Fitting outside tap

A compression elbow instead of a solder one would, but like this...

Doesn't that still needs soldering?

Not with a compression elbow.

And you'll need a check valve inside on the supply to the tap if you don't already have one.

Something like this?

I'd need it to fit into this backplate:

How can I check if I have one?

The tap itself has one (https://www.screwfix.com/p/outside-tap-with-double-check-valve-15mm-x/37241)

Something like this?

No, just a normal elbow, with a bit of pipe between it and the tap wall elbow.

Not allowed on a new tap installation.

Have a look around inside for something like this feeding the tap.

It's impossible.

The pipe goes inside the wall then goes down below ground to join the pipes coming from the mains tap. It's already plastered etc so I can't see the pipe inside (judging from it it doesn't seem I have one of those as I doubt they fitted one in the wall or under the floor)

 

[Dedekind]

Actually what I do have is this, which is already outside. Is it the one I need?

 

[denso13]

Is it the one I need?

No, you need a double check valve internally fitted.

Internally as in inside the house? How can I do this is the pipe is inside the render and then goes under the wall and under the floor to where the main tap is? (basically the mains rise up to the tap, then from there it goes below ground again to feed the cold water to the rest of the house, including this tap).

Pictures of inside the cupboard showing your pipework would help.

Yes. Unfortunately to comply with the regulations you need to find a way or you can't have a tap in that location.
