So on 2 different van/TMs my guys are having issues with water not flowing to the wands. By process of elimination we find and remove the hose that has no water pressure. -but oddly the problem will move to a different hose. And the hose that was removed will begin working again or later in the day.
Do QC (internal springs) stop working at certain min or max psi? Does excessive heat make them fail?
Tech thinks it's the water pump, which I doubt.
I don't run chemicals through the heat exchanger and I descaled them last year-- could it be the HE.
