In order to lift the plug in our bath, you have to turn this big chrome knob to the left.
Our chrome knob has come away from the bath slightly, our twin boys (aged 2) like to put their fingers in the gap, but then cry when their fingers get nipped.
How do I tighten this?
There's a hole underneath/at the bottom of the chrome knob, I've stuck a screwdriver in the hole but can't find anything that may help.
Many thanks.
