Removing knob on bath overflow for raising plug

[Michael Chare]

My bath has a round knob on the overflow which you rotate to raise the plug.

How do I remove the knob?

[deckertim]

There should be a small grub screw on the underside of the knob. This could need an allen key to undo. The knob will then just pull off.

[The Natural Philosopher]

On mine, just pull off.

[EricP]

Brute force if no screw is apparent.

Mine pushes on easily but only my oldest son can remove it once it's been on for a while. :((

There's usually a hole in the underside. Either an allan key or a philips screw in the hole - loosen then pull off.
