Please help! I've been sleeping on the couch for two weeks (I'm 25 weeks pregnant) because ever since the heat was turned on in our building, I can't sleep through the clanging noise in the radiator. The plumber came yesterday and let steam out of the traps but that didn't work. I am at my wits end. Seriously thinking about giving up an amazing apartment over this (I get it through my employer). Does anyone have any tips I could pass along to the building manager?
