Re: can I raise the wet return from floor?
OK. Step back a square or two here.
We have a critical question which, I think, has not been clearly answered.
Do we have a wet return serving only drips from a steam main? Such as might be found on a one pipe system?
Do we have a "dre return" which is, in fact, a continuation of a steam main back to a boiler?
Or do we have a true dry return up there somewhere, which would be found on a two pipe system?
The rules for connecting them to each other, venting them, and the elevations they run at aren't made up old timers rules. They are basic physics, and getting it wrong is one of the more common reasons why systems don't work well.
Re: New refrigerants Epa 608
What's the point?
When you've got equipment being engineered / manufactured poorly that dumps how many thousands of pounds? of refrigerant into the atmosphere per year, why does it matter? I've got a feeling it's thousands of pounds per month……….but I really don't know.
Now, some will argue the equipment leaks because it's made so thin to meet efficiency requirements. If that's the case, then those requirements are wrong and need to change.

was it ever enforced in the us other than for the most egregious industrial violations?

Re: Hartford Loop design origin
Does a plumbing p-trap limit flow? If the Hartford Loop limits flow, it's inconsequential and unintended.
