How often should I dump my tanks?

The plain answer is when they are full. Your RV’s holding tanks are large, squarish boxes. The more volume in them, the better they drain out and carry any waste out through the drain pipe. A fuller tank provides more down pressure, resulting in the familiar swirl or vortex you see in your home toilet. That swirling water helps to clean your tanks.

If your tank isn’t full (according to the sensors or whatever method you use) and it’s time to empty them (perhaps you are leaving your RV park or you just want to empty them), add extra water, either down the toilet (for the black tank) or shower or sink (for the gray). Try to get them 80% to 100% full.
