Hep2o push fit for exposed shower

[phatboy]

Hi all,

 

This was super simple until I really thought about it.  I am going to run my 15mm plastic Hep pipe down the wall to the shower position.  The wall is concrete, so needs chasing.

 

As the pushfit elbows are quite chunky, I will need to dig fairly deep into the wall where they go, and will use copper out of each so I can use compression on the shower unit.

 

Is this the right approach?  Chase the wall about 25mm deep for the pipe, but then increase it up to about 50 - 60mm to fully bury the elbow?  Or is there some other kind of fitting I could use?  I considered copper with sweated elbows, but it would mean a joint in the loft, which with the manifolds is exactly what I've wanted to avoid.

 

Many thanks!

I fit these into the shower valve, and add 1/2" x 3/4" brass bushes if needed.

Then no need to convert to copper  Done bucket loads of jobs this way, perfectly acceptable and robust option.

Use those to set you back, if the knuckles of the fittings need to be back a bit to sit in your chase

Thanks Nick, but I’m struggling to visualise!

 

The shower is an exposed type (this or similar: https://www.duravit.co.uk/products/bathroom_faucets/shower_systems.com-en.html?product=7158157 ), where as your first link in my mind would be used on a recessed valve?

 

The 135 degree, do you have a picture of this setup? My brain just isn’t doing its stuff after a weekend of bathroom building! 
 

Thanks

My bad, I assumed a concealed unit.

At least I’m not going insane then!

 

But thank you - this advice will be relevant for the other 2 bathrooms, which are having concealed valves.
