Hi,
I want to add inhibitor into towel radiator for the heating system. I saw from Youtube that people normally open the radiator vent plug from bottom, either left or right (photo 4 and 5). But I saw someone opened from top which looks easier.
Please see the attached photos 2 and 3, should I just use wrench to turn the radiator vent plug? There's a small part in the centre of the vent plug, this seems is to use screw driver?---I don't think I need to use screw driver to do anything with that, do I ?
Once I open it, then put a hose into it, and inhale it quickly so the radiator water will come out till all out, then I can add inhibitor, is this right?
Thanks!
