Not sure what the white buildup is in my drain line coiled up under my drive bays. Obviously there is no flow through it since its a dead end. Should I be concerned? I was going to wait until spring to drain and do a cleaning but now I'm not sure. Been running Mayhems pastel berry blue for 12 months with no temp issues. The pic doesn't do it justice, half of the line has a milky white color to it.
The residue is ONLY in (or noticeable) the drain line. The rest of the loop still looks very berry blue, like some smurf ****e.
