The radiator makes unbearable noises throu out the night, which drives her insane. We think that this is due to air pockets in the pipes, we can hear crackling and water drops.
The heating system is common to the whole building, and I cant turn off hot water.
How do i open this shit


I was living with roommates clueless about house maintenance stuff.
So one day I explain we should purge the radiators. Did I forget to say "purge the air"? I dont know. But the bucket I told em to use to catch water spilling one roommate thought was supposed to be used to empty the radiators. I was on the computer and saw him from the corner of my eye go empty his bucket a few times before I caught on.
