Fixed end of last week, seems to be holding pressure fine

If you can't see it from your property why do you want to remove it?

We had a 170m2 200mm slab put down and powerfloated with a graphite coloured dry shake on the top, came in at about 4k ex-vat IIRC.

The plumbers were meant to be repairing this, and they were the ones who actually connected the loops to the mannifold and commissioned it all before screeding, so they should have been well aware of all the pipes. Just seems like this information didn't filter down to the genius with the lump hammer

@Joe90 do you want to tell me how good your builder was again? 😄 I think that would finish me off...

Alright alright, come on I need some positives here!

Because I had 24 pipes coming through a doorway and going up a corridor

So a skilled tradesman turned up in site yesterday to expose the damaged ufh pipe ready for the plumber - and promptly put a hole through another pipe. You honestly couldn't make it up

Well I guess the composite sheets form a vapour barrier too, so guess so

yep, but BC insisted we use a vapour barrier to be sure

Our roof is corrugated steel sheets over 150mm thick PIR/composite panels and the rain was quite loud. We've now finished the internal pitched ceiling with 200mm thick rockwool (just standard stuff, not acoustic) behind PB and can't hear anything anymore. Just the slight echo of my empty bank account.

If you've got an UFH mat then solid wood might not be best, engineered better

Didn't pursue any further tbh, opted for the usual ASHP and UVC in the end, hopefully being fitted end of March - better late than never!

Heard back from the plumber and he would prefer to use a press-fit coupler rather than the standard compression. I said I was happy to go with whatever he recommended but any reason not to use a press-fit here? He said more reliable...

Only one pipe is damaged - the other two white marks are where I painted around the pipe in white emulsion to highlight it. That and marking where the pipe was on a floor plan and telling them to not to effing go near it I thought would have been sufficient, clearly not!

Yep

Is there some sort of resin that could be poured around the fittings, a bit like the stuff used in the connections used by power companies to join uncerground cables?

Not possible without major work, there is about 100m in total and would be a complete nightmare.

That'll be me! Almost 2km of pipe laid and that was the only bit that popped to the top. Should have been seen and sorted by the people who poured the anhydrite screed though.

Thanks both. The floor people have accepted liability (how generous!) although not actually apologised. They are paying for the plumber to dig out that section of pipe and replace. However I will now be left with two compression fittings buried under the floor. Honestly, the level of incompetence displayed by some people is astounding and is a never ending source of wonder and amazement to me.

So inspite of making people abundantly aware of this exposed UFH pipe in my screed they have still managed to go over it with the floor grinder. The outer PEX layer has been taken away in a few places and the inner alu layer scratched. No holes fortunately and the system is still pressurised. There is a few mm of latex screed going down next, then an engineered wood floor. Should I leave alone or get it cut out and replaced? I'm worried that cutting it out will cause more issues and then there are two compression fittings to leak in future. Thoughts?

Thanks for the input folks. I've had to park the idea for now as the tilers have managed to cock up the cut out around the shower controls so need to sort that one first. 120x120 tiles are going to have to be hacked of the walls and redone. FFS. Does any trade, EVER, not cock it up? @nod @Nickfromwales et al. excepted of course....

Hi all - the tilers are in and no one seems to have thought about access panels, they'd happily tile all the boxing in and leave all the tap tails, cistern feed etc inaccesable when the inevitable happens in the future. They have suggested some tile magnets to hold a tile in place over an access hole cut in the tile backer, but these just seem a bit flimsy to me ( https://www.tileexperience.co.uk/schluter-rema-magnets-set-of-4 )- I can just see the tile coming out and smashing. There also seem to be tileable access doors out there eg https://hidex.co.uk/product/tile-access-panel/?gad_source=1&gclid=Cj0KCQiA5rGuBhCnARIsAN11vgSoBLQb5k0FhQZCjExM8FNxxlVGr8fO2PXCEnC9uu-MKE-dhaam7QQaAuKKEALw_wcB . Any real-world experience of either of these things? Cheers all

I think you all need to meet on site to sort it out - the boss man, his surveyor, your builder and you. Going backwards and forwards over email clearly isn't going to go anywhere and sometimes you just need to do these things in person. If they refuse then at least that's an additional point in your favour if it does go to law.

Their argument hinges on this, if you can prove that the opening was not made smaller when the bow was sorted then they would have to concede that the surveyor was wrong. If you "signed off" on the meaurements by eail then it might get a bit tricky, but at the end of the day you have to trust the surveyors measurements, because what's the point of having one anyway?
