Moen has a limited life time warranty on their faucets to the original owner. If your faucet is dripping or leaking around the base you may not need to replace it, you may just need to replace the cartridge and o-rings. If you call Moen they will send you the parts for free. Replacement parts may be obtained by calling 1-800-289-6636 (Canada 1-800-465-6130).
Once your parts have arrived you will need to know how to replace them.
These instructions are for a kitchen faucet, but, most steps can be applied to any Moen faucet, with the exception of disassembly of the control handle.
- Allen wrench
- Adjustable ( Cresent) Wrench
- Standard (flat) blade screw driver
- Phillips screw driver
- Replacement parts
First things first… shut off the supply valves under the sink and open the faucet to release any pressure.
To remove the cartridge from your kitchen faucet, use a flat-headed screwdriver to gently pry the cover from the top of the handle. Then using a Philips screwdriver, unscrew the handle screw and pull the handle off the faucet (some faucets may have an allen style screw).
Remove the collar by hand and lift off . Next, lift off the black plastic pivot retainer.
Then unscrew the stop limit lever.
Using a crescent wrench,loosen the retainer nut and then twist off by hand.
Pull off the washer from the cartridge (it it has one) and use pliers to remove the retaining clip.
2- Cartridge Removal
You are now ready to remove the old cartridge.
I like to use a cartridge puller.
Oh, and see how nicely the parts are lined up on the counter… this makes it easier when you are putting it back together.
This cartridge puller is made by Danco and is about $12.00, well worth it if the cartridge is old and really stuck.
You can also use the white plastic tool that comes with the new cartridge stem. It looks like a cap on the end of the new cartridge, pay attention to how it is seated when you pull it off and place it in the same position on the old cartridge you are removing ( position it so that it straddles the ears ).
Use pliers on the white plastic tool to loosen the cartridge by rocking and/or twisting back and forth. Once it feels loose, remove the white plastic tool, grasp the cartridge stem and pull it straight out of the valve.
If your cartridge is really stuck, you may want to spray it with PB Blaster, my favorite, penetrating oil and let it soak for a few minutes.
3- Cartridge Reassembly
You can now install your new cartridge. If it came with a small package of lubricant , smear it on the cartridge (some come pre-lubricated). I like to add a little PTFE based lubricant. It’s not toxic, water proof and helps to reduce corrosion and mineral build up.
Next push the cartridge straight down into the valve, making sure that the ears of the cartridge are lined up precisely with the retaining clip notch.
Re-install the retaining clip and replace the washer onto the cartridge.
Finish reassembling the faucet by reversing the rest of the steps that you followed to remove the old cartridge.
Once everything is back together, turn on the water and test for leaks…and to make sure you have the hot and cold where they should be, if you need to reverse the sides continue reading.
Reversing Hot & Cold
If you need to reverse the sides for Hot and Cold water first remove the handle. Next, rotate stem exactly 180 degrees and replace the handle.
Note: If your faucet is leaking at the base, you will also want to remove the spout by pulling it straight up and replace the to O-rings on the valve body.
Pat yourself on the back for another job well done and… You didn’t need a man to fix it!
Until next time…
Life is simple… Enjoy the journey!
