Time's Ran Out
I'am just a tiler - never been on a 2 day course for anything so what would I know!
I think that although the way it has been done is not 100% to spec that it would be fine, not that i would ever question what Schulter recommends but i also (same as Widler) can't see what the problem is with how it's been done. If you had been able to get your hands on it from the off then i would have certainly done it the way Schulter suggests but you gave your advice and you was ignored and they chose someone else who would do it there way so i would just leave it there mate, your conscience is clear that you advised the 'correct' installation for that situation....
Builders always no best anyway!!!!
In 2 cases I have come across, architects always no best too ...!
