A Guide to Proper RV Dump Station Use

It is probably the least pleasant task of RVing. But the trip to the dump station is the price you pay for using your own bathroom instead of the semi-open-air, never-clean-enough, and not particularly private public campground bathrooms. When the time comes, you want things to go as smoothly and pleasantly as possible for both you and the people who come next. You don’t want to be “that guy” that everyone in the campground knows left a mess. With the help of RV Life Escapes, Valley RV Supercenter offers advice on making the dump station visit as smooth, orderly, and clean as possible.

Before Arriving at the Dump Station

Having the best possible experience starts before you head to the dump station. Ideally, your black tank should be about ¾ full to ensure enough gravitational pressure for a thorough flush. Make sure your gray tank is at least half full, and the fuller, the better. The water from your shower and sinks will be necessary to rinse out your hose, which will still be full of residue from the black tank. If your gray tank isn’t at least half full as the time to dump approaches, find excuses to use your sink or shower until it is.

The other most important pre-dump rule is to have all your dump gear in a dedicated plastic bin. This includes fittings, hose, hose support, gloves, sanitizer, and anything else you need, all stored in a single bin that holds nothing else. This accomplishes three things:

1. None of these items comes in contact with your other camping gear

1. You won’t take time at the station looking for items

1. You won’t forget anything necessary

Finally, make sure the bin is immediately accessible before you leave for the dump station.

At the Station

Naturally, when you arrive at the dump station, make sure your sewer outlet is facing the site inlet. The first thing to do when you get out is to put on a set of disposable gloves. No one plans for a messy surprise at the station, but they can happen to even the most experienced RVers. Now it’s time to pull out your equipment. Two things to keep in mind are to use a hose support so that everything flows more easily and to prevent you from having to pick up the hose at the end of the dump to empty it.

Make sure your elbow in the inlet is transparent. As much as you would rather not see what’s going through there, the transparency lets you know when the tanks have been entirely emptied into the station, because one of the worst dump station mistakes is disconnecting too soon.

The other major mistake at dump stations is failing to properly secure connections to both your RV and the inlet. No matter how many times you have performed the task, always check and recheck that the connections are secure.

It is important to dump the black tank first. You know what’s in it, and it is far less pleasant than the gray tank contents. Don’t rush the process, as you want to remove as much as possible. Watch the clear elbow and wait for that final gurgle that indicates the flow has completed.

Now is the time to empty the gray tank, which will flush out the hose and connections and remove any lingering black tank debris. This will reduce odors from your equipment.

If you have a tank rinser or flush connection, feel free to use it to clean the black tank, but don’t spend more than 20 minutes on it if others are waiting—it’s best to keep things moving smoothly. Experienced RVers typically give it a quick rinse and then clean it thoroughly later if needed. The longer the line behind you, the less rinsing you should do.

Before You Go

Finally, if, despite your best efforts, any spillage occurs, have a dedicated dump hose to clean the area for the next user. Sewage dumping is even worse when the station isn’t clean. Never use a potable water spigot to rinse your dump hose. Any backup can contaminate the spigot and prevent the water from being truly potable for some time.

At the end, pack everything up, put it back in the dedicated bin, and check again. You would be surprised how many people manage to drive off with the hose still attached. Check everything a second time before you remove and dispose of the gloves, rub your hands with hand sanitizer, and drive off.

Dumping your RV tanks will never be fun, but it can be straightforward and mess-free with proper prep, the right equipment, and respectful campground behavior. When we handle shared spaces considerately, it benefits everyone in the RV community and makes traveling easier and more enjoyable.
