I live on the 14th floor of a 30 story apartment building and so far, I’ve been bleeding my radiators myself.
This usually worked and after bleeding I had a fully functioning radiator, 100% filled with water.
However, last time I tried bleeding, it would only fill up to 25% of its volume, it’s like there’s no pressure in the circuit.
Am I doing something wrong?
Having lived in a house with radiators, bleeding registers is like a once every 5 years type of task. There’s a much larger leak in the system, you should talk to your apartment manager.
