Recently I added a few rads to my OFCH system and 2 rads don't get hot.
I have been letting air out of one of the cold rads, hooking up a plastic tube to the bleed nipple and placing the end in a bucket of water, so I can clearly see the air bubbles.
I have already drawn off a few buckets of water and the bubbles just continue the same.
I turned off most of the rads on that line and then the rad I'm bleeding gets hot, but the air bubbles persist.
I'm wondering if there is any point in continuing to bleed the air, since the bubbles just seem to continue...?
