I drained a rad into a demijohn at the weekend, someone's already commented on how good my home-brew looks! It's the colour of black tea, but not cloudy at all. Is this correct? Or should it be clearer?
A few small hard black lumps also came out. I replaced all but two of the rads 18 months ago, the system wasn't flushed but was drained down completely. Quality (Sentinel X100) inhibitor added. Should I run some X400 through it?
Thanks P
