I am trying to find a source for parts for a old Supamix shower unit.
The part I require is a small plastic piece with a brass lefthand threaded shaft running through it. This is used via the main control knob to control the water flow. I believe it may be called the plunger plate.
I have a drawing of the unit and parts I need plus photographs of the parts required if you can help me.
Thanks
