I'm looking to flush my central heating system as some time back, i noticed sludge/almost iron fillings in my Fernox TF1 which i assume is due to lack of inhibitor
So i know i could hire a powerflusher (quite expensive) which i believe you fit in place of the TF1 temporarily, but could i achieve the same by taking a feed from my cold mains with a double check valve to prevent any back flow and contamination, and then flush the system that way with the outlet going into the drain ?
Once the outlet runs clean, i could then add the Fernox inhibitor via a top radiator and then bleed/top up as required
Does a powerflusher need the boiler running for a period of time while it does its thing ?
Is there any reason why i wouldn't want to clean the system this way or why i shouldn't ?
To me, its the equivalent of taking all the radiators into the garden and flushing them with a hose !
My boiler is a Worcester Greenstar 37cdi btw
