Thanks, That is definitely the item that I have. Looking at the diagram, I held down the "button" and then used a screwdriver to dislodge it and now it is out - thank you very much!
I have the pictured ideal standard shower knob and need to remove as I have got a leak. There is no obvious way to remove, has anyone come across this previously and knows how to remove? I "think" it might be to lever the front face plate, but don't want to risk damage if I am wrong
The water from the shower is leaking and I would like to remove the shower mixer to see if that is where the leak is coming from. However, its not clear how to remove the unit, does anyone know how I can remove?
I think its an ideal standard tap.
