in THE MAIN WALL
2 years ago i did a single drop header , some techs say i should of done as double, the system is working fine, the question is, is a single drop header better then no drop header? I also looked at union steam sight and they had a water separator has anyone ever used them?

    You’ve asked these questions before @Snowmelt, just do what you want to do. Since you’re asking again though, We’ve progressed over the years from header to drop header, single riser to multiple risers, 2” to 3”, etc. Now we always use all riser tappings into a drop header, never bush them down, and 3” is the smallest header size we will pipe. It’s become our routine and isn’t much harder or expensive. If done this way, it’s the best product out there and that’s what we like to offer.

    ive used single drop headers many times and they work fine, but its the btus and manufacture instructions that determine this, if you have over a certain btu then i would definetly use two risers and especially if the manufacture recommends it!!!!!!!!!

    Thanks newagedawn, all I see on here are double drop headers, my supply house who looks at this sight says it’s overkill sometimes. Now saying that I did a drop header one time on a repipe because the third floor rad.”furthest rad in the house” did not get any steam I did a drop header and WHAM steam made it to the rad.

    The manufacturers minimum requirements will work if the boiler is skimmed. If you want to add more risers, bigger header or a drop header your free to do so and spend additional $. Many on this forum do just that.

    I usually calculate the velocity just for fun. If I don't like the mfg minimum piping I will change something to get what I know will work

    i always used a 3" header, even with one riser, costs more but the result is worth it, a trouble free steamer
