Buzzing noise

ariccio Member Posts: 4

I live in a 1960 multifamily high rise apartment building. We have a low pressure vacuum steam system. Of course, the building is way out of wack, and most of the steam traps haven't been replaced since I was little... I found a "learning to read" type of card when I made them change the trap in my room.

Now here's the weird issue. The steam trap in one room is making this loud buzzing noise! I made them change it, so it's a functional trap. It's coming directly from the trap too, I've checked with a mechanics stethoscope.

Listen here, since I can't upload an audio clip to the forum:

    Do you get heat ? If so let it go , in a multi high rise there are too many variables for you to correct ...

    There was an error rendering this rich post.

    I do. Lots of people don't. I wonder if the pressure is so high that it's causing this. Last time I was in the boiler room I saw it near 2 psi... Would that cause a steam trap to scream if it's designed for low pressure steam vacuum?
