    Magnacleanse connection via Fernox TF1

    Thanks Rich, is there another way of connecting it without one of those (i.e. elbows, hoses, reducers) as they are about £65 Adey state they can work alone without a powerflush, simply closing of each rad in turn & using the VibraClean, have watched a few vids doing this without a powerflush

    Cheers, what cleaner would you recommend X300 x400 or x800 or just drain & flush with clean water? Would a Grundfos UPS2 15-50/60 130 or the Grundfos Alpha 2L 15-60 be the one to go for? Many thanks again for your advise
