Preparing to Disassemble Your Moen Kitchen Faucet

Before you start to disassemble Moen kitchen faucet, proper preparation is essential. This ensures your safety and protects your plumbing system.

Gathering Your Tools and Materials

Having the right tools makes the job easier and prevents damage to your faucet. Here’s a list of what you’ll likely need:

• Adjustable wrench: For loosening and tightening nuts.
• Screwdrivers (Phillips and flathead): For removing handles and other parts.
• Allen wrench set: Often needed for specific Moen handle types.
• Penetrating oil: To loosen stubborn screws or parts.
• White vinegar: To dissolve mineral deposits.
• Clean cloths or rags: For wiping up water and cleaning parts.
• New Moen cartridge (if replacing): Make sure it matches your faucet model.
• Plumber’s grease: For lubricating O-rings and cartridges.
• Basin wrench (optional): For reaching difficult-to-access nuts under the sink.
• Flashlight: To see clearly in tight spaces.

Shutting Off the Water Supply

This is the most important step! Find the shut-off valves under your sink. There should be one for hot water and one for cold water.

1. Turn both valves clockwise until they are completely closed.
2. Turn on the faucet to relieve any remaining pressure in the lines. Let the water run until it stops completely.
3. Place a bucket under the faucet in case any residual water remains.

Identifying Your Moen Faucet Model

Knowing your faucet model is crucial when ordering replacement parts. Moen faucets have various designs, and cartridges aren’t universal. Look for a sticker or stamp on the faucet body, under the sink on the supply lines, or in your original documentation. If you can’t find it, take clear pictures of your faucet from different angles and compare them to images on the Moen website or contact Moen customer service for assistance. Identify Moen faucet model precisely before ordering parts.

Step-by-Step Guide: Disassembling a Moen Kitchen Faucet

This section provides general instructions. Specific steps may vary depending on your faucet model. Always consult your faucet’s specific instructions if available.

Moen Faucet Handle Removal

Moen faucet handle removal varies based on handle style. Here’s how to approach different types:

1. Single-Handle Faucets (Set Screw):
   • Look for a small set screw on the side or back of the handle, often hidden under a decorative cap.
   • Use a small flathead screwdriver or Allen wrench to loosen the set screw.
   • Once loosened, pull the handle straight up and off.
2. Single-Handle Faucets (No Set Screw):
   • Some handles are held in place by a threaded connection.
   • Grip the base of the handle and gently twist it counterclockwise.
   • If it doesn’t budge easily, try using penetrating oil.
3. Two-Handle Faucets:
   • These handles usually have a decorative cap on top.
   • Pry off the cap with a small flathead screwdriver.
   • Remove the screw underneath the cap.
   • Pull the handle straight up and off.

Accessing the Cartridge

Once the handle is removed, you can access the cartridge.

1. Remove the Handle Adapter or Sleeve:

   • After removing the handle, you’ll likely see a metal or plastic sleeve or adapter.
   • This part covers the cartridge.
   • It may be threaded or held in place by a retaining clip.
   • Unscrew or carefully pry off the sleeve/adapter.

2. Removing the Retaining Clip (If Applicable):

   • Some Moen faucets have a horseshoe-shaped retaining clip that holds the cartridge in place.
   • Use a small screwdriver or pliers to carefully remove the clip. Be careful not to damage it, as you’ll need to reinstall it.

Removing the Moen Faucet Cartridge

Removing Moen faucet cartridge is the next crucial step.

1. Use a Cartridge Puller (Recommended):

   • Moen cartridges can be difficult to remove, especially if they’ve been in place for a long time. A cartridge puller is a specialized tool that provides leverage and helps you extract the cartridge without damaging the faucet body.
   • Follow the instructions that come with the cartridge puller.

2. If You Don’t Have a Cartridge Puller:

   • Grip the stem of the cartridge with pliers.
   • Gently twist the cartridge back and forth while pulling upwards.
   • Be patient and apply steady pressure.
   • If the cartridge is stuck, try spraying penetrating oil around the cartridge and let it sit for a few minutes.
   • Avoid using excessive force, as you could break the cartridge inside the faucet body.

Inspecting and Cleaning the Faucet Body

With the cartridge removed, take the opportunity to inspect the faucet body.

1. Check for Mineral Deposits:

   • Look for mineral buildup inside the faucet body, especially around the cartridge opening.
   • Soak a cloth in white vinegar and wrap it around the affected area. Let it sit for at least 30 minutes to dissolve the deposits.
   • Use a small brush or toothbrush to scrub away any remaining residue.

2. Inspect for Damage:

   • Check the faucet body for cracks or corrosion. If you find any significant damage, it may be necessary to replace the entire faucet.

Fixing Leaks: Replacing the Cartridge

Replacing the cartridge is often the solution to a fix leaky Moen faucet.

Installing the New Cartridge

1. Lubricate the Cartridge:

   • Apply a thin coat of plumber’s grease to the O-rings on the new cartridge. This will help it slide in smoothly and create a watertight seal.

2. Align the Cartridge:

   • Make sure the cartridge is oriented correctly. Most Moen cartridges have a specific alignment, often indicated by a mark or notch on the cartridge body.

3. Insert the Cartridge:

   • Push the cartridge firmly into the faucet body until it is fully seated.

4. Reinstall the Retaining Clip (If Applicable):

   • Snap the retaining clip back into place to secure the cartridge.

Reassembling the Faucet

1. Reinstall the Handle Adapter or Sleeve:

   • Screw or snap the handle adapter or sleeve back into place.

2. Reattach the Handle:

   • Slide the handle back onto the faucet stem.
   • Tighten the set screw or screw the handle into place, depending on the handle style.
   • Replace the decorative cap (if applicable).

Testing for Leaks

1. Turn on the Water Supply:

   • Slowly turn the shut-off valves under the sink counterclockwise to reopen the water supply.

2. Check for Leaks:

   • Carefully inspect the faucet body, handle base, and spout for any leaks.
   • Run the faucet in both hot and cold positions and check for leaks.
   • If you find any leaks, tighten the connections or double-check the cartridge installation.
