I'm feeling really stupid at this point. Hot side handle is loose.
No cap, no set screw. Tried unscrewing barrel but it just spins.
Please help.
Photos attached.
Thanks, Nick
That is the faucet and the dome needs to turn. The problem is after time the tend to seize up. (never did like that setup) Try soaking it in white vinegar or CLR. I have had to use a strap wrench on some.
