My friend has a 25 year old Moen Chateau Shower valve with a 1225 cartridge. It leaks and I am worried that when I attempt to pull the cartridge with a recommended puller called ONA that I will have to use the secondary puller on that tool. I have pulled many Moens but never one this old and I have heard stories that they can be a _itch to remove if too much calcium has built up inside the valve body. Any of you guys had experience with this project? TIA for your help.
