After dewinterizing this year I have a slow dribble from the shower even when it is turned off. I think maybe the cartridge needs to be replaced. I've gotten this far:
I think the next step is to remove the pin, but it's behind the shower wall. I see other references in this thread
to this problem which suggest removing the whole thing, I can't figure out how to do that.
Also, as far as I can tell there's no way to access behind the wall with my layout.
Could somebody point me in the right direction?
