The Moen M-2000 cartridge is a two-handle, non-diverter cartridge used in Moen's traditional and modern-style shower faucets. It features two separate handles, one for controlling water flow and another for adjusting the water temperature.

Step 1: Locate the Cartridge

First, you need to access the cartridge. Turn off the water supply to your shower and remove the showerhead or handheld shower (if applicable). Then, unscrew the escutcheon (the decorative plate covering the cartridge) using an adjustable wrench. Once the escutcheon is removed, you should see the cartridge.

If your faucet has a single handle, the cartridge will be hidden behind the handle. In this case, you'll need to remove the handle and the handle assembly to access the cartridge.

Step 2: Identify the Cartridge Type

Once you've located the cartridge, identify its type by counting the handles. A single-handle cartridge is either a Moen 1222 or a different model, while a two-handle cartridge is an M-2000.

If your faucet has a diverter, it's likely a 1222 cartridge. If there's no diverter, it's an M-2000 cartridge.

Additionally, you can look for the cartridge's model number or part number, usually etched onto the cartridge itself. This information can help you confirm the cartridge type and find the correct replacement part.

Regularly maintaining and identifying the correct replacement parts for your Moen shower faucet ensures optimal performance and longevity. By understanding the different types of Moen shower faucet cartridges and following the identification steps, you can easily find the right cartridge for your faucet and keep your shower running smoothly.

If you're unsure about any aspect of the identification process or need further assistance, don't hesitate to consult Moen's customer support or a professional plumber. Happy showering!
