Banging noise and no pressure

[Clikmaster]

Hello,

I have a bathtub in my upstairs bathroom, installed about 10 years ago. The cold water is working fine. About 5 years ago, I started having issues with hot water. If I turned it up to the max, I used to hear loud bangs in the wall and the pressure would go down. Now, there is no more noise nor pressure at all. I get a tiny little stream of hot water only, even if it is turned on all the way. Any idea what I should be doing to fix this?

Thanks.

Sounds like a bibb washer, cartridge, stem or debris in the valve body problem. Post a pic of the valve.
