Had to replace / clean cold feed pipework due to a build up of magnetite from header tank through 15mm to 22mm tee.
So, looking at giving the system 4-6 weeks of X400 before flushing then adding X100. However, I’m in a bungalow with all the pipework under a subfloor feeding five rads (except the boiler feed / return, and cold feed which are in the loft).
I’m assuming to clean the under-floor pipework which sits lower than the rads, I will need some form of pressure cleaner, or will the X400 eventually be pumped through. Also, how will the x400 clean the rest of the cold feed pipework?
