Radiator pipes into a wall

Kellez · 12 Oct 2014

Hello everyone,

I am renovating a house and i would like to hide one set of radiator pipes inside the wall. The radiator is at ground floor therefore pipes are coming down from the ceilling.

I want to use speedfit layflat 10mm pipes so as to keep the depth of wall chiseling to a minimum.

Can anyone guide me through this process? I know how to do this if the pipes are not inside the wall but i am unsure what to do when they have to be burried.

Its a brick wall with cement on top and a very thin layer of plaster.

I have already chased the wall but still needs some depth to it. However in order to decide how much more depth i need i have to know exactly what is going into the wall.

Thank you everyone

No special skills required.
Just create a chase in the brickwork capable of containing your pipework and clips. It's easiest to bring the pipes out behind the radiator about a foot above the floor in the centre of the radiator and use stem elbows on the valves.

Thanks for the advise, i have already chased the wall behind the radiator (centre) but I probably need a bit more depth.

Do you think i have to use a pipe conduit so as to protect the pipe (provide room) when expanding?

How exactly do you use the stem elbows?

No need for conduit if your using plastic pipes but it's a good idea to run a strip of foil tape or similar where the pipes are so that anyone in the future can trace the pipe work with a pipe tracer/stud finder.

And use this for a nice finish look

Great advise everyone, i am taking everything in concederation.... thank you

I am concerned about one thing, do you think i should avoid using any fittings (joints) within the wall?

do you think i could be able to bend the pipe at a 90 degree angle without any joints....i am using the speedfit layflat polybutylene???????

What do you think is the best option to connect speedfit pipes to radiator valves?

1) use stem elbows (i dont really know how this are used)
2) or just insert a copper olive on the speedfit pipe with a compression fitting and connect it directly to the radiator valve?

we have the speedfit pipe coming out of the wall (behind centre of radiator) and needs to be connected to the radiator valve.

so is this the corrected order?

speedfit pipe => stem elbow => radiator valve

stardanny · 15 Oct 2014

Yes, that is correct, for a better look.

Stem elbow is the same as street elbow. The pipe goes into female socket of elbow, the male stem of elbow goes into radiator valve with nut and olive.

Look at the Polyplumb online brochure.
