How To Determine Correct Moen Cartridge

Do you need to replace your Moen shower valve cartridge but dont know the difference between all of the Moen replacement cartridges?

Honestly, Moen is the best faucet company when it comes to simplicity. They have worked extremely hard to not only make high-quality products but keep their replacement parts streamlined.

Ask any plumber, and theyll attest to just how easy it is to find replacement parts and repair shower valves for Moen products.

Moen 1222 vs 1225 Replacement CartridgesThe biggest difference that you’ll find with Moen shower valves is the Moen 1222 vs 1225 replacement cartridges.

The 1225 is the updated version of the original 1200 single handle cartridge with a brass shell and brass piston. That is the original cartridge that Al Moen invented decades ago. The Moen 1225 has a clear plastic shell with a brass piston inside of it

The biggest difference between the Moen 1222 vs 1225 cartridges is how the shower valve handle turns the water on.

Shower valves with the Moen 1225 cartridge are turned on by pulling the handle out and then adjusting the temperature by turning the handle to the left or right for hot or cold water.

So, you could say that the Moen shower valves which have the Moen 1225 cartridge offer volume control. You can effectively pull the handle only as far out as you need which is a nice feature.

Pressure balancing is an important feature of a shower valve as it reduces the risk of you getting scalded with hot water if someone flushes the toilet while you are showering. The pressure balancing of the Moen 1222 Posi-Temp cartridge has a spool in it that effectively closes down the hot water side if it senses a reduction in flow from the cold water side, preventing you from getting scalded with hot water.

Shower valves with the Moen 1222 cartridge are turned on by rotating the handle only. Unlike the Moen 1225 cartridge, the 1222 cartridge does not have volume control.

So, you simply rotate the handle counter-clockwise to open the flow of water and find your desired temperature. With the Moen 1222 you cannot control how much water comes out of the shower valve.

Are The Moen 1222 & 1225 Cartridges Interchangeable?


While the Moen 1200 and the Moen 1225 cartridges are interchangeable, the Moen 1222 Posi Temp cartridge is absolutely not interchangeable with the Moen 1225 or 1200.

In fact, there isnt any part that is interchangeable between the Moen 1222 vs 1225 replacement parts. The handles dont fit, the shower plates dont fit, nada!

Thats why its so vital that you determine which Moen shower valve you have before buying any replacement parts. And the best way to do this is by removing your shower trim and inspecting your shower valve to determine if you have the Moen 1222 vs 1225 shower valve cartridge.

And if you are someone who wants volume control but you already have a Moen 1222 Posi Temp valve, you cannot just replace the cartridge to the Moen 1225 cartridge to achieve volume control.

You will need to replace your existing shower valve with an entirely new shower valve manifold with one that has volume control like the Moen Moentrol shower valve, which is a pressure balancing valve that takes the Moen 1225 cartridge.

There is absolutely NO difference between the Moen 1222 vs 1222B replacement cartridges.

They are both the replacement part cartridge for the Posi Temp Moen shower valve. They are made from the same parts, the only difference is their packaging and model number.

The “B” in the 1222B model number stands for Bulk. Thats it! Its simply the part that Moen sells to contractors in case packs. The 1222 is the one that youll commonly find in your hardware stores.

The Moen 1222 vs 1222B parts are both coming off the same Moen replacement cartridge production line at their factory in North Carolina. The only difference is the packaging. So dont get caught up on asking yourself what the difference between Moen cartridge 1222B vs 1222 is.

For additional information on Moen products visit and select the type of product you are repairing. The guide will contain repair details, troubleshooting and specific information on assembling handles associated with that style of product.

Preparation: The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.


How do you tell which Moen valve I have?

Look closely at the handle buttons that were attached to the shower valve. Typically, “Moen” will be written in the middle of the “Hot” and “Cold” buttons. If you do not see this, the handle buttons have been replaced, or the “Hot/Cold” button is a lever (wall escutcheon).

Are there different Moen cartridges?

Are The Moen 1222 & 1225 Cartridges Interchangeable? NO! While the Moen 1200 and the Moen 1225 cartridges are interchangeable, the Moen 1222 Posi Temp cartridge is absolutely not interchangeable with the Moen 1225 or 1200.
