Should I leave water in my holding tanks when I am not using my RV?

If you are leaving or storing your RV for a short period of time (a few days to a couple of weeks), then it is okay to leave water (not waste!) in your holding tanks. In fact, 3-5 gallons will help keep things lubricated and you’ll be ready for traveling to your next destination or continued use of the RV where it is located.

Longer-term, no, we do not recommend that you keep water in your tanks, and, certainly not any waste. If you are in an area where temperatures could drop below freezing for any amount of time, you can see the danger of allowing any liquid to freeze and potentially damage waste system components.
