Blocked Microbore Pipes [hot] Guide

: Install a filter (e.g., Adey MagnaClean) on the return pipe to catch sludge before it enters the small tubes.

Because microbore copper is malleable, it is easily kinked during installation or DIY work, creating a permanent restriction where debris can collect. Key Symptoms to Watch For

: Good for light sludge but rarely clears a solid, total blockage in 8mm pipes. 2. Manual Rodding and Wire

: Using a specialized tool like a "Kinetic Water Ram" to send a shockwave of air through the pipe.

Blocked microbore pipework is a common failure mode in aging heating systems. While power flushing may offer temporary relief, the narrow bore and accumulated debris often necessitate partial repiping. Replace the most severely affected circuit(s) with 15mm copper or plastic pipe to restore reliable flow.
