Shower Outlet

[ron99]

I have a thermo mixer shower manifold which i have just located in the wall. i have piped the hot and cold to the manifold. my problem is the Outlet from the manifold. I have a chrome elbow which the shower head flex connects to, the other end of this elbow is 15mm tap male. how do i insert this elbow thru a tile tighten the lock nut behind the tile, and connect up to the manifold 3/4\\\" bsp female, just cant see a way of getting spanners to the fittings. the bathroom will be tiled when i finish the plumbing and get the wall skimmed

If the outlet from the mixer is buried in the wall you need to put pipe between it and a wall outlet thingy. Your pipe at the new outlet from the wall will have a 1/2" female appearing at the hole in the tile.

For this sort of thing

to screw into.

The chrome elbow has a 2" long male parallel thread to take a female tap fitting unlike the one pictured above (short female). my problem is securing this to the manfold outlet behind when the tile is in place.
how would i get to the fittings to tighten?.

thanx

backplate elbow secured to the wall.

Thanx for the reply.

The chrome elbow has a long parrallel thread and is baggy in the backplate elbow, i could place a fibre washer inside the b/p elbow but i believe general movement of the shower hose could affect this joint over time creating a leak behind the tile.

I generally cut the thread to length required, to get a nice fit.

Thanx for the advise.

The thread on the chrome elbow looks like it needs to seal on something with it not being tapered, is it practice to put a fibre washer into the b/p elbow to achieve this?, and if i cut the chrome thread and its not a completely square cut, would that not give me a leak as it wouldnt be square on the fibre washer?.

thanx again.
