2 pipe steam

Just looked at an apartment building where a few of the radiators had the valve (inlet) up high and the trap down low on the same side of the rad. I’m not sure I’ve ever seen this before? From what I’m told, they work and I don’t see why they wouldn’t? Is this common? Wrong?

    No reason why it won't work, @Stephen Minnich -- I have half a dozen of those in one of the places I care for, and they seem to work just fine.

    Typical Vapor setup. The steam enters at the top and displaces the air downward. When it gets to the bottom it doesn't matter which side the trap is on.

    yes, fine..the rule if i remember right, was as long as it wasn't three times its height in length it would work fine. If memory serves that was the OE vapor rule.
