Last winter I had my van plugged in at home between jobs instead of dropping it at the rented garage. When I pulled away I heard the electric heater fall off the waste tank lid. That has happened before when I have forgotten to take it off there. So I kept going and then heard the cord snap. Fortunately, no damage to anything but the cord.When someone moves the truck without removing the solution line, breaking the nipple behind the QC inside the faceplate.
Thanks Lee........Please don't say "stainless nipple"....because it's better for a disposable pipe nipple to break than an expensive part attached to it.
