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:
Packaging
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.
Construction
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.
