How to use an RV dump station

What to bring

• Disposable or dedicated sewer gloves
• A sewer hose (at least 15–20 ft) with a bayonet fitting and a clear elbow so you can see when it runs clean
• A threaded sewer adapter or donut seal for the inlet
• A separate non-potable rinse hose (never use the drinking-water hose for rinsing)
• Tank-safe RV toilet chemicals for afterwards

Step by step

1. Pull up with your drain valves on the dump-station side. Leave room for the next RV to queue behind you.
2. Put on gloves and check that both valves are closed before removing the cap.
3. Connect the hose to the RV outlet first, then seat the other end firmly in the dump inlet (weigh it down or thread it in).
4. Open the black tank valve first. Let it drain completely.
5. Close black, then open the gray tank. Gray water from sinks and showers rinses the hose.
6. Flush the black tank with a built-in flush or a tank wand using the non-potable hose, if the station allows it.
7. Close all valves, disconnect the RV end first and lift the hose so it drains into the inlet.
8. Rinse the hose and the pad with the non-potable rinse water, cap the inlet, and stow your gear.
9. Add a few gallons of water and chemicals to the black tank.

Etiquette and rules

• Many campground stations are for registered guests only, or charge non-campers a fee. Ask first.
• Never fill drinking water from the rinse hose. Look for a separately marked potable spigot.
• Do not dump grease, wipes or chemicals that are not septic-safe.
• Do not leave the hose or gloves behind, and clean up any spill.
• Dumping tanks anywhere other than an approved station or sewer hookup is illegal in every state.

General guidance only. Follow the posted rules at each station.
