How do I change the cartridge in my Moen shower faucet?

Assuming you have a Moen Posi-Temp shower valve, the process for replacing the cartridge is as follows: 1. Remove the handle. There is a small set screw in the center of the handle that needs to be removed.

Once this is done, the handle will pull straight off. 2. Remove the temperature limit stop. This is a small cap located just below the handle.

Use a small flathead screwdriver to remove it. 3. Use a wrench to remove the retaining nut. This is located under the temperature limit stop.

4. Pull out the old cartridge and replace it with the new one. Make sure the O-rings are in place and lubricated before inserting the new cartridge. 5. Re-assemble the shower valve in the reverse order.

That’s it! You should now have a brand new cartridge in your Moen shower faucet.

How do you remove a Moen shower cartridge without the tool?

If you need to remove a Moen shower cartridge and don’t have the tool, you can use a pair of pliers. First, shut off the water to the shower. Then, remove the handle by unscrewing the set screw with a hex wrench or Allen key.

Next, use the pliers to remove the retainer nut, which is located under the handle. Finally, pull out the cartridge.

How do I know which Moen shower cartridge I need?

If you’re looking to replace your Moen shower cartridge, the process is actually pretty straightforward. The first thing you’ll need to do is identify which model shower cartridge you have. Moen shower cartridges are designed to fit a specific set of valves, so they’re not all interchangeable.

Once you’ve determined which model you have, the next step is to find the right replacement cartridge. The Moen website has a handy tool that can help you find the right replacement cartridge for your shower. All you need to do is enter your model number and it will bring up a list of compatible cartridges.

If you’re not sure which model number you have, you can also find it printed on the side of your existing cartridge. Once you’ve found the right replacement cartridge, the next step is to install it. This is a pretty simple process, but if you’re not comfortable doing it yourself, you can always hire a professional.

With a new Moen shower cartridge in place, you can enjoy years of reliable performance from your shower.

How do I stop my Moen shower from dripping?

If your Moen shower is dripping, there are a few things you can do to try to fix the issue. First, check to make sure that the showerhead is tightened properly. If it is, then try cleaning the showerhead with vinegar to remove any built up mineral deposits.

If that doesn’t work, then you may need to replace the showerhead.


If your Moen bathroom shower faucet is giving you trouble, it might be time to replace the cartridge. This is a relatively easy do-it-yourself project that anyone with basic plumbing skills can handle. To replace the cartridge, start by shutting off the water supply to the shower.

Then, remove the handle by unscrewing it from the shower valve. Next, use a wrench or pliers to remove the retaining nut that holds the cartridge in place. With the retaining nut removed, the old cartridge should easily slide out.

Take it to your local hardware store to find an exact replacement. To install the new cartridge, simply reverse the steps you took to remove the old one. Once the new cartridge is in place, turn on the water supply and test the shower faucet to make sure it’s working properly.

If all goes well, you should now have a functioning shower faucet!
