so of course we were a bit annoyed, but mainly because of the lousy excuses from the plumber saying it was normal and so on... only after I was able to prove directly to the construction company with the planning documents that there really was a problem, they now want to do something. the plan was a ring line, so it would have been easy to integrate the circulation (no idea why they didn’t do it that way from the start...). they simply skipped a section of pipe, which now has to be installed.
the house is of course still habitable. it’s not like they’re tearing up the entire hallway. I think it will be about 4-5 tiles (across the normal walking direction), so you can even step over the hole. and after work a board will be put over it. it won’t take long anyway. with properly coordinated trades it should be done in 2-3 days.
during the on-site appointment we will still discuss whether it might be possible to go back from the pre-wall installation in the guest bathroom to the utility room. then only one wall tile in the guest bathroom would have to be removed and the screed would remain intact. just one core drill through the wall. in the end the pre-wall just has to be restored +1 tile and done.
attached is a picture of how the plumber admitted to having installed it. thick line larger pipe diameter, thin line I think 12x1 pipe. if I’m not mistaken they should all be copper pipes.
