I want to add 2 litres of Sentinal X100 centrel heating inhibitor to my heating system. I have been removing each radiator as I have gone round the house decorating so the system will need some adding now.
If I buy 2x litre bottles whats the best way of getting it into a radiator in a sealed system (no filling tank in loft).
Is there an injection method for the bleed valve etc?
thanks
