Main line steam vent
Not sure if this falls in the bandwidth of this forum, but I thought I’d ask the experts just in case!
I have a single-pipe steam system in my 3-story home. In the garage, there is a main line steam vent right before the pipe goes into the garage ceiling and is no longer accessible. When we got the home 2 years ago, the contractor replaced this valve to help get the radiators steam at the same time.
today I was poking around in there as the heat was on and held my hand above this valve. I felt really hot hair blowing up on to my hand. It wasn’t hissing or gurgling, but I definitely felt heat that I’d assume should be staying in the pipes. Based on some initial reading, I guess it’s possible that the vent needs to be replaced, or that the pressure in the system is too high for it.
