I think mine is a 94 Moen Posi-Temp kind of valve. It is dripping a bit but not a huge amount yet so I can wait a few days troubleshooting this.
The newer one I heard use 7/64 hex bit to screw and unscrew, but one of the older one I have in the house seems to use something around 2mm, 1.5mm, 1/16, or something like that. It hasn't been touched for decades and I'm using white vinegar to remove the calcium deposit in the hole where the set screw go between the handle and the valve's "flat" area.
The allen wrench seems to only free wheeling inside the set screw, or won't go in at all. So to remove it, some people on the internet recommend just drilling it out and replace the handle / kit completely. It is probably the final solution if nothing else work, but I want to ask all the people here if there's another way before I go that far.
Anyone seen this and what do you guys do to fix it?
