How to remove flange? Brand?

[Average_Joe]

Hi. I have a leaking showerhead (won't shut off completely) and think I need to replace the stem or gasket/washer. But when I took the handle off-the flange is attached behind the wall. Do I need to use a deep socket or can the flange come off somehow? I hope the original builder (25 years old) didn't tile it behind the wall. Any idea what brand? Thanks!

Still hoping someone might have experience with this?

that is an Old Moen 2 handle Valve.
Look for a Moen 1248 cartridge

That chrome tube should pull off. look inside tube and see if you see any fine threads. if not it should pull off.

That valve had a defective design. Surprised it made it all these yrs.

There maybe and extension to the cartridge inside the brass bonnet.

I looked for a diagram but could not find one. good luck.
