If your heating system utilizes microbore piping, watch for these "red flag" symptoms: Microbore pipes, typically 8mm or 10mm in diameter,

If a pipe is completely "capped" with hardened magnetite, chemical and mechanical methods often fail.

Dealing with blocked microbore pipes (typically 8mm or 10mm copper) is notoriously difficult. Unlike standard 15mm or 22mm pipes, you cannot use standard drain rods, and they are very susceptible to blockages from sludge, hard water scale, or improper system flushing.

If the "long piece" is completely solid with black sludge or hard limescale, cleaning it is often temporary or impossible. Because the bore is so small (8mm/10mm), once the internal diameter is restricted by even 2mm, the flow is ruined.
