Hi All

Just purchased a shower mixer, it is the horizontal standard bar type which sits outside on shower wall.

It is quite heavy and i am wondering how to support it securely. It only has two chromed nuts (hot/cold) and then two threaded pieces which are 22mm dropping to 15mm.

There is about a 10mm gap when these are screwed together, there is also no internal rubber washer for sealing ???

I plan on using the 25cm/2.7m upvc cladding panels in the shower but see no way of supporting it securely ??

The wall will need to be studded for pipes/cladding. How can i make sure it is securely fixed ??

I think those threaded parts are named 'Z threads' or something..lol It looks as if there is a flat on 22mm side for support and they are offset..

Cheers

I used backplate elbows, fix them in the wall at the correct spacings and the Z threads screw in andcan be adjusted for any fine tuning getting the centers correct

What are backplate elbows mate, i presume i could fix these to the concrete wall then have a length of 15mm pipe which protrudes with z screws behind the fascia panel.

Still a bit confused though, what is the purpose off the z screws as tgey don not give any support ???

Would i not have the fixed main support elbows, tiny length of 15mm, another adapter to connect to z screw ?? Then the z screw behind the panel and surface mount chrome nut on other side...

If studding out i presume the distance between the wall and panel needs to be small as possible to avoid any play/movement...So stub out with 2x2"

Wish i bought a flush mount and just fixed it to wall

......

AAAAAAArrrrgggghh

Backplate elbow is what they use for outside taps that screw on the wall.

You have to make it all up dry, to the finish tile face, then screw the backplate to the wall/stud, connect the pipes behind, finish the front of and screw it all together.

The offset allows you to make fine adjustments.

Cheers scruff.

So what protrudes through the tiles, 15mm pipe or z threads ?

How do i connect the z threads to the 15mm, some sort of compression end ?

Just looked at pics of them it looks like the z screw goes directly into the backplate elbow.

The wall panel/tiles then sit between the z screw and chromed shower nut, so the flat of the z screw is behind the panel/tiles.

There will be not much thread of the z screw protruding though to get a few turns of the lock nut ??

Got loctite 55

The thread sticks out to take the backplate and nut.

As I said you need to make it all up dry, so it all matches up, with the tiles.

So the only visable bit on tile side is a bit of thread from the z screws ?

Yes, you need enough for the backplate and the nut.

As I said set it all up dry, then the Z things allow final adjustments to get the valve level etc.

Got everything and been playing , but just don't why the z screws are offset ??? If straight it's simply case of getting them plumb and screwing in.

When you adjust it throws the bar of level ????

Also there is only a gap of about 3mm when chromed bar nut is fully screwed in and this needs to take tile/board ??

My Grohe i fitted last was a lot simpler just fix to wall at correct depth and job done.

Only has this as thought it would be easier, looks as if it involves a lot of faffing with loctite 55 to get it right ??

Only get about x2 turns of bar nut when chrome cover plate is screwed on ??

This is the brand - http://www.plumbworld.co.uk/architeckt- ... 3224-15911

So what should i set the backplate centres at and what size hole do i nedd through tiles peeps ?

Cheers

It should all fit really.

You can always buy some long brass space nipples if you have problems, it will make it easier. perhaps.

Scruff yo been a star mate. Now this i could fit easily but not sure what bits i would need. may just pop into plumbers and ask. My backplates are end fill.

Also to lengthen it is simply done with longer 15mm.

Only problem doing it like that is making sure you don't damage (twisting) the copper when you make the front on.

True never thought of that, could break a solder seal. Still don't understand why they offset them, for me it seems more awkward...lol

Don't they make a type that are not offset ?
