Homeowners, if you've got a leaky Moen Posi-Temp shower faucet, this repair kit has everything you need! The 1222 replacement cartridge is the exact match for most Moen single-handle tub and shower faucets. But here's the best part - it comes with the cartridge puller tool (104421) that you absolutely need to remove the old stuck cartridge. No more struggling with pliers and risking damage! You also get the handle adapter (116653) that often breaks during removal. The kit includes everything: new cartridge, puller tool, handle adapter, thermostat, retaining clip, and grease for proper sealing. The leak-proof design with black silicone gasket and included grease ensures no more drips after installation. The puller tool works with Moen 1200, 1222, and 1225 cartridges, made from anti-rust aluminum alloy that won't strip or break. Perfect DIY solution that saves you hundreds in plumber costs. Includes step-by-step visual guide so even beginners can handle this repair. Just make sure you have the Posi-Temp model (not the Moentrol) and you'll have your shower working like new in under an hour. Seriously, this kit makes what used to be a frustrating job actually manageable!
