Hello,
Ive had a new boiler installed around 10months ago. All works fine. I decided to clean tf1 filter and there was quite a lot of black tar substance.
I decided to flush tf1 with some water from return and the water is totally black.
I didnt have powerflush done as the water was clean when the new boiler was installed, but i remember the installer cleaning the system using a pump or something similar.
I think the have disturbed sludge in rads and left it there.
Whats the best way forward.
Should i add x400 run it for a week, drain the system and add x100?
Cheers
