What is microbore:

.
Microbore is pipework that is under 15mm thick by the radiator valves. They come in many sizes but 12mm, 10mm and 8mm are the most common. When these systems sludge up, working on them is harder and takes much more time than standard systems. Standard power flushing on these systems is not recommended as they often fail to fix the flow problems.
