Customer Question

I have a new raptor 425ts. I tried to drain all of the tanks, however the #1 black water tank is still 1/3 full. The drain valves are not marked so I don't know which are grey water and which are the black water. The flushing system only seems to affect black water tank #2. Can you help me with these questions

Hi Larry here. This is a common issue with all RV's. Toilet paper, ect. gets stuck to the sensors insinde the tank. You can purchase a "tank flush" put in the tank through the toile. You then "shake" the RV back and forth to try and dislodge the debris. Hope this helps. Don't forget to rate. Thanks for asking.
