Day In The Life of a Plumber, Micro Bore Powerflush & New boiler Installation

Powerflush Microbore system. A brief video of how to flush a system before installation of a new boiler as per Benchmark. This system had 5 rads and a very large Gloworm eco combi energy saver installed that was 20 years old. We condemned it due to several issues and various parts that very not available anymore. Ironically the Prv was leaking due to the usual None servicing of the boiler issues, however even on re pressurising of the expansion vessel it still held up after all those years ! The filling loop was left open so constant trickle of water into the system occurred. What you see is 20 years of muck on a typical "sealed system combi" I will be stripping down the combi in a later video to show the guts of it if anyone is interested comment below.
