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


Why do you have to fix it?
Tell your GF to fix it.
Or are you the man of the house and you are supposed to know such things as a man?
Yes this was exctly THE reason…
But anyhoo, we found called a plumber. He said that screw is missing a cap, which makes it impossible to turn, no wonder i couldnt even budge it.
So it is not fixed, i am still alive, nothing has been flooded, and my GF calmed down. She can be rough sometimes…
