What is the Moen 1225 Cartridge?
Imagine your faucet as the barista of your bathroom or kitchen. It mixes hot and cold, then serves it up at your perfect temp. The Moen 1225 cartridge is the inner mechanism making all that magic happen.
This cartridge is designed for Moen single-handle faucets, and it’s been a staple since the 1980s. It’s reliable, affordable, and—spoiler alert—super easy to replace.
When would you need to replace it?
- Your faucet’s leaking
- You’ve lost control over the water temperature
- The handle is tough to move or feels loose
- You’re feeling like an empowered human being who fixes things
Moen 1225 Cartridge Replacement: Step-by-Step
Let’s get right to it. If you’ve got 15 minutes, a screwdriver, and a sense of mild determination, you’re golden.
Tools You’ll Need:
- Flathead screwdriver
- Allen wrench
- Adjustable wrench or pliers
- Replacement Moen 1225 cartridge
- Needle-nose pliers (optional, but they make you feel legit)
- Plumber’s grease (if you want the buttery-smooth install)
Step-by-Step Breakdown:
- Turn off the water supply – Unless you’re into geysers in your bathroom.
- Remove the faucet handle – Usually a screw under a cap; use your Allen wrench.
- Take off the retaining clip or nut – This holds the cartridge in place.
- Pull out the old cartridge – Wiggle and pull straight up.
- Insert the new Moen 1225 cartridge – Match the orientation with the old one.
- Reassemble everything – Tighten, cap it, done.
Pro tip: Apply a little plumber’s grease to the O-rings on the new cartridge. Your faucet handle will glide like a figure skater.
What Does 1225 Mean?
Great question. It’s Moen’s model number for this specific type of single-handle cartridge. Think of it as the sneaker size for your faucet. You wouldn’t cram into a size 9 if you’re a 12, right?
How Do I Know If I Have a Moen 1222 or 1225?
This one stumps a lot of folks. Here’s a cheat sheet to save you some grief:
| Feature | Moen 1225 | Moen 1222 |
| Valve Type | Two-handle-style in a single-handle faucet | Pressure-balanced shower valve |
| Use Case | Sink faucets, older tub faucets | Modern shower valves |
| Handle Motion | Up and down, side to side | Rotates left to right |
| Interchangeable? | Nope | Nope |
So if your faucet handle moves up and down, it’s likely a 1225. If it rotates, it’s probably a 1222.

Are Moen 1222 and 1225 Interchangeable?
Short answer: No.
Think of it like trying to wear your friend’s prescription glasses. Similar shape, but you’re gonna have a bad time.
These cartridges are engineered for different valves. Forcing a 1225 into a 1222 setup is like putting a square peg in a round, leaky hole.
Difference Between Moen 1225 and 1225B
You might stumble across a Moen 1225B and think, “Is this a trap?”
Don’t worry—it’s not.
| Model | Difference |
| 1225 | Standard retail version |
| 1225B | Bulk packaging for pros |
That’s it. Same cartridge, same function. Just different packaging. If you’re not buying a 12-pack for your contractor cousin, go with whichever is cheaper.
Are Moen 1200 and 1225 Interchangeable?
Kind of—but it’s complicated.
The Moen 1200 is the older brass version. The 1225 is its modern plastic successor.
You can swap one for the other, but here’s a quick comparison to help you decide:
| Feature | Moen 1200 | Moen 1225 |
| Material | Brass | Durable plastic |
| Longevity | Slightly higher | Lighter weight |
| Availability | Rare | Easy to find |
| Cost | Higher | More affordable |
Verdict: Go with the 1225 unless you’ve got a nostalgic thing for brass.
Moen 12801 Cartridge vs 1225: What’s the Deal?
If the 12801 pops up, you’re dealing with a variant of the 1225. It fits in the same valve but is made for specific models.
| Cartridge | Compatible With | Notes |
| 1225 | Most 1-handle faucets | Universal classic |
| 12801 | Certain Roman tubs | Slightly different build |
Check your faucet model. If it says 12801 in the manual, stick with it. Otherwise, 1225 is your all-around go-to.

Let’s make this crystal clear. If you spot any of these red flags, it’s time to upgrade:

You could call it the James Dean of faucet cartridges—tough, reliable, iconic.
