A Moen faucet is a fantastic addition to any kitchen, with its stylish and sleek design. If you have one in your home, and it starts to leak, here is a comprehensive guide you can follow to repair your Moen kitchen faucet on your own. Don’t worry, it’s quite simple.

1. Prepare Your Tools.

Small Allen Wrench Set
Pliers
Hex Wrench
Plumber’s Grease
O-Ring Replacement
Moen Cartridge Replacement
Rug

2. Turn Off Water Source.
It will be easier to work if there’s no running water, and this prevents wastage, too. The water source valve is normally found under the sink or cabinet. Locate one or two valves attached to copper pipes or flexible tubes. Turn the valves or handles counterclockwise to shut the water down. Turn on the faucet handle to drain water trapped inside.

3. Open Up the Faucet.
Take the little indicator below the faucet handle, insert the right size of Allen wrench, and turn counterclockwise to loosen it. Remove the top of the faucet.

4. Reveal the O-Ring and Cartridge Tube.
Once the top of the faucet is removed, take off the nut to reveal the cartridge tube. Grab the hex wrench to loosen the nut. Remove the cartridge tube.

5. Determine Location of the O-Rings.
In most Moen faucets, the O-ring(s) are located on the bottom of the cartridge tubes, and also around the tube to which the water spout is attached.

6. Remove the Escutcheon or Crown.
To avoid destroying this section, cover it with a rug before inserting pliers or wrench to loosen it. Clean it by wiping it with the rug. You can also wash down any hard water build up by using 1 part water and 1 part vinegar.

7. Pull Out the Water Spout.
Take your rug and place it behind the spout so it absorbs any water trapped inside the spout. With your hands, slowly twist and pull up the spout to remove it.

8. Take the O-Rings and Bearings Off.
One by one take them off. Clean them up with a rug or water-and-vinegar solution. Once all the pieces are clean, you can replace the bearings and new set of O-rings.

9. Replace Bearings and O-Rings.
Put the bearing(s) where they should be. Coat the new O-rings with a modest amount of grease and place them where the old ones were.

10. Put the Spout Back On.
You should be able to twist the spout right and left with ease. This signals that the new O-ring replacements and the grease work properly.

11. Replace the Spout Crown Back On.
Twist it clockwise by hand and tighten rug-wrapped using your wrench or pliers. Don’t over-tighten it. Twist the spout again to ensure good mobility.

12. Replace the Upper Bearing and Nut.
Make sure that you place the upper bearing before the nut, or else you’re going to have a leak. Wrap it again with a rug and tighten it. Check the mobility of the faucet now and then as you put various parts on.

13. Place New Cartridge.
You don’t need to grease the tiny O-rings at the bottom of the cartridge. Insert the new cartridge, making sure that the nods on fits into the little holes properly. Once the cartridge is in place, put the nut back on and tighten using a hex wrench.

14. Place the Faucet Handle Back On.
Make sure that the handle is “open” so that it fits into the head of the cartridge properly. Tighten the handle using an Allen wrench, but not too tight. Put the faucet indicator back on.

15. Open Water Source and Test the Faucet.
See if there are still leaks or bad spout movement. The faucet should work much better now, and you just repaired a Moen faucet by yourself.
