Is it air or hydrogen, when bleeding a rad?

[learnplum]

Hi all, how do you test for hydrogen, when bleeding rads?
If I know the gas coming out of the rad is hydrogen for arguements sake when I bleed it, then I know internal corrosion, is taken place.
So I can eliminate, air being sucked in.
Thanks:tounge_smile:

Put a flame to it

As above. And if corrosion is taking place, air is being sucked in.

If it is hydrogen. Turn off at gas meter and re-pipe system. Ha Ha

Grab yourself a T3 meter and that will tell you mate.

I hold a cup, upside down over the vent when I bleed. Shut the vent and insert a lighted match into the cup. If it goes pop it's hydrogen.

OK, thanks, I think I get it.
