Are all Moen Shower Cartridges the same?

Of course, not!

Moen shower cartridges aren’t all the same because the company uses different shower valves for the different showers. For example, when you hold both old and new shower cartridges, your mind is blown up, which seems to be the same length but apparently is not. The reason is that it offers a wide range of shower cartridges depending on their features, sizes, and compatibilities. Even Moen replacement parts are reasonably priced.

It is necessary to choose the right Moen shower cartridges that are compatible with the shower model and satisfy your individual requirements.

To make sure you choose the right Moen shower cartridge for your shower system, you should first consult the manufacturer’s website or a plumbing expert.

What Is the Difference Between Moen 1225 and 1225b Cartridges?

What Is the Difference Between Moen 1225 and 1225b Cartridges?

The main confusion that you might face when you see the model numbers of these two products is whether they are the same or if there is any difference or not.

Although most of their features are identical, there are some decisive factors that create some differences between the two. We have tried our best to clear your doubts by pointing out the clear distinctions between the two products:


Although, at first glance, the packaging of the two might seem to be the same, it has some differences.

As a matter of fact, the main difference between these two models lies in their packaging. The 1225 model comes in a retail pack, whereas the 1225b pack comes in bulk packaging. And the letter ‘b’ stands for bulk packaging.


How a product is constructed determines its life and longevity to a great extent. It also plays a huge role in its performance. If the construction of a product is made with quality items, then it lasts for a long time and gives the user a smooth experience.

On the other hand, if a product is made with cheap materials, it breaks down easily and does not perform well.

To ensure durability, the Moen 1225 cartridge is made of brass. This gives it a strong and durable finish. Brass is a material that does not get damaged easily.

Moreover, since the valve system will frequently come in contact with water, there is a possibility of rust formation. To prevent that, brass is a great material as it does not get rusted easily.

On the other hand, the Moen 1225b is made of plastic, which makes it lighter and easier to carry.

Process of Removal

Once the life of a cartridge ends, it needs to be removed to be replaced with another. What puts the Moen 1225b ahead of the 1225 model is its ease of removal.

Since the first model is made of plastic, it does not get stuck on the valve housing for which it is easier to remove.

On the other hand, the 1225 model is made of brass, and prolonged use causes calcium deposition on it. This makes it stuck on the valve housing, and you might have to replace the entire valve body to get rid of the brass cartridge.

How to Replace Moen Shower Cartridge?

How to Replace Moen Shower Cartridge
  • Working time: Estimated 1.5 to 2 hours
  • Skill Level: Beginner to Mid-Level
  • Estimated shower cartridge replacement cost: Minimum $20 to maximum $50

When you find leakage on the shower valves and can’t control the hot and cold water pressure, fix it or replace it as soon as possible. Before you begin to think about its replacement, you need to choose a Moen shower cartridge that is designed for both residential and commercial purposes.

Let’s see how you replace it and fix the leakage issue!

Tools you’ll need to replace the shower cartridge-

  • Flathead screwdriver
  • Phillips-head screwdriver
  • Needle nose pliers
  • Moen cartridge puller(If necessary)
  • Allen Wrench
  • New Moen replacement cartridge
  • Scraper
  • Rag

Instructions you need to follow-

Step 1: Shut the water off: Shut the main valve of the water supply and run the faucet for 30 to 60 seconds to reduce the water pressure and let it flow into your pipes. Cover the bathtub drain with a rag or tape if you have a hub in your bathroom.

Step 2:Remove the handle: Every handle is different; it’s better to research it online, but I can give you two more ideas about it. When the screw is attached to the shower handle, use a flathead screwdriver to force the cap to come off the shower handle. Another idea is to use an Allen wrench to lose the screw underneath and remove the handle when the shower handle has a single lever.

Step 3: Take off the escutcheon: While removing the shower handle, turn to take off the escutcheon, a piece of the ring- or sphere-shaped metal covering the shower’s wall hole. Unscrew it using a Philips-head screwdriver or choose the screwdriver depending on the screw hole.

Step 4: Remove the cartridge holding clip: Make sure to note where the cartridge clip is located to reinstall it precisely. Use needle nose pliers to grip the top of the clip, pull it straight up, and set it aside.

Step 5: Remove the old and leaky faucet cartridge: Now it’s time to pull the old, leaky cartridge so that you can use the Moen cartridge puller or not. Grip the adapter with the pliers, rotate it back and forth, and pull out the cartridge.

Step 6: Install a new replacement shower cartridge: Check the valve body’s interior for debris to see if it prevents the installation of the new shower cartridge. Use silicon grease to lubricate the rubber parts of the cartridge. Push it into the shower valve body after inserting it. Now reinstall the cartridge holding clip into a perfect position, then move a bit with the adapter or cartridge puller, and assemble the shower handle.

Step 7: Turn on the water for testing: Turn the valve after everything has been put in place to see if there is a leak. Check each fixture to make sure it is tight.

Safety Measures-

  • Turn off the water supply before disassembling the shower cartridge or you scald because of the hot water.
  • After the replacement, use caution when testing; turn the hot water supply on gradually so that you can turn it off before it gets hot enough to scald.
  • You may replace it alone if the leakage is small, but if it is complicated, call the home improvement experts.
