Hi everyone. Want to start cleaning my flue pipe/chimney myself and need some help with where to disconnect to do so. The people I’ve hired to clean use the flexible rods and go from the bottom up without disconnecting but I am thinking of disconnecting the interior to do a thorough cleaning of all sections without the extensions and bends. Before I dive into this, do I simply unscrew the very top and very bottom set of screws and slide down the pipe and pull out in a single piece for cleaning? Any thoughts and suggestions are greatly appreciated.
