about Replace Moen Cartridge. First things first Make sure you have turned the main water valve to your house off.
Then Open a faucet (if possible at a lower level then the faucet being repaired) and make sure it stays open.
This will prevent any water that is getting past the valve or is just in the
lines from running in to the wall .
This is your basic Moen shower valve.
The same cartridge is used in Kitchen and lavatory faucets. This one is leaking Bad.

First remove the Handle. remove the plastic cover and remove the screw.
Note if you are repairing a Moen Kitchen faucet, you will need an Allen wrench key 7/16" to remove a set screw located behind the little Moen nameplate,
or just a blue and red hold cover, this can be removed with your thumb nail, once removed insert the Allen wrench and turn it counter
clockwise till the handle is loose enough to lift off of the cartridge stem.
Note: Removing the front plate is not necessary.
The faucet can be repaired with out removing the chrome plate.

There is a tool for removing the cartridge but I just put the handle back on and use it to pull the cartridge out.
Note: Sometimes a cartridge will not come out no mater what you do, If this happens you may want to stop and call a professional
This happens more when you have very hard water.

The old cartridge out. It is not worth the time and trouble to try to repair this cartridge. just replace it. In some cases Moen will replace if for free.
Before putting the new one in, clean out the inside of the faucet and apply a little plumbers grease to the walls of the faucet and on the new cartridge.
then slide it in. Make sure it goes all the way in.
I received an email today from a visitor that was installing a new cartridge in a Moen kitchen faucet, he said he followed
my instructions by adding a little more grease to the cartridge before installing it, as it turned out adding the extra grease was not a good thing,
because it caused the faucet to shut off by it's self do to the weight of the faucet handle. The cartridges come pre greased, so if you can get it to slid
back in with out adding the extra grease, you should do so especially if you are repairing a kitchen or lav faucet.

Note the position of the cartridge,
It must be in this position.
Replacing the pin. This must be done
right, It has to go straight through and into the bottom slot.

It must look like this all the way
in and not bent at the bottom. Now you are done. put back the sleeve, the chrome plate. and turn the water back on, But before you put the cover over
the handle screw test to see if the hot is on the left or not if it is on the right remove the handle and turn the stem 180% (you don't need to remove the
pin or cartridge to do this) Then put the handle back on and you are done. Good Luck. Feed back is very important

Your site was very
helpful; the photos were great and the step-by-step
instructions were excellent.
I am without question
an average homeowner, but I hate to call a plumber,
painter, carpenter, etc.
Thanks for your help in
this matter; I will be back. Best regards to you
in Alaska, Jim.
These instructions were right on the
money, I know nothing about plumbing but I was able to
change the cylinders in my tubs easily following these
instructions. THANKS! Very helpful Website.
I bought the
special tool to pull the valve and it came right out in
two pieces. Of course, I bought the wrong replacement
and had to make a second trip to Home Depot.
I had a bit
of a scare when I turned the main back on and the shower
just dripped when the valve was opened.
The sink had
pressure, so I know that wasn't the problem.
the shower head off and sure enough, the screen was full
of junk dislodged when I changed the valve.
works good now.
Thanks again for a very helpful website.
The guys at the store didn't know diddly. I'd been
putting off replacing the cartridge for months and
didn't use the bathtub in fear of having a problem
pulling out the cartridge. I have hard water and
it was difficult even after spraying it with vinegar.
Moen never told me of the cartridge pull but your site
I went to Home Depot and the first 2
people had no idea and the guy who supposedly knew about
plumbing came over and told me he needed the cartridge,
which I didn't bring because it was stuck.
asking him about a special tool to pull it out he
remembered and took me to the area with the pulls.
said he didn't have the one for Moen but I looked
through them all and found it easily.
If I didn't look
myself I would've had to call a plumber, and it's very
expensive to have him come to just remove the cartridge.
I really appreciate your site and the info you provide.
Plumbing can be very tricky for a novice and since I am
retired I prefer to do as much as I can, myself. Thanks
