Was fine all season, then...!

Have two 28 section column rads fed from a common 2" branch which splits into two 1-1/4" risers. The rads are above each other (1str floor, 2nd floor). At the start of the season both were heating nicely, both had Vari-valves on them set about 25%.

All sunlight and roses until Oma, being frugal, shut the valve on the rad on the first floor last week.
That rad filled with condensate and was spitting LOTS of water when the valve was next opened.

The weird part is, after I majorly repitched the 1st floor rad and put a Maid-o-mist 5 on it, the same thing started on the 2nd floor rad the next day.

What gives?

Did the same on the 2nd floor rad (repitch, smaller vent) and it seems to have solved it, (for NOW) but I don't like mysteries.

    If you radically repitch one of two radiators connected together, it is possible that the pipe connecting them was forced to move the other one.

    Why did you majorly repitch the first floor radiator instead of just opening the valve back up?

    Nope, moving one didn't move the other (there's a swing joint and 20' of riser).
    I repitched the first one because it wouldn't stop spitting. Same with the other. Weird.
