An old timer showed me this trick after I changed a circulating pump and got air in the system with no bleeders and I tried for hours to get the air out, he came by and within 10 minutes he had it fixed, needless to say I felt like a dummy but il never forget it and have used it many times now. Hope this helps.
Thanks, I actually thought of this on my own while I was there, believe it or not. I don't think it made the process faster but it made it easier to see when the bubbles have gone.
