I found a message that was identical to the problem that I am having. The problem is the reply with the solution was nowhere to be found. The message was from 1998 and they thanked Terry for his help so I know the solution was given. Below is the text of the original post:

Terry, Our shower waterflow will not turn fully turn-off. The shower fixture is a Moen with a push/pull handle. we removed the cover and see a brass stem/cartridge, where do we go from here to remove to make repair or replace. The unit has to be over 10 years old. There is a chrome sleeve over the stem.. is the chrome sleeve removable to get to the stem/cartridge.. Thanks for a great service.....
Water turned off in California.
Can someone either point me to the original answer or generate a new one?
