today is the important day of the year where i bleed the radiators. like a medieval physician employed at the court of the boiler. i have a wadded rag of fabric and this special brass implement which i twist. i have to ensure the 4 humors of the central heating system are in balance: clear water, rusty water, methane, and some kind of fluming effluvium. i think the rusty water represents blood, but don't take my word for it, i'm not an expert. speak to a bearer of the crest of the hound of wales
@jk I switched to radiator leeches ages ago. It's a far more enlightened approach.
