RV Dump Station Etiquette and Rules

Guide · Updated 2026-11-09 · General guidance; rules vary by state, park, and operator, so follow posted signs.

Short version: be ready before your turn, keep your drinking-water gear far away from the dump side, put nothing in the inlet except tank contents and rinse water, keep it quick if people are waiting, pay what the sign asks, and leave the pad cleaner than you found it.

Dump stations are shared, and they work because most people follow a handful of simple habits. Some are posted rules and some are just courtesy. Rules differ from one station to the next, depending on the city, state, park system, campground, or business that runs it. So the most important habit is the first one: read the sign at the station. Everything below is general practice. Where the posted rules say something different, follow the posted rules.

Before your turn: get ready while you wait

Very few people mind waiting at a dump station. What wears on a line is the person who pulls up and only then starts digging for gloves and a hose. While you wait:

Put your gloves where you can reach them.
Take the sewer hose and adapter out of storage if you can do it without blocking anyone.
Have the fee ready if the station charges one.
Decide ahead of time whether you'll do a quick dump or a full tank flush. If there’s a line, it should be a quick dump.

If there are two lanes, use the one that lines up with your outlet side. Pulling into a lane facing the wrong way and stretching the hose across the pad slows everyone down.

The two spigots: rinse water vs. drinking water

This is the rule that matters most for your health and everyone else’s. Many stations have a hose or spigot right by the inlet, often labeled non-potable or “not for drinking.” That water is for rinsing hoses, tanks, and the pad. People push it into sewer hoses and wash the pad down with it. Treat it as contaminated.

Never fill your fresh tank or a drinking jug from the rinse spigot.
If the station also has a potable water spigot, it is usually set apart and clearly labeled. Fill from it only with your own drinking-water hose, and keep that hose’s end off the ground and away from the inlet.
Never screw your drinking hose onto the rinse spigot, “just to check.” Threads carry contamination.
Keep your own rinse hose a different color from your drinking hose so they can’t get swapped.
Some people also wipe the potable spigot with a sanitizing wipe before connecting. It’s a reasonable habit, but it doesn’t make a non-potable spigot safe.

If there is no clearly marked potable spigot, don’t guess. Fill your fresh tank somewhere else.

What goes in the inlet (and what doesn’t)

A dump station inlet is built for RV holding tank contents and rinse water. That’s it.

OK: black and gray tank contents, rinse water, contents of a portable toilet cassette or waste tote where the station allows it.
Not OK: gloves, wipes (even “flushable” ones), paper towels, cigarette butts, food scraps, cooking grease, motor oil or coolant, pet waste bags, kitty litter, diapers, or household trash.

Wipes and gloves are the usual cause when a station backs up, and when one backs up, the operator may close it. Then nobody gets to use it.

Pet waste deserves its own mention. Bagged dog waste goes in a trash can, not in the inlet. Most stations are not set up for it, and the bags cause clogs. Some stations post that they don’t provide trash cans at all. If so, take your trash with you.

Keep it quick when there’s a line

A routine dump, black then gray with a quick hose rinse, doesn’t take long once you’ve done it a few times. A full black tank flush takes a lot longer. Both are fine; the question is timing.

If no one is waiting, take the time you need, within any posted limit.
If someone pulls up behind you, finish what you’re doing, skip the extended flush, and save it for a full-hookup site or a quieter moment.
Once you’ve disconnected, pull forward out of the lane to coil hoses, put things away, and fill out paperwork, if there’s space to do so safely.

Some busy stations post time limits or don’t allow tank flushing. Follow what’s posted.

Fees, donation boxes, and honesty

Dump stations are run by many different kinds of operators: municipal parks, state and federal recreation areas, private campgrounds, travel centers, and the occasional sewage treatment plant. Some are free, some charge everyone, some are free for guests and charge non-guests, and some ask for a donation. We don’t list dollar amounts on this site, because fees change and differ by operator. See our guide to dump station costs and free options.

Whatever the sign says, do that. Use the honor box if there is one, pay the attendant if there is one, and don’t use a guests-only station if you aren’t a guest. Free and low-cost stations stay open when people respect them, and they can close when people don’t.

Leave the pad clean

Spills happen. If something splashes, rinse it toward the inlet with the station’s rinse hose before you go.
Put the station’s rinse hose back where it was, hung up or coiled, not lying in the inlet.
Close the inlet lid or cap.
Pick up anything you dropped, such as caps, gloves, or wipe packets.

Safety around the station

Set your parking brake. Pads can be sloped.
Watch for kids and pets. A dump station is no place for either to explore.
Don’t smoke over an open inlet. Sewer gas is unpleasant at best.
Wear gloves, and wash or sanitize your hands before you touch anything else.

When the station is broken, closed, or full

If the inlet is backed up, the lid is chained shut, or there’s a closed sign, don’t try to make it work, and never dump on the ground nearby. Find the next option on the dump station finder or browse by state. If the station lists an operator contact, letting them know helps the next person. If our listing is out of date, you can submit a correction.

FAQ

Can I fill my fresh water tank at the dump station?

Only from a spigot that is clearly marked as potable or drinking water, using your own drinking-water hose. The rinse spigot near the inlet is for rinsing only. If there is no marked potable spigot, fill your fresh tank somewhere else.

Is it rude to flush my black tank at a dump station?

Not if nobody is waiting. A quick rinse is normal. A long, multi-cycle tank flush while others are in line is the one thing most RVers wish people would save for a full-hookup site.

Can I throw my gloves away in the dump station inlet?

No. Gloves, wipes, and trash can clog the station. Use a trash can if one is provided, or bag them and take them with you.

What if the dump station is free but has a donation box?

Then it is up to you, but donations often help keep free stations open. Follow whatever the posted sign says.

Do dump stations have time limits?

Some do and some don't. Busy stations at parks or travel centers may post limits or ask you not to flush tanks. Follow the posted rules at that specific station.
