    was going to take the 3" up to the elbow but couldn't get the long nipple. it's funny they got crimping solutions for bigger pipe but not threading. . .

    so i have skimmed a couple times but haven't run TSP first. compared to the old boiler and piping it has a much more stable water line but not perfectly steady. about 3/8 to 1/2" fluctuation while running. And you can actually track the fluctuations watching the steam guage. it varies about 1/8 or 1/4 of a PSI and then relieves. it is well equalized so i'm having a little trouble figuring what the water level would fluctuate with pressure like that but i haven't linked the phenomenon with high precision and maybe it isn;t the varying pressure that is causing the water level instability.

    It isn't carrying a lot of water, no knox, steam circulating to all rads within about 15 mins from cold start. couple are slower. i hadn't balanced the system before so I have a little work to do there.

    i was going to go with 3" all the way to the first elbow but couldn't get the 3" nipple i needed shipped in in time. I skimmed a couple times but haven't run TSP yet. the skim didn't look too bad. the water line has maybe a 3/8 or 1/2 is fluctuation running at about maybe a little over 1/2 PSI. and the pressure gauge is bouncing more or less in time with the fluctuation even though it is well equalized so I don't think that can represent bursts of steams facing pipe friction.

    I had always assumed that little surging behavior was more relective of the chaotic boiling environment. well its notably less than the old boiler pictured above was surging or unstable in water line. I think I though out the header a little better than the old one but awaiting your critiques.
