I've replaced faucet washers before but never in this house (2.5 yrs in this old house). The knobs in the shower are hot and cold with the faucet in the middle for the batch. The knobs are mounted to the wall which is tiled. I removed the cap and unscrewed the screw in the middle of the knob, but cannot get the knobs off the faucet ends. I don't want to pry too hard. I've tried WD-40 but nothing seems to loosen them.
Ideas?
Thanks,
G.
