Hi guys
I have drained down my system, done some pipework, and installed a new radiator. When filling and flushing the system for a 2nd time, I noticed sludge in the new radiator. I am thinking of adding sentinel x400, fill up and leave it for a few weeks and then flush it. My question is does the x400 act as an inhibitor? or must I add the x100 too ?
