Concealed shower mixer with 3/4" connection to 15mm pip

Hi Guys,

have been reading all the relevant threads and can't find my situation, so if someone could point me in the right direction I'd be really appreciative.

I've just bought one of these new fancy concealed thermostatic shower mixer tap units ... it has two 1/2" connections (to the over shower head, and one to the hand held) which I intend to use wall plate elbows for (with 15mm pipe), but there are also two 3/4" connectors for the incoming feeds. I'm running 15mm in my bathroom and can't seem to find any wall plates that will take a 15mm pipe to connect to the 3/4".

I could use flexi connectors, but this is all going to be behind a stud wall and I'm not sure I trust those connections enough .... is there anything else out there that I can use?? Alternatively I could use a 22mm/15mm reducer in reverse, but that doesn't seem right either.

Do 15mm,3/4 connectors exist? If so, does anyone know where I'll find one easily??

Appreciate any informed, or even off the wall ideas

Thanks!!

Use a 15mm x 3/4" iron fitting.
What is the thread female/male ?

The thread is male.
I can't find a 15mm to 3/4 anywhere ... have you seen one? (and being picky I'd prefer end feed so I can be sure of no leaks, but obviously will settle for compression if that's all that's around)

Ahh, seco, you're amazing!!

I was only looking for elbows, but I could use something like this:

(compression, but it'll do the job)

Thanks mate!!

That's a MI you said you had a male thread so you would need a FI.

Is your thread internal or external ?

Damn, you're right .. I get excited too easily!!!

Here's a pic ... easier than words (and more accurate). Its the two middle connections I'm worried about.

So you need a female iron.
You prefer solder fitting.
