Removing the cover from a PIR

[Martin]

Hi,

I need to re-position a PIR, but it has no visible screws. I deduce the black casing unclips somehow, but I risk breaking something if I just lever it randomly around its rear edge.

The PIR looks very similar to this....

Does anyone know how to gain access to the screws which are holding it to a brick wall?

TIA

Can you lever the 'ears' apart and release the ball?

Thanks for the suggestion Peter. It doesn't look possible, and I don't think it will give access to anything useful. I'm pretty sure the cover is clipped into place after screwing the rest to the wall but, as you know, it's easy to break the clips if you can't see exactly where to lever the cover off.

I suspect I'll end up doing the "brute force and ignorance" thing... :-((

Thanks again.

Too true - and it will be obvious when you've broken it.

I replaced a toilet cistern inlet valve recently because I couldn't get it apart to get to the washer. Once it was off it 'simply' unscrewed and I could remove the bit of dirt... but by then I'd bought and installed a new one!!

Is it this one?

If so, maybe the seller might offer a suggestion?
