So Im sweating on one of my Taco isolation flanges. The valve was open and the 4' piece of copper was open at the other end. As I looked into the opening of the flange to see what my solder joint looked like on the inside, I grabbed the handle of the valve to see if it was operational. I gave it a slight turn and promptly got blasted in the face by hot steam. It seems that pressure built up between the ball and the housing from the sweating. I was shocked by how much came out. No damage done, but certainly can add it to the ever growing list of lessons learned on this project.
Also, can I leak test my system by pumping air into the system (assuming I isolate my air eliminator and expansion tank)? I would assume air would show leaks better than if I filled it with water. It would also be easier to go back and fix leaks without having to drain the system.
Thanks for any input and Happy New Year.
