I think of the crud as 'fall out' but in reality I think it is minerals that get excised from the water by the heating element and how hot it gets. It's the same as the crud that develops in your home water heater. You are suppose to drain your water heater at home yearly to get rid of this stuff.

NOTE: Just read up on several other RV forums and "Crud" is the official name for it. Also the crud is minerals from the heat of the heating element and some recommend not leaving the element turned on all the time. For me , I'll just leave it on and flush my water heater tank.
My toilet flush stopped..Took valve apart and it was packed solid with "Crud" at screen....That is the cold water line......Explain that?????
