Ok. its a pipe that stems from where the return lines meet (close to the boiler, a little above floor level). It rises from there and then goes to another part of the Building to heat other radiators. Well this pipe has a little valve(mushroom looking thing, is it even a vent?) on top of it (on its way up from the return lines). Its actually by the elbow where then the pipe goes on to heat other radiators on 1st and 2nd floor. What type of Vent should I use??? Also is this mushroom thing supposed to spit bits of water?????

    Can you post a picture of this?
  • spitting valve

    spitting vents can be caused by:
    1.bad vent,damaged by water-hammer on tee above return drip.test by replacement, and piping correction.
    2.pressure in excess of 16 oz.
    3.dirty water causing wet steam.
    4.incorrect steam piping causing wet steam.
    there is no magic bullet for these just check and correct those, and you should be good to go!--nbc
