Yes gents, it’s the microwave... Toilet actually goes into the original sewer line, if they had tried a longdrop I’d have gone right off!

Had another peek today, there is seemingly a worse error than I suspected. It looks like a good amount of the concrete footings are higher than the designated measurement for bottom of the concrete floor slab they’re supposed to be supporting. There’s only two solutions - raise the floors which means flatter pitch roof and an amendment to the approved structure - so a fortnight to three weeks down time, or rework the footings. I would do the latter with a couple of big fellows on jackhammers.

Fail at the first turn, get your hole in the ground right and everything goes better from there. They didn’t put in any plumbing penetrations either, that is another curiosity!
