[Plumbing] How to remove covers over filters in mixer?

[Acyclo]

I'm trying to get off the covers over the filters in a thermostatic shower mixer/tap. It has no name on it, so I guess it's a cheap Italian jobby.

The covers have slots like they are intended for a coin edge. I made a 2p piece fit by grinding it thinner (oh-err, naughty) but no-go.

ANY ideas?

Attach the coin to a Molegrip and try again!

Are you able to stick some photos up so we can have a look at it?

 

[young Ed]

Here's the suckah.....

A large flat bladed screwdriver should do the trick, or a strong wood chisel.

Don't forget to grease the threads when you put it back.

ideally a large slotted screwdriver, shouldnt be too tight

Whats the large one on the side give you access to?

Dowse the screwhead in WD40 leave overnight and try unscrewing in the morning.

Dunno, the thermostatic mixer is in there somewhere.
