Any suggestions for getting the knob unstuck? Normally, pulling up
the knob diverts the water flow from the taps to the shower. TIA.
They often operate only when the water is already flowing - have you tried
this? If so - suggest trying to get a shock of water to unstick the valve by
opening taps suddenly (when it isn't expecting it!!!!). Also try thumb over
tap.
At a guess its limescale. Try a limescale remover around the knob (oooh
errr missus). If not, turn the water off & take it apart, then soak in
limescale remover.
