Have have a leaky faucet. I don't know what brand. It came with the
house. It is the ball single handle. I have been able to remove
everything down to the white whatumacallit with the piece sticking up
on the back side and the flat on the left side. I can't seem to get
this off. HEEELLLLLPPPP. How does it come off?
I'm almost positive that I need to replace the inner core piece that
lies under this white thing

C'mon now, you cant' expect much of a reply to a question with so few
facts. If you post a pic you will get more replies.
