What is microbore:


Measure the pipes terminating into your radiators. Whereas 15mm pipe is about the thickness of an AA battery, microbore is more the thickness of an AAA battery or thinner. Microbore comes 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.
