Long story short: I am a superintendent of a luxury co op in NYC. I oversee all day to day operations and renovations in ppls apts. Few rules to really go by buy for some reason they can't seem to follow. When installing branch valves you must braze t.p. to copper fitting. Guys come w small map gas tanks trying to braze. It's crazy. Plumbers installing toilet offset so bad that there's going to be problems later on. And the General Contractor just wants to take $ and run. Wish the building would allow me to do the work!! Sorry rant for day. Below is picture of toilet offset 2" and you can see the bend is going to be a problem.
