Falling at the First (Fix) Fence…

[G and J]

So, we are rabidly getting everything shoved into the walls to get ready for plasterboarding.  
 

The plumbing side of things is a simple ‘radial HEP2O, no joints in the walls’ type affair.  Isn’t that just so simple (in theory).  And then I open the box of the Aqualisa thermostatic shower gubbins.  
 

Last time I fitted such things was in ‘91, and they are still going (with a facelift on one and new cartridges on both, but still).

 

So this time I discover that I have a 15mm compression joint on the control inlets.   Q: Can I put 15mm HEP2O with an insert straight in?  I’m sure I’ve done that before but is it a good idea?  Is it better to convert to copper for the last few inches?

 

Secondly, the outlets appear to be suited to installations where one has access to the back of the shower wall. Bugger.  
 

For fitting without access to the back of the wall the instructions just say put a 1/2 inch connector in the wall then later screw the shower hose bit into it with some PTFE tape.  Sort of like an external tap connector.  (See instructions below). 
 

Q:  is that what people really do? Will that even work? Will I end up with a wobbly rain head pointing at the ceiling?

 

Guidance very much appreciated folks.

You use outside tap type angled backplates for the outlets to the handset and rainfall head

Do exactly this (please).

Not true of every single one I've ever fitted, and that's "more than one"

Thank you Nick.  So the PTFE tape amount is adjusted till the shower head is pointing vaguely downwards…

 

Hmmm.  That means all the weight is on that 1/2inch thread.  Scary.  But then, I am good at worrying about the wrong things.

Or just listen to Nick.

The annoying thing is that it literally trebles the number of buried joints.

…..made of solid brass….

 

Are you planning on any WWF slam down matches in the shower? Or just bathing as we do here; 2 adults, 4 very unsympathetic children now teens hammering these things. 
 

Still as good and functional as the day I put these in, 7 or 8 years ago now iirc.

 

Cheap as chips shower arm (380mm long for my 800mm wide bath) and the rainfall head was £8.99 on eBay. Died after 6 years of use / abuse, another £8.99 one went on. Looks like a £100 one, so sue me

More money left over for beer.

 

Chill out, it’ll be perfectly fine

If only.  If I had nothing on the build worrying me I’d worry about what I didn’t know about that I should be worrying about lol
