I've made a few changes to my central heating system, namely changed a rad, and its pipes. The system has been partly drained a few times over the 5 years since the combi boiler was changed so I thought I would add some inhibitor, sentinal X100.
I left my new rad isolated for this reason. I opened one of the blanks on the top and inserted a length of pipe into which I poured the inhibitor. Instead of going into the rad, it just ran out again. Poking my finger inside told me that the hole into the rad is half way up ball shape inside, so by the time it reaches this, it has already run out of where it came from.
Am I doing something wrong? How do the professionals do it?
