Moen application and cartridge record
Moen 1225 Cartridge for Moentrol Shower Valves
Moen identifies cartridge 1225 for Moentrol tub and shower valve. Confirm the control layout, operating motion, and installed cartridge before buying; a similar-looking Moen trim is not proof of the valve or faucet beneath it.
Direct answer
The source-backed replacement relationship is Moentrol tub and shower valve → Moen 1225. This is a reference match, not a promise based on appearance: Identify the valve as Moentrol from its pull-on operation or documentation; a rotate-only Moen shower control is commonly the separate Posi-Temp platform.

Application relationship
Moen's product information places cartridge 1225 in the Moentrol tub and shower valve application. That relationship is the reason this part is considered here; finish, handle shape, and escutcheon style are not compatibility evidence.
Treat this page as a focused identification record for the cartridge inside the control. The visible faucet or shower trim can be replaced while the underlying valve or faucet platform remains unchanged.
Identify the control before ordering
First confirm single pull-and-rotate control. Operate the control and check for this pattern: Pull the handle outward for flow, then rotate it to adjust temperature. A different motion points to a different Moen platform even when the trim looks close.
Then verify the generation or internal construction. Identify the valve as Moentrol from its pull-on operation or documentation; a rotate-only Moen shower control is commonly the separate Posi-Temp platform. If documentation is available, use the model number and its official parts diagram rather than a photo-only match.
What the match does not establish
Do not substitute 1222 based on a similar shower trim: 1222 serves Posi-Temp, while this record concerns the pull-on Moentrol application. Moen has used more than one cartridge family across products with broadly similar silhouettes, so brand and handle count alone do not settle the choice.
Do not transfer this relationship to another fixture category without an official parts listing. The exact number on the package should match the verified replacement number, including every digit.
Removal-side confirmation
Shut off the appropriate water supplies and relieve pressure before exposing the cartridge. Photograph handle orientation and retaining hardware as each piece comes off; those details help preserve the original setup.
Compare the removed cartridge's body, stem, seals, and retention method with Moen's official material. If the old part is damaged or incomplete, stop and identify the faucet or rough-in valve from its markings instead of guessing from the fragment.
Questions
Before you remove or replace the part
Does every Moentrol tub and shower valve use Moen 1225?
No blanket fit claim is intended. Moen supports the stated application relationship, but revisions and similarly named products make model, motion, and installed-part checks important before purchase.
Can I identify the cartridge from the handle style?
Not reliably. Handle style is a screening clue only. Confirm single pull-and-rotate control, the operating motion, and the cartridge or valve documentation.
Should I remove the old cartridge before buying?
When the model or valve platform cannot be documented another way, removal-side inspection is the strongest check. Shut off water first and preserve the orientation and retaining pieces for reassembly.
