Mixer tap valve stuck

[zoothorn]

Hi chaps,

 

small issue preventing water going UPWARDS via hose, to a shower head, from a bath mixer tap pair.
 

The valve thingy between the taps, is stuck. How to release it?

 

Thanks, Zoot

Does it lift, or turn, normally? Usually these lift and are held up by water pressure, then they drop back to bath position by themselves. 
 

The part you pull should unscrew if you turn it with a spanner (lefty loosey) and then you can WD40 it, or search for a matching replacement.

There are flat spots here for the spanner to grip onto.

If a hard water area, soak it in Viakal or similar once removed to disolve the limescale.
