Wall plate elbow will not be flushed with tile - confused

[Koch]

Hi,

I have installed a wall plate elbow (see attached the only photo I have of this) for shower hose elbow outlet, but the problem I have is that after 10mm WP board+grout and tile (assume 15mm WCS), the elbow will be short of the tile outer edge by 10-15mm. This will be an issue as how would I know hose outlet elbow is fixed watertight and incase of leaks, it will be hard to detect. I can’t bring the wall plate elbow outward any further as it can be seen in the sketch, the pipe is set at max it can be or it will be level with the WP board.

See attached photo of the wall plate.

Is it okay for the plate to not be flush with the tile or if not, how can I make it flush? The hose outlet elbow can be imbeded in the tile as it’s has the same diameter as the wall plate but again, I don’t feel safe that way.

I’d appreciate your advise.

Thanks

use locktite 55 and you will be ok

Sometimes, my back plate elbows end up an inch or more below finished tiled surface, as builders/tilers may have to square off the walls.
I always put a 1/2" plug in the elbow so that I can leak test the pipe to it. I also leave it (and all other pipework) pressurised with water as this 'alerts' other trades when they go through a pipe with a screw or nail 

To get the plug out of the elbow, I use a tubular spanner and then use various length rad extensions (1 or more, depending on recessed depth) to bring the outlet flush with the tiles

Use good quality 15mm femail irons with plenty of locktite 55 to bring the mount forward. Had one recently had 2 femail irons in the wallplate!!

Hmm I've never thought of using those rad tail extensions for that before. They do have a use after all... Good call!

Thanks @muggles, it's something I tried a few years back as I had a few on the van and they come in more increments than female irons... They sometimes also have a prefitted rubber sealing gasket on the male end and the female end has either an internal keyhole for a rad-rachet spanner or a narrower external hex than a female iron.
Methinks I should claim it as one of @dilalio's Top Tips... Maybe I'll suggest it elsewhere

....or use a 15mm x 1/2” female coupling discarding the nut and olive.

Cant you just put a 10/15mm spacer behind the elbow to bring it out?

Repipe it from underneath, with a couple of street elbows, and you can pack it out 10/15mm.
