Plan for concealed shower

[deasonuk]

Hi, 

 

I was posting in the thread about extending stud. 

Maybe more appropriate in this section is whether the options are actually suitable!

 

Does this work for concealed valve to a minimum line fitting?

Yup, just you’ll be routing out the back of the plasterboard to get pipe and fittings covered, particularly problematic if you’re using push fit plumbing instead of soldering copper pipes. 
 

If you can set it back another 10-15mm that would make plumbing much easier, and allow you to use push fit.

Nick when can you start on my job as I'll probably be finished by June at this rate lol. 

I see what you mean about piping, I'll be overlapping the pipe run and im going to be using Pushfit so throws thickness of ply out. 

Looking this morning I'm just about to buy this plate https://www.plumbarena.co.uk/product/abacus-easi-plan-universal-shower-valve-fitting-plate-epfp-05-3005/?gad_source=1&gad_campaignid=21120514031&gbraid=0AAAAADtJBDoeHhMCLjeUK4FC2lrF_Qksj&gclid=Cj0KCQiA6Y7KBhCkARIsAOxhqtP1ohFy0mOf-5zB5qx8SJeuu7FTAlUho74Upi9bA6eaf1QVWLH5lnMaAjeREALw_wcB

That means I won't be on Plyboard for the Pattress but im assuming very thin frame here. I can't find any dimensions on depth of this thing. 

Maybe better as an option ?

Looks like that would just get you where you can use push fit.

 

Remember that you need to buy a decent quality valve to bury in the wall as spares may be an issue later down the line.

 

If a client is undecided I just use these

But check prices of the face plate that you then need to go with it. For eg

This is a cross water valve, parts are likely to be available. 

I did stay in a hotel and did like the grohe value. This valve needs 80MM though so knackers me even more!

Ok 👍. I’d look at a spares kit ordered in now, o-rings / seals mostly, and possibly a spare thermostatic cartridge depending on £££. Should be 20yrs trouble-free motoring then regardless of what happens with the company / support downstream.

Crack on.

Update on this post @Nickfromwales, I think I am going to put the valve into the thermalite wall.
 

1. It means my arm wont get wet 

2. Wont be worrying about the 50mm stud conundrum and that being tight as a ducks butt, I've had the Abacus Mounting plate come in and that is going to take 10/15 mm.

 

I've decided to  got a pipe bender to run the 15mm down and up from the original water feeds in the loft. 

 

Pic has where I plan to run up pipe work.

 

I've got a 3 way crossbox backing valve and two way front plate, One thing im thinking about is running the 3rd outlet under the bath and blanking it off, it provides future owners with the option to change the front valve plate to three way and use the bath filler. Is that just me being OTT?

 

I know you mentioned you've used a Multi before, was that with a carbide tipped blade?

I've used a multi tool to cut Celcon before. Whatever blade, knife through butter etc. 

 

 

 

Wall chaser's another option.

Just cover all the pipes with a couple of turns of either duct tape or pvc electrical tape to stave off corrosion. You can then back fill the chases with dot & dab board adhesive etc or just foam them in, but best to cover the bare copper imho.

Not worth using plastic?
