Powerflushed a system today for a new combi to go in, coming out was an old open vented pumped central heating system with a multipoint for the hot water - no cylinder.
I've done about 6 powerflushes previously until crystal clear, using an anton powerflush machine connected to the flow and return pipes from removing the kitchen radiator.
Always been treated previously with cleanser, F3 or X400 for up to a week before. usually the pipes flushed on their own then the radiators one by one.
Today we got out a fair amount of dirt but nothing substantial from the pipes and each radiator using the powerflush until the water ran clear and also regulary reversed the flow. It was only when changing a radiator valve afterwards we noticed the water was still thick black, worse than anything that had come out of the powerflush. We took the radiators off and flushed them outside with a hose pipe, tilting them a few times until they ran clear. Completely black like they hadn't been flushed at all, couldn't believe how bad they were.
Now I do think that powerflushing must still be the best practice for flushing the pipes but surely the only way to get it all out is to remove the radiators and manually flush outside? Anybody do this? In future I will be inclined to do it with almost all radiators that need thoroughly cleaning.
Or how about one of those fancy power flush filters? We have now fitted a magnaclean to this system and will be going back in a week to check it out.
