or debris.
- Prepare the New Faucet: Follow the instructions included with your new Moen faucet. Usually, this involves attaching the supply lines and sprayer hose (if applicable) to the faucet body. Wrap plumber’s tape around the threads of any connections to prevent leaks.
- Install the New Faucet: Carefully lower the new faucet into the sink holes. From underneath the sink, attach the mounting hardware according to the manufacturer’s instructions. Make sure the faucet is securely tightened.
- Connect the Supply Lines: Connect the supply lines from the new faucet to the shut-off valves. Tighten the connections with an adjustable wrench.
- Turn On the Water Supply: Slowly turn on the shut-off valves. Check for leaks around all connections. If you find any leaks, tighten the connections or reapply plumber’s tape.
- Test the Faucet: Turn on the faucet and check for proper water flow and temperature. Check the sprayer (if applicable) to ensure it’s working correctly.
- Clean Up: Clean up any spills or debris. Dispose of the old faucet and packaging properly.
Common Mistakes to Avoid
Avoiding these common mistakes will help ensure a successful faucet replacement:
- Forgetting to Shut Off the Water: This is the most common mistake and can lead to a flooded kitchen.
- Overtightening Connections: Overtightening can damage the faucet or supply lines. Tighten connections snugly, but avoid excessive force.
- Using the Wrong Tools: Using the wrong tools can damage the faucet or make the job more difficult.
- Not Cleaning the Sink Surface: Failure to clean the sink surface can prevent a proper seal and lead to leaks.
- Skipping the Plumber’s Tape: Plumber’s tape is essential for creating a watertight seal.

Frequently Asked Questions (FAQs)
What type of faucet is easiest to install?
Single-handle faucets are generally considered the easiest to install due to their simpler design and fewer connections. Fewer parts mean less chance of error. While pull-down and pull-out faucets can be more complex, most come with detailed instructions that make the process manageable.
How do I know what size supply lines I need?
The size of your supply lines depends on the connections on your faucet and shut-off valves. Most modern faucets use 3/8-inch connections, but older homes may have different sizes. Always check the specifications of your new faucet and the existing shut-off valves before purchasing supply lines.
What do I do if I can’t turn off the water supply?
If you can’t turn off the water supply, you’ll need to shut off the main water supply to your house. This is usually located in the basement or near the water meter. If you’re uncomfortable doing this yourself, it’s best to call a plumber.
How do I remove a stuck faucet nut?
Penetrating oil can help loosen a stuck faucet nut. Apply the oil liberally and let it sit for a few minutes before attempting to remove the nut. A basin wrench provides leverage in tight spaces. If the nut is severely corroded, you may need to use a nut splitter or cut the nut off with a hacksaw.
What is plumber’s putty used for?
Plumber’s putty creates a watertight seal between the faucet base and the sink. It’s applied to the underside of the faucet base before installing the faucet. It prevents water from seeping into the sink deck opening.
How tight should I tighten the faucet connections?
Faucet connections should be tightened snugly, but not overtightened. Overtightening can damage the faucet or supply lines. Hand-tighten the connections first, then use an adjustable wrench to tighten them another quarter turn. Check for leaks after turning on the water supply.
What do I do if the faucet leaks after installation?
If the faucet leaks after installation, first try tightening the connections. If the leak persists, disassemble the connection, reapply plumber’s tape or replace the supply lines, and reassemble. If the leak is coming from the faucet body, you may need to contact Moen customer service for assistance or consider a replacement.
Can I reuse my old supply lines?
It’s generally not recommended to reuse old supply lines. Old supply lines can be corroded or damaged, which can lead to leaks. It’s best to replace them with new supply lines to ensure a reliable connection.
What is the best way to clean a new faucet?
The best way to clean a new faucet is with a soft cloth and mild soap and water. Avoid using abrasive cleaners, which can scratch the finish. Regular cleaning will help keep your faucet looking its best.
How long does it take to replace a kitchen faucet?
Replacing a kitchen faucet typically takes 1 to 3 hours, depending on your experience level and the complexity of the installation.
Do I need to hire a plumber to replace my faucet?
While hiring a plumber ensures a professional installation, many homeowners can successfully replace their kitchen faucet themselves. Following the instructions carefully and taking your time is key. If you’re uncomfortable with any part of the process, it’s best to call a plumber.
What is the warranty on a Moen kitchen faucet?
Moen offers a limited lifetime warranty on most of its kitchen faucets. This warranty covers defects in materials and workmanship. Be sure to register your faucet with Moen to activate the warranty.
