Destined For Failure?

in THE MAIN WALL

Is this a leak looking for a place to happen? Boiler feed line into equalizer line.

    Nothing wrong with Pro Press. 

    Now is it the proper fitting for that application?

    That would probably be the better question.

    According to Viega, MegaPress is approved for steam. Not sure I would use it though. Threaded fittings allow for movement.

    It's not propress it's Mega Press.

    You can have it done good or you can have it done fast.

    What pressure is the steam? 15 psi or less it will probably last a while. Now they have Mega up to 4"

    We have just had a new Weil-McLane 88 installed and the installation contractor, when finished, had us at 8 PSI. 
    I had a steam consultant in after the installation and he said it was way too high and adjusted down to 1.5 PSI.

    If it was set at 8 psi, I’d love to see what the near boiler piping looks like.

    Our first problem was the boiler feed line was installed above the water line... sounded like the battle of the bulge. You should quickly see problem number 2!

    I see problem number 2 which is the near boiler piping is all incorrect and needs to be redone.

    Can you educate me as to why/where the near piping is wrong? I'm a 30 year warm air guy starting to learn boilers.

    Risers not high enough off the boiler surface?

    Welded risers with no swing joints to allow for expansion, takeoffs between risers, press fittings on steam are still rather experimental (IMHO, others may not agree), can't really tell what the pipe sticking down over the boiler is but it seems to have a shark bite cap on it.

    As @ratio has said there is no swing joints and the boiler riser take offs need to before the steam main take offs.

    Thanks everyone for their help! Does the threaded 4” pipe riser coming directly off the boiler count as the swing joint? The riser is threaded at the boiler take off and the bottom of the flange.

    I love page 17 lol... 
    interestingly, We have a 688. Fig. 24, says riser A should be 5” but specifies a (1 riser) Whereas Fig. 25 shows models 788-1188, with Double risers but at 4”” to 5”
    we currently have 4” risers. Seems a bit confusing there. Semantics?
