Draining a hydronic loop to cap pipes
I am doing some demolition work in my kitchen. My heating contractor will be delayed in coming over to move the copper pipes feeding a radiator that will be removed for a new doorway.
I'm experienced sweating joints, so I would like to cap the two pipes to avoid holding up the carpenters, but I know that the pipes will need to not have fluid in them. Since the radiator in question is on the 1st floor and I have 2 stories, I can close off the loops for the 2nd floor. But do I have any alternative to draining the 1st floor loop? I am guessing that to refill it could be a pain with air bubbles.
