I am trying to change these shower knobs/valve/stem as they are leaking from there base and there is so much salt stains.
I live in a condo where there is no access panel. To get water supply turned off, to try anything, off whole building supply needs to be off. This gives me anxiety as I can't request for longer shut off time for trial and errors. I can't seem to find any brand name. Please guide me in any way possible. Thank you!
