Boiler Knobs !!

[Last Plumber]

Why do people break knobs off Vaillant boilers and then pretend they don't know anything about it ?
The evidence that they do is in the blu tac !

Is this a common occurrence throughout the land or just in this part of the world.

It could be the same fairies that make radiators just drop off of walls?..
