I'm trying to replacing a moen cartridge (1222b) on a moen shower. I took off the handle and there is a metal handle adapter. I removed the screw in the middle of the adapter and cannot remove the metal handle adapter. Can someone help. I do have a pic of it but I can't attach it to this post.

Try this, moen.com (http://www.moen.com/consumersupport/installation/moen0133/moen0133.cfm), it says "not found" but click on "customer support", videos and manuals.

Grasp with pliers and pull. If it really won't come off get a faucet handle puller and use it to pull the adapter. It is just stuck from crud and corrosion.

Once you remove the adapter, toss it - and get Moen handle Milo
