I need to bleed my baseboard heat system because my super is taking forever to come and do it. I know how to do it, but my question is... How much hose should you take out of it?
How do I fix a leaky knob??
Answers:    You are not trying to filch water you are trying to hold air if you are getting adjectives water next stop and move to the next radiator. so in answer to your interview very little hose down.
Good luck

When you are bleeding the system, you are only looking to remove the atmosphere. When the water comes out, stop. You also must sort sure that the heat is on at the time you are bleeding so that it is pumping through the system when you bleed, or you will suck nouns into the system.
