Overview of Moen 158084 and 1222 Shower Faucet Cartridges

Let’s start by highlighting that Moen shower faucet cartridges are renowned for their quality, reliability, and ease of installation. The Moen 158084 and 1222 cartridges share these traits but have unique features that separate them from each other.

Moen 158084: The Powerhouse

The Moen 158084 is designed to replace the 1225 cartridge used in many of Moen’s single handle shower faucets. This includes popular models like the Chateau, Latitude, Kingsley, and Mason.

The 158084 is strictly a temperature control cartridge. It allows you to adjust the mix of hot and cold water to get the desired shower temperature. The 158084 does not control water volume or pressure.

Some of the key features and specifications of the Moen 158084 cartridge include:

  • 1⁄2 inch diameter, with 35⁄64 inch stem
  • 1225 replacement cartridge
  • Works with Posi-Temp pressure balancing system
  • Single lever temperature control
  • Brass and stainless steel construction
  • Shuttle design provides smooth handle control
  • Durable plastic stop limits cartridge rotation

The 158084 cartridge is a direct swap for the original 1225 cartridge. So installation is fairly straightforward in most cases. The cartridge uses a retaining nut to hold it in place. Replacing it involves:

  1. Turning off water supply lines and removing handle and trim plate
  2. Removing the retaining nut
  3. Pulling out the old cartridge and inserting the new 158084
  4. Replacing the retaining nut and turning water back on to test

The 158084 is a good medium price point cartridge option. It costs more than a basic replacement cartridge but less than the 1222. The 158084 works well for controlling shower temperature. Just keep in mind it does not adjust volume.

Pros of Moen 158084

  • It offers exceptional resistance to water pressure fluctuations, making it suitable for high-usage households.
  • Its non-metallic construction prevents corrosion, thus ensuring a long lifespan.
  • With its well-detailed installation guide, even novices will find it easy to install.
  • Smooth temperature control performance
  • Durable brass and stainless steel construction

Cons of Moen 158084

  • Controls temperature only, not water volume
  • May need adaptor for some faucet models
  • More expensive than basic replacement cartridge
  • A few users have reported slight difficulties when removing the cartridge from the valve.

Moen 1222: The Dependable Performer

The Moen 1222 is a popular replacement cartridge designed for the company’s 1255 valve system. This includes faucet models like the Brentwood, Caldwell, Eva, and Rothbury.

Unlike the 158084, the 1222 controls both water temperature and volume. This allows you to adjust the temperature with the handle’s rotation and the pressure/flow with the handle’s vertical movement.

Here are some of the key details on the Moen 1222 cartridge:

Moen 1222 cartridge
  • 1⁄2 inch diameter, with 3⁄8 inch stem
  • 1255 valve replacement cartridge
  • Single lever controls both temperature and volume
  • Ceramic disc design for smooth handle control
  • Dual-action cartridge shifts vertically for flow
  • Stainless steel and plastic internal parts
  • Roll-pin ends for secure installation

The ceramic discs in the 1222 provide for smooth faucet operation over years of use. This cartridge also incorporates a number of internal seals and springs to control water flow and prevent leaks.

Installing the Moen 1222 cartridge takes a bit more effort than the 158084. It uses roll-pin ends to hold it in place rather than a threaded nut. Replacing this cartridge involves:

  1. Shutting off water lines and removing handle and trim
  2. Using pliers to detach retaining clip and pull roll-pin ends off
  3. Removing old cartridge and inserting new 1222
  4. Reattaching roll-pin ends and replacing trim

Due to the more complex design, the 1222 cartridge costs more than the 158084. But it also delivers more functionality, with both temperature and volume control. This cartridge is best suited for faucets designed for the 1255 valve.

Pros of the Moen 1222:

  • Controls both temperature and water volume
  • Ceramic disc design for smooth faucet operation
  • Durable stainless steel and plastic construction
  • Designed for 1255 valve faucets like Caldwell

Cons of the Moen 1222:

  • More difficult installation process
  • Significantly more expensive than basic cartridges
  • Only works with 1255 valve faucets

Key Differences Between Moen 158084 and 1222 Shower Faucet Cartridges

While the Moen 158084 and 1222 cartridges are both part of the Posi-Temp series and share certain characteristics, they also have their unique differences. This section dives deeper into their key distinctions.

  • Material and Durability

One of the most significant differences between the two cartridges lies in their construction.

The Moen 158084 is non-metallic, which makes it highly resistant to corrosion.

This quality boosts its durability and ensures it lasts longer, making it a great choice for households that require frequent showers or high-pressure usage.

On the other hand, the Moen 1222 is made of plastic, which, while also robust and durable, might not stand up to high pressures as well as the 158084.

Nonetheless, the 1222 is designed to provide a reliable performance and is more than capable of handling regular residential water pressure.

  • Performance and Water Pressure

When it comes to performance, both cartridges are designed to maintain consistent water temperature, even if the water pressure changes.

However, due to its robust design, the Moen 158084 might be a better choice for homes with high water pressure or fluctuating pressures, as it’s better equipped to handle these conditions.

The Moen 1222, while also capable of maintaining a consistent temperature, is better suited for normal residential water pressures. For most households, the 1222 would be an excellent and cost-effective choice.

  • Price

Cost is another factor where the two cartridges differ. Generally, the Moen 158084 is priced a bit higher than the 1222. However, the price difference is justified by its enhanced robustness and higher resistance to pressure fluctuations.

The Moen 1222, being more affordable, offers excellent value for its price. It delivers reliable performance, which has made it a popular choice among many households.

Ultimately, the choice between the Moen 158084 and the 1222 largely depends on your specific needs and the conditions in your home. Both are excellent products that deliver on their promises, but understanding these differences will help you make the best choice for your shower.

When comparing the two, the decision between the Moen 158084 and the 1222 largely depends on individual needs and preferences. While the 158084 offers more robustness and can withstand higher pressures, the 1222 provides more affordable, reliable performance.

Now that we’ve covered the general characteristics, pros, and cons of the Moen 158084 and 1222 cartridges, let’s move on to some frequently asked questions.

Determining the Right Cartridge

So which cartridge is the best choice for your Moen shower faucet? Here are some tips on determining which model you need:

  • Look at the existing cartridge – The easiest way is to check the cartridge you’re replacing. The 1225 uses the 158084 and 1255 uses the 1222.
  • Check compatibility charts – Moen provides detailed compatibility charts listing which cartridges fit which faucets.
  • Assess required functionality – If you need both temperature and volume control, the 1222 is required. The 158084 only handles temperature.
  • Consider difficulty of install – The 158084 is generally easier to install than the 1222, an important factor for DIYers.
  • Review price difference – The 1222 costs around 50% more than the 158084. If your faucet only needs temperature control, the 158084 can save money.

Knowing the specifics of your existing faucet and shower valve can help narrow down which replacement cartridge will work.

And determining the required functionality and difficulty of installation can guide you to the best model.
