First-Time RVer Dump-Day Checklist

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

Short version: pack the sewer kit, gloves, and a separate rinse hose. Find a station and check its rules. At the station: valves closed, gloves on, hose to the RV first and the inlet second, black then gray, rinse, cap, stow, wash up. Afterward, add water and treatment to the black tank. Print this page and keep it with your sewer gear.

Your first dump is mostly about not forgetting a step. Experienced RVers don’t do anything magical. They just do the same steps in the same order every time. This checklist is designed to be printed or saved on your phone and followed exactly the first few times. For the reasoning behind each step, read how to use an RV dump station.

1. Pack the kit (once, before the trip)

Sewer hose, about 20 ft total, with bayonet fittings (see the sewer hose guide)
Clear elbow with a 4-in-1 adapter for the inlet
Hose caps for both ends
Spare bayonet gaskets
Disposable nitrile gloves, a full box
Separate non-potable rinse hose, a different color from the drinking hose
Hand sanitizer or wipes, paper towels
Trash bags for used gloves and wipes
Tank treatment, if you use one
Hose support (helpful at campsites)
A dedicated bin or bumper tube that keeps all of this away from drinking-water gear

If you’re building a kit from scratch, a complete hose kit such as the Camco RhinoFLEX 20 ft sewer hose kit covers the hose, elbow, adapter, and caps in one box. Add a box of nitrile gloves and a dedicated rinse hose such as the RhinoFLEX 10 ft clean-out hose with rinser cap. Everything we link is on the gear page.

2. Learn your rig (once, at home)

Find the sewer outlet and the valve handles. Which is black, which is gray?
Check for a second gray tank or a separate galley outlet
Find the black tank flush inlet, if you have one
Check the tank capacities in your manual
Practice attaching the hose to the outlet (with valves closed)
Label the valve handles if they aren’t labeled

3. Before you go to the station

Find a station on the finder or by state, and a backup
Check the fee, hours, and access, or call the operator (see costs and free options)
Close the gray valve a while beforehand if you’re at hookups, so you have gray water to flush the hose
Have cash or a card ready for the fee
Gloves and the sewer kit within easy reach

4. At the station

Read the posted rules
Pull in with the outlet lined up near the inlet; set the parking brake
Gloves on
Confirm both valves are closed
Remove the outlet cap slowly, ready for a few drips
Attach the hose to the RV outlet first; twist to lock; tug-test
Put the elbow into the inlet; secure it (thread in, or weight it down)
Check the hose slopes downhill with no kinks
Open the black valve fully; wait until flow stops; close it
Open the gray valve fully; wait until flow stops; close it
Rinse the black tank if you have a flush or rinser and no one is waiting (non-potable hose only)
Disconnect from the RV; cap the outlet
Lift and drain the hose into the inlet; rinse it
Remove the elbow from the inlet last; cap the hose
Rinse any spills toward the inlet; close the inlet lid; hang up the station hose
Stow sewer gear away from drinking-water gear
Gloves off inside out, into the trash; wash or sanitize hands
Pull forward if someone is waiting

5. After the dump

Add a few gallons of water to the black tank (flush the toilet a few times)
Add tank treatment, if you use one
Note the date and how many days since the last dump, to learn your real capacity
Restock gloves and anything you used up

Never do this

Open a valve before the hose is secured at both ends
Fill your fresh tank from the rinse spigot
Use your drinking-water hose for rinsing
Put gloves, wipes, or trash in the inlet
Dump anywhere but an approved inlet
Run a long tank flush while people are waiting

Tips for your first time

Practice early. If possible, do your first dump at a quiet time, or at a campsite with full hookups, where nobody is waiting.
Bring a helper. One person can watch the elbow and the hose end while the other works the valves.
Go slow. Nobody minds a careful beginner. A rushed one who sprays the pad is another story.
Expect a little mess. A few drips when the cap comes off are normal. That’s what gloves and the rinse hose are for.
When something goes wrong, close the valve. Then check troubleshooting.

Your first full-hookup campsite

A campsite sewer connection uses the same steps, with a few differences:

Use a hose support so the hose slopes steadily from the outlet to the sewer pipe. It will be connected for days.
Many campsite sewer pipes are threaded. Screw in the adapter so it can’t pop out, and use a seal if the campground requires one (some do; check the rules).
Keep the black valve closed until the tank is mostly full, then dump black followed by gray. Leaving the black valve open lets solids build up. See black vs. gray tank.
Close the gray valve a day before you leave so you have gray water to flush the hose on checkout day.

Keeping the kit ready

Inspect the hose for pinholes and cracks at the end of each trip
Check the bayonet gaskets; replace if flattened or cracked
Restock gloves, wipes, and trash bags
Rinse and dry the sewer bin now and then
Keep a spare hose section or extension on long trips

FAQ

What do I need for my first RV dump?

A sewer hose long enough to reach (with bayonet fittings), a clear elbow and inlet adapter, disposable gloves, a separate non-potable rinse hose, hand sanitizer or wipes, and tank treatment if you use one.

Should I practice dumping before my first trip?

If you can, yes. Practicing at a quiet station with tanks partly full of mostly water, or at a campsite with full hookups, takes the pressure off.

What if I forget the order?

Black first, then gray. Black tank holds toilet waste, gray holds sink and shower water. Dumping gray last flushes the hose.

Can I print this checklist?

Yes. Use your browser's print function. The page prints in a simple layout.

What is the most common first-time mistake?

Opening a valve before the hose is secured at both ends, or not checking that both valves are closed before removing the outlet cap.
