I hope someone can answer a question for me, I had a new combi boiler installation today, straight swap for the old one, the guy did a flush of the system using fernox 3 then added fernox f1. This is all from the info I have taken from the installation log. My question is he did it all in 3hrs, is it possible to do a system flush and install in this time? I am not a plumber or Rgi but I would have thought a flush would have taken alot longer alone
Thanks for any replys
