Just to rule out the H2S, can you go around a couple of rads, give them a bleed and give them a sniff?

No nasty smell when bleeding radiators.

So I have had the extractor vent covered for a few days and the smell is still there occasionally. Does condensate smell? My condensate pipe drains into an open drain that is shared with a water softener.
