When I prime the solution line for the first job of the day on my 870, I’ll see clear water followed by white and then black and then back to clear. What the black coming from, is it a warning sign?
Black in solution line

Black in my lines has either been from the interior of my pressure hose starting to deteriorate from age and chem abuse, or from scale buildup inside my machine. If you have a newer unused/ less used hose, it could tell you if the water is coming from the machine or the hose.
Search black death in the search bar here. Your hose could be getting ready to blow.
