Go on! Be brave! :smile:
Honestly, - on some houses removing rads method is quicker than proper power flush I bet. Certainly no slower from what I see. I also reckon if after some power flushing is done and a rad is removed, there will be crud still in it.
Bugger that.. I imagine black sludge spurting out over walls & carpets 🙁 plus it gives me a bad back just thinking about the concept!!
