Water out of steam valve....

Chuck_38 Member Posts: 3
I drained alot of excess water from my boiler, brought down water level in sight glass down to approximately 2 inches above loop, like instructed. Water still leaking from Steam Valve. Drained about 2 hours ago, could this just be left-over water in Radiator??? Will knocking and pinging also go away after a while???

    Steam Valve

    What do you mean by steam valve ? You mean radiator vent ? You can unscrew them and shake to drain . A better valve like a Hoffman would self drain
    I have enough experience to know , that I dont know it all

    The vent, yes. When heat/radiator is operational water flows out this vent. It's supposed to be a steam vent. I drained all the excess water out of the boiler like an HVAC tech. instructed me to do so, but it is still sending small amounts of water out of this vent. Don't know what else to do to stop this.
  • There's probably

    water backing up in the radiator or piping somehow. Is the radiator shutoff valve all the way open?
