Burying copper pipes

[strummerman]

as dave about his copper pipes :lol:

closure plate tape from a plumbers merchant is perfect for the job don't worry too much about thermal expansion done loads never had a problem, virgin copper is available but carries a premium price tag usually reserved for special bath tubs (healing properties)etc most of the copper we buy from merchants is recycled mixed with alloys. the different thickness's or guages are for use outside or inside (outside being thicker) although most now use poly.:smilewinkgrin:

There is also plumbers felt wrapping you could use if your that worried about expansion.

It comes in a flat roll you wrap around the pipe in a spiral, or there is also a sleeve variety where you just slide the tube inside it.

Personally, I would just do it with duck tape or similar.

Copper is getting thinner and is also a mix of metals today, I think there are 3 different grades of copper M,L & K? all of varying thickness... I have noticed since the price of copper went through the roof copper is getting thinner... this is why it's sometimres hard to guage price from one supplier to another

CR, yes those are the grades we have...whenever possible, we use L copper. I have been told they use K copper in areas where well water is aggresive on the pipes.

depends on the layout but if you can solder on bench then give em coat of hammerite paint, let em dry overnite and then tape em, ive an old mate whos done that for as long as hamerites been arouns with no probs.
Belts and braces you could wrap em in fiberglass kit, maybe little expensive tho! :lol:

I'd chase them in, make sure they're clipped back and cover with duct/insulation tape. White spf for your trav and away you go!

 

[cornish_crofter]

Pretty much as Doug says really, use SPF as opposed to mortar/render.

However, for floors I use Denzo tape over the top and lay the pipes on some damp proof course wide enough to span the number of pipes. For a couple of pipes next to each other 4 inch should be enough, then the denzo tape will adhere to the pipes and the damp proof course. Then apply the spf over that.

As Cornish, Denzo tape for me.

I use duct tape, fix the pipe back with 16mm clips and then foam the pipe in the wall. This insulates and allows for any movement in the pipe.
You do not want to mortar the pipes in as this over time corrodes the pipe and also can lead to joints cracking as there is no room for pipe movement.
Where the pipe passes through the tile, I diamond core through using a 365 bit and cap the pipe with a chrome rose.
Looks sweet:smilewinkgrin:

Thanks all for the tips!

The walls are chased. I am having a hard time finding enough space to put pipe clips in though!

Also, should I be concerned by the 3 or 4 90 deg elbows behind the tiles in the wall - should there be any solder joints at all or am I asking for trouble?

A tad worried about this one, especially as its in the outside wall (OK its 2ft thick) - but if it leaks :yikes:
