Shower Valve Replacement for American Standard N 1130-1
I have been struggling with this stuck shower faucet valve for hours. It seems to be an American Standard from what I can read on the escutcheon plate. I have not been able to identify any similar model in their catalog. I have looked in HD plumbing dept and didn't see anything similar. Do you know what this valve is? Can you tell me how to replace it? I would like to turn my water back on, but the valve leaks inside the wall now when the water is on. Thank you.
The escutcheon plate that appears to read: American Standard
