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
Talk to your GF about mutual respect in your relationship.
Or botch the heating, then give her an afternoon to clean up the water damage.
