I have recently repaired some radiant heat runs. I watched a video of you draining air from a boiler.
You had your boiler running while purging air from system. My set up for my boiler is almost identical to the one you demonstrated. while my boiler is running, there is no water or air coming from the hose. Only when the boiler is in the off position can I get water to purge from the hose. The good news is that I am able to get a lot of air out of system.
Why is this?
