High low always

If there’s no air stop bleeding it’s not an air problem. This is a scary post for me but I have to say sometimes it is. I’ve never seen this with an original dead men system but the trouble happens when they get modified (usually by PEX pirates) to move a radiator here or there. The riser will end up with peaks and valleys and air just won’t exit (without a little extra help) I take an 1/8 x 1/2 coupling and screw a draw off into the bleeder opening. Hang a double ended hose out the window and let it rip. Drop the pressure in that radiator as much as you can. As we all know - high to low always. Both risers will start feeding and there goes the slug. Have a nice weekend guys
