Help! Can't connect concealed showe elbow

[robster]

Hi,

I've been refitting my bathroom - part of this is to install a shower with a concealed valve.

I've channeld the pipework into the thermalite block, and then overboared with Marmox. problem is, using the Grohe shower outlet elbow, and once the tiles are on (which I haven't done yet), the G1/2" connector on the back of the elbow will not reach the female side of the wall plate elbow concealed in the blockwork....how do I extend this to make it fit?

So as you can see, it's a Grohe design, not just a nipple.

The Grohe fitting instructions seem to suggest that the female part of the wall plate elbow (currently concealed in the blockwork) should be flush with the surface of the tiles, but I cannot see how I can acheive this - and I don't really want to be taking the Marmox off the wall again.

Any advice greatly appreciated.

Thanks

Depending on the gap between the front of the tiles and the socket in the wall I would use a running nipple and a half inch socket, if there isint enough space perhaps this would do ?

Thanks Picasso - perfect - little trip to TP, got a running nipple (that was fun asking for that!) and a socket - works a charm.

The simple things never seem to come to me easily!!
