Hi guys just a quick question.
I have always used the doc fitted at the lowest radiator in the c.h. system to drain down the system. What is the doc in the boiler for? If i used that one i would certainly not be able to drain the whole system down as it is located above the radiators level!!!! Thank u in advance 4 the clarification.
