    Looks good, but I do see one issue. The Hartford loop is supposed to utilize a close nipple to make the connection as short as possible. You have a tee in there.

    Otherwise it looks good to me.

    I'm trying not to be overly critical here, especially since you may not do this for a living.

    Near the top of your photo it appears the new piping is three inch that feeds the steam main. It looks like you used a three by two inch concentric coupling to reduce the size (this will cause a dam) and then you fed the existing (painted red or brown) and used a what looks like a two and a half by two inch bushing. I realize that not every supply house carries every fitting known to man, but I think you may have some issues with the dam and the slightly undersized pipe (two inch section).

    Can you see how steam/condensate would want to lay in that roughly 3" x 6" horizontal nipple that reduces down inside that coupling? Can you see how the 2" pipe that comes out of that same coupling may not provide the same flow as the dead men calculated for the roughly 100 year old 2.5" piping (painted) that feeds your two 2" steam mains?

    To be honest, it may work fine and not hammer or provide wet steam. Everything certainly look plumb and straight. I am not trying to pick on your work, despite the fact that I've been in the heating business for over thirty years, our work is not always perfect either.

    If that section is pitched down, there's going to be a permanent puddle next to that reducer. I'd expect a bang or two at the start of every cycle. When a steam cloud hits cold water, it collapses pretty violently.

    I’m nobody but I’d bet no water is going to pool there.

    But yeah I’d rather see the riser be 2” or whatever size the main is

    Won't be a problem as long as it pitches back toward the header.

    Sorry for the delay guys, yes that is a reducer bushing to the original steam main and the reason I left it there is because I couldnt get it out, it was connected to a nipple, and then an elbow, which I was able to cut and get the elbow off. It does have a slight pitch return and it doesnt bang. As a matter of fact, I was pleased as punch that there is no banging at all. My last residence (apartment) was banging all the time,.

    Since we've started the heating season, one more question, right now Ive got my thermostat (wifi-smart) swing set at 0.50 so with the system set at 70 degrees, its running on tight intervals..I dont know if thats correct or if it should be longer. Thanks!!!!

    Any water in that 3 x 2 reducer will drop down into the boiler

    Yes, like I said above, I havent had any trouble with it so far, the only trouble was with the vents on the radiators, they were crap, replaced them with crap, then threw out the crap and got hoffman vents, there are no vents on the mains at all... :(
