Concealed shower - hose connection leaking

[Jennie]

Hi all,
Wish I had X-ray vision.
My customer has an old concealed shower valve, with a concealed shower hose connection.
There is a dribble from the plastic housing around the shower hose connection (it's not the rubber sealing washer/etc on the hose). So maybe a crossed thread on the hose connection, or hairline crack in the plastic housing underneath the shroud, etc. Whatever, it's old and unsightly, and he'd like it upgraded.
Can I assume there would be a 15mm pipe popping out through the wall inside that housing, and that I might be able to fit something like this on it:

Once I start dismantling it, I'd be rather committed to seeing it through (preferably without ripping tiles off, if possible).

Thanks again for all your advice,

Jennie

Chances are Its a 1/2 in female thread behind tiles either a back plate elbow or female to copper

That looks like an old Mira response wall outlet, have a funny plastic elbow which may have spilt.
They ultimately go onto 1/2” nipple which would usually go back to 1/2” FI, but you don’t know what someone’s done.
To be safe just get a new Mira response wall outlet they are still available, then you can just go back as far a you need with new parts.

Sounds like the tiles are coming off then. Thanks for the confirmation.

You should be able to replace it without removing tiles, maybe stitch drill a little around if it’s been tiled tight - but the shroud will cover that.
