Passable work or bodge job!?

[Keith O'KEEFFE]

Are you on a sealed system?? Also as the pipes heat and cool they expand and contract this is equally disturbing to the o rings as the pipes will move. Albeit fractionally but it still moves

AND taped up so any potential lime cannot pin hole the copper

Fabric tape will do, can also be used to hold up the wall.

So it’s a sealed system at a minimum of 1bar rising to 2-2.5 when hot. Up to you

You've lost me on that one I'm afraid! In my mind the chances of one of the O rings popping is relatively small. Just want him to get on with the rest of the job. We're in a Victorian property, it's amazing to me all the little bodges and quick fixes hidden under the floorboards, the ceilings and walls! You can get too stressed over every minute detail of a job and it just ends up with a Soded off workman

 

[Riley]

Ok up to you but your heating could conceivably rise pressure wise to 2.5 bar which is likely higher than your incoming mains. For the sake of two elbows I’d change it. And the minute details as you call them can often be the difference between a good and a bad job

You have to do what you think is best mate. We are only giving you recommendations on how we think that it should be done. But as long as you are happy.

Cheers, I'll be happy when it's all in and there are no leaks. Thanks again for the guidance.

Just bare that in mind if one of the John guest push fit fitting leak later on.

In my honest opinion, I wouldn’t be concealing a speedfit joint. The copper to the radiator needs to be protected from corrosion and movement (clipped).

The water regulations state the following:

No pipe shall be embedded in any wall or solid floor without meeting certain conditions.

No pipe shall be installed in a way it may become unduly warmed.

Since the original picture, the plastic feed coming into the room through the wall has been changed to copper and the Speedfit elbow dropping the pipe down is now soldered copper. It switches to plastic pipe once under the floor. The plastic joint on the right hand side of the radiator flow is now in the void between the joists. Only thing that will be buried now is soldered copper piping.

My opinion , 4o years experience.
1. Untidy pipes un supported
2. Yorkshire solder fittings .DIY in my book unless its in a tricky spot
3. If he wanted a job in my outfit..in the old days .he would
would have to improve
4. my boys would really have a go on a friday over a pint they are never backwards on coming fwds



5. However main test is will it leak it may not look pretty

Where does this myth of lime corroding copper come from?

 

[Welder]

"Copper water tubing has an outstanding history of corrosion resistance in most underground environments. Copper does not naturally corrode in most clays, chalks, loams, sands, and gravels. Certain aggressive soil conditions, however, can cause it to corrode. The basic prerequisite for corrosion is the presence of appreciable amounts of moisture. Other factors that can facilitate the corrosion process include soils having: (1) elevated concentrations of sulfate, chloride, ammonia compounds, or sulfide; (2) poor aeration, which supports anaerobic bacteria activity; (3) large amounts of organic or inorganic acid; and (4) large oxygen or neutral-salt (especially chloride) differentials."

In certain building materials, although lime is a constituent part, it may not be well mixed or indeed clumped. In these circumstances it can present as an acid to copper pipework.

I have always been under the impression that builder's lime is very caustic, i.e. alkali. In what circumstances does it become 'acidic'?

The only acidic lime I know is the evil green fruit...

 

[Aire]

That's strange because the same website recommends burying copper in lime chippings to act as a preservative.

There must be some reaction when the lime is mixed that makes it corrosive because natural lime isn't corrosive to copper at all, in fact copper artefacts have been found perfectly preserved in lime and they have been buried for hundreds of years.

I fully agree that copper should always be sleaved with felt at a minimum, but I've always done it on the basis it gives the copper an expansion gap and prolongs the life of the copper by reducing abrasion.

You're right, its acidity that corrodes copper, hence areas with very soft water can have problems with copper pipe.

Looks like the issue with copper through cement is galvanic corrosion due to soluble chlorides in the vicinity of steel (e.g. rebar)

Also acidity from a boiler condense can corrode copper 😱

Yep I found that out the hard way, didn't have any overflow pipe, used copper instead 😳 not my finest moment 😀

 

[Welder]

Personally, I feel all these formal tests simply fail to replicate the wonderfully infinite range of stupidity and lack of thought demonstrated by the human species. No matter what we look for, we can find evidence 'somewhere' for. Conversely, if we disagree we can find evidence 'somewhere' to back our arguments.

Perhaps all we can realistically do is to protect/do/carry on how 'we' see fit? It does make life extremely difficult when, like on here, we all wish to learn and improve but perhaps we just have to just get on a do what we believe in? Over time things will be proven and we'll all get 'better' at what we do. 😉

 

[king of pipes]

Poetically put Dave, truth is the workmanship is poor and can be improved on massively under no circumstances bury speedfit fittings in a wall the plastic supplies can be tidied up with little effort and if that's his best of effort of concealing pipes into a wall then your in trouble. Kop
