Thanks to all,
I bought Fernox Super concentrate, all I had to do was turn of the
valves on the radiator, remove the bleed screw, insert the adapter,
open wheel valve, pump in the inhibitor, close the wheel valve and
close the vent screw. Re open valves to original positions.
Very easy and quick, the inhibitor comes in a silicon type tube and
you use a silicon gun for pumping it in, the product comes with all
adapters.
Although it may sound tedious, it wasn't bad at all.
Sounds a good product - but not sure how you managed to inject a
quality of anything into a full radiator with the valves off - so
there was nowhere for the displaced liquid to go.
Perhaps there was some air space.
I was surprised, the instructions mentioned nothing about draining,
you do have to replace the bleed cap quickly though, to prevent it
spitting back out.
I tried that method & wondered how you were supposed to get any product in
without draining any water out. It did work after a fashion, but the
pressure on the tube was so high, product started leaking back past the
internal plunger. I had to crack open a joint to let some water out in the
end.
