shut one rad off drain and remove the complete bleed fitting and insert chem.
or we do it through the pump, or filling loop.

I wondered about this especially when I was having a messy time trying to add some sentinal x400 to my sealed system. Then I saw the plumber do it when he fitted my new boiler. He had one of those pressurized bottles for spreading weedkiller and other stuff. He had modified the nozzle end with a fitting that screwed onto the filling loop. pumped up his bottle, opened the filling loop and inserted the inhibitor. Next time I have to add some chemicals, gonna make me one of those.
