Old Fashioned Bathtubs Any Advice To Stop A Hot Water Faucet From Squeaking?

Any advice to stop a hot water faucet from squeaking? - old fashioned bathtubs

I have an old claw foot bath. Normally, the pressure and water temperature is good, but lately, the pressure of hot water a little weak (only in the bathtub, sink and the pressure of the bath is very good. In Bad pressure cold water is also OK), and it is this terrible scream from the noise when you are back on the bathtub faucet. You're only two days ago. Suggestions on what and how to solve this problem? I would like to renovate the bathroom, but the rent. Thank you a bunch!
