RV dump station FAQ
Should I flush my black tank every time I dump it?
A rinse can help, but it is not a reason to force water or use equipment the RV or site does not support.
Short answer
You do not necessarily need a full black-tank flush after every dump. A rinse can help remove residue when your RV has a built-in flush connection or the dump station provides a safe, approved method. Follow the RV and equipment instructions, protect the fresh-water supply from cross-connection, and stop if the tank, valve, or hose shows signs of a blockage or leak.
What to keep in mind
- Use only a backflow-protected, non-potable setup intended for tank rinsing.
- Keep the black-tank valve open while rinsing unless the manufacturer gives a specific timed procedure.
- A flush cannot replace enough water in the tank during normal use; follow your treatment product's directions.
