Repairing the Moen Chateau L4621 single-handle lavatory repair, older style that takes the 1200 or the 1225 cartridge.
Moen L4621 in an older home.
The handle comes off using an Allen wrench and this is what is below the handle. The phillips screw gets removed and then the lever mechanism is lifted off.
The black fitting unthreads counter clockwise, then the transition collar is lifted off giving access to the retainer clip that is lifted upward, allowing the white holder to be removed. You can now remove the cartridge.
And two more versions of the L4621
