sinking copper pipes in wall

[blackbat]

What are some suitable materials for covering copper 15mm pipes that I want to sink into a wall and plaster over?

Bearing in mind the plumbers merchants are now closed for the weekend.

Would electrical insulating tape do the trick? Obviously not too heat resistant.

Depends on the run, but I ran my ones to the shower inside 20mm plastic electrical conduit. To bend this combination, I used a

22mm pipe bender. You might also be able to do it with a 15mm internal spring bender if you don't have a proper pipe bender.

Thanks - I guess I should allow for expansion too. Your solution does! I wonder whether pipe foam lagging would also be suitable...

Whatever you use won't be heat resistant, a lot of plumbers use duck tape, it's only to protect the copper from the cement....to minimise cracking afterwards, cover with fibreglass or foam rubber prior to plastering - this gives a mm or two for expansion.

Oh its fine.

But BULKY.

Expansion you must allow for.

I've even used bits of expanded poly cut from whatever to cover up pipes before slapping the wet stuff over the lot. join it with PVC packing or Duct tape.

If its a wall you need to address minute amounts of expansion, and almost any nonrigid cover would do that, even rag & cling film, anything that'll survive being plastered over.

Denso wrap

Available from (larger?) Q&B, but you've got 90mins to get there ...

but 2 hours queuing :-(

I've just trimmed some foam lagging down to half its thickness with a sharp stanley knife - it may do the job.
