Gathering Your Plumbing Tools
Before you begin, make sure you have the necessary plumbing tools on hand. Having everything ready will make the process smoother and prevent frustrating trips to the hardware store.
Essential Tools for Faucet Removal
- Adjustable Wrench: This is your primary tool for loosening and tightening nuts and fittings. An adjustable wrench is versatile and can fit various sizes.
- Basin Wrench: This specialized tool is designed to reach nuts that are in tight, awkward spaces, often found under the sink where the faucet is mounted. It has a long shaft and a pivoting jaw to grip these hard-to-reach nuts.
- Phillips Head Screwdriver: You might need this to remove any decorative caps or screws holding the faucet handle in place.
- Flathead Screwdriver: Useful for prying off decorative caps or gently separating parts if needed.
- Pliers: Channel-lock pliers or slip-joint pliers can be helpful for gripping and turning stubborn parts.
- Bucket or Towels: To catch any residual water that may drain from the pipes.
- Safety Glasses: Protect your eyes from debris or drips.
- Work Gloves: To improve grip and protect your hands.
- Penetrating Oil (Optional): If parts are corroded or stuck, a penetrating oil can help loosen them.
- Wire Brush (Optional): For cleaning any mineral deposits or rust from the mounting area after removal.
Preparing for Removal: Shutting Off the Water
The very first and most crucial step is to disconnect water supply to the faucet. This prevents any water from flooding your workspace once you start disassembling.
Locating and Shutting Off the Shut-Off Valves
- Find the Shut-Off Valves: Look under your kitchen sink. You should see two valves, one for hot water and one for cold water, connected to the flexible water supply lines that lead to your faucet. They usually have small, oval-shaped handles.
- Turn Off the Water: Turn the handles of both the hot and cold water valves clockwise until they are fully closed.
- Test the Water Flow: Turn on your faucet to ensure the water supply has been completely shut off. Let any remaining water drain out. The faucet should only drip for a moment before stopping.
If you can’t find individual shut-off valves under your sink, or if they are old and don’t work, you will need to shut off valves for the entire house. This is usually located in your basement, crawl space, or near your water meter.
Removing the Faucet Handle
Most Moen kitchen faucets have handles that are designed for relatively easy removal. The method can vary slightly depending on the specific Moen model, but the general principle involves accessing a retaining screw or clip.
Steps to Remove the Faucet Handle
- Identify the Handle Mechanism: Look closely at your faucet handle. Many Moen handles have a decorative cap that hides a screw. This cap is often found on the front or side of the handle.
- Pry Off the Decorative Cap: Use a small flathead screwdriver or a utility knife to gently pry off the decorative cap. Be careful not to scratch the finish of the faucet or sink.
- Locate the Handle Screw: Once the cap is removed, you’ll see a screw. This is typically a Phillips head screw.
- Remove the Screw: Use your Phillips head screwdriver to unscrew and remove the screw. Keep it in a safe place, like a small container, so you don’t lose it.
- Pull Off the Handle: With the screw removed, you should be able to gently pull the handle straight up and off the faucet body. If it’s stuck, a gentle wiggle might help. Avoid excessive force. Sometimes, a bit of penetrating oil can help loosen a stubborn handle.
Table: Common Moen Handle Attachment Types
| Attachment Type | Description | Removal Method |
|---|---|---|
| Screw Under Cap | Most common; screw is hidden beneath a decorative cap. | Pry off cap, unscrew, then lift handle. |
| Set Screw (Allen) | Some modern or commercial-style faucets use a small set screw, often on the side. | Use an Allen wrench to loosen the set screw, then lift the handle. |
| Clip or Pin | Less common; a small pin or clip might secure the handle. | Look for a visible pinhole; use a small screwdriver or punch to push out the pin. |
Detaching the Spout
The spout is usually the next part to come off. Again, the exact method depends on your Moen faucet model. Some spouts are secured by a nut or screw from underneath, while others might simply lift off after the handle and other components are removed.
Steps to Detach the Spout
- Check for Retaining Screws or Nuts: Look underneath the faucet body, where the spout meets the main unit. You might see a nut or a screw holding it in place.
- Loosen the Retaining Nut/Screw: Use your adjustable wrench or basin wrench to carefully loosen and remove the nut or screw. Turn it counter-clockwise.
- Lift or Slide Off the Spout: Once the retaining mechanism is removed, the spout should lift straight up or slide off the faucet body. If it’s stuck, try gently wiggling it or tapping it lightly with the handle of your screwdriver. Be careful not to force it, as you could damage the faucet base or sink.
- Special Case: Swivel Spouts: For swivel spouts, there might be a large retaining nut that holds the entire spout assembly in place from underneath the sink. You’ll need your basin wrench for this.
Disassembling the Cartridge and Body
This is where you’ll often need your basin wrench the most. The cartridge is the internal mechanism that controls water flow and temperature. It’s typically held in place by a large nut or bracket from underneath the sink.
Steps to Disassemble the Cartridge
- Access the Faucet Mounting: Get under your sink and look at where the faucet is attached to the sink or countertop. You will see the threaded shanks of the faucet body, along with water supply lines.
- Locate the Mounting Hardware: The faucet is usually secured by one or more mounting nuts. These can be large plastic or metal nuts that screw onto the threaded shanks of the faucet.
- Loosen the Mounting Nut(s): This is where your basin wrench shines. Fit the jaw of the basin wrench onto the mounting nut and turn it counter-clockwise to loosen. This can be challenging due to the confined space. You might need to reposition the wrench multiple times.
- Remove the Mounting Hardware: Once the nuts are loose enough, you should be able to unscrew them by hand or with your adjustable wrench. There might also be a mounting bracket that needs to be removed.
- Disconnect Water Supply Lines: Before you can fully remove the faucet, you’ll need to detach the flexible water supply lines from the faucet shanks. Use your adjustable wrench to loosen the nuts connecting the supply lines to the faucet. Be prepared for a little residual water to drip out, so have your bucket or towels ready.
- Remove the Faucet from Above: With all the mounting hardware and supply lines disconnected from underneath, go back to the top of the sink. You should now be able to lift the entire faucet assembly straight up and out of the sink holes.
- Addressing the Cartridge (If Necessary for Faucet Removal): In some Moen faucet designs, the cartridge needs to be partially or fully removed before the entire faucet can be lifted away. Look for a retaining nut or clip that holds the cartridge in place within the faucet body.
- Retaining Nut: If there’s a large nut holding the cartridge, use your adjustable wrench or a pair of pliers to unscrew it counter-clockwise.
- Retaining Clip: Some Moen cartridges are secured with a U-shaped clip. You can usually pry this clip out with a flathead screwdriver.
- Disassemble Cartridge: Once the retaining mechanism is removed, you should be able to pull the cartridge out of the faucet body. You might need to use pliers to grip it and wiggle it out.
Table: Common Moen Faucet Mounting Systems
| Mounting Type | Description | Tool Requirement | Difficulty |
|---|---|---|---|
| Single Nut | A large nut that secures the entire faucet shank from below. | Basin wrench, adjustable wrench | Moderate (access can be tight) |
| Two Nuts | Two nuts, often on separate shanks, securing the faucet. | Basin wrench, adjustable wrench | Moderate to High (access can be very tight) |
| Bracket System | A metal or plastic bracket with screws or clips holding the faucet. | Screwdriver, pliers | Moderate |
| Compression Ring | A specialized ring that tightens to secure the faucet. | Basin wrench | High (can be difficult to grip) |
Cleaning the Faucet Base and Sink Area
Once the old faucet is removed, take the opportunity to clean faucet base areas and the surrounding sink or countertop. This is the perfect time to tackle any grime, mineral deposits, or old plumber’s putty that might have accumulated.
Tips for a Clean Workspace
- Scrape Away Old Putty/Caulk: Use a plastic scraper or an old credit card to gently scrape away any old plumber’s putty or silicone caulk. Be careful not to scratch the sink’s surface.
- Remove Mineral Deposits: For stubborn mineral deposits, a solution of white vinegar and water can be effective. Let it sit for a few minutes before scrubbing with a soft brush or cloth.
- Wipe Down the Area: Use an all-purpose cleaner or a mild soap and water solution to thoroughly clean the sink deck where the faucet was mounted.
- Inspect for Damage: While you’re cleaning, check the sink or countertop for any cracks or damage that might have been hidden by the old faucet.
Replacing Your Moen Faucet
If your goal is to replace faucet, now is the time to prepare for the new installation. Have your new faucet ready and read its specific installation instructions. The process of installing a new faucet is essentially the reverse installation of removal, but with added steps like applying plumber’s putty or silicone sealant.
Key Steps for New Faucet Installation
- Prepare the New Faucet: Assemble any parts of the new faucet that require it, following the manufacturer’s instructions.
- Apply Sealant: Apply a bead of plumber’s putty or silicone sealant around the base of the new faucet where it will meet the sink or countertop. This creates a watertight seal.
- Position the New Faucet: Carefully feed the new faucet’s shanks and supply lines through the mounting holes in the sink.
- Secure from Below: From underneath the sink, install any washers, gaskets, and mounting nuts that came with the new faucet. Tighten them securely using your basin wrench and adjustable wrench, but avoid over-tightening, which can crack the sink.
- Connect Water Supply Lines: Attach the new flexible water supply lines to the hot and cold water shanks of the faucet and to the respective shut-off valves. Hand-tighten first, then use your adjustable wrench to snug them up an additional quarter to half turn.
- Turn on Water and Test: Slowly turn the hot and cold water shut-off valves back on. Check all connections for leaks. Turn on the new faucet and let the water run for a minute or two to flush out any air and debris. Check again for leaks under the sink.
Troubleshooting Common Issues
- Stuck Mounting Nuts: If a mounting nut is extremely corroded and won’t budge, you may need to use a penetrating oil and allow it to soak in, or in extreme cases, carefully cut the nut off with a small hacksaw or oscillating tool, being very careful not to damage the sink.
- Stubborn Cartridge: If the cartridge won’t pull out, some Moen cartridges have a specific tool for removal. Otherwise, gentle prying with a screwdriver or pliers might be necessary. Moen often sells replacement cartridge removal tools.
- Leaking After Installation: If you notice leaks after installing the new faucet, re-check all connections. Ensure supply lines are tightened properly and that plumber’s putty or silicone sealant created a good seal at the base.
