I have an older Moen shower kit. It’s a Legend series on a Moentrol valve. It uses a 1225 cartridge. I noticed the new shower handles Moen sell for their latest Moentrol valves now use a different cartridge - something called M-Pact cartridges which don’t look like the old 1225 at all. My question: Is it still possible to fit this fixture on an old Moentrol valve?
