Proper Dumping Procedure
Prepare Your Equipment
Put on rubber gloves. Have your sewer hose, adapters, clear elbow, and hose support ready. Check that valves are closed.
Connect Sewer Hose
Attach hose to RV outlet first, then to dump station. Ensure secure connection. Use clear elbow to monitor flow if available.
Dump Black Tank FIRST
Critical: Always dump black tank before gray tank. Open black valve fully, let drain completely (clear elbow turns clear).
Dump Gray Tank Second
Close black valve, open gray valve. Gray water helps rinse out the hose. Let drain completely.
Flush Black Tank (Optional)
If you have a tank flush system, close gray valve, run flush for 5-10 minutes, dump black tank again. This removes solids.
Disconnect & Clean
Close all valves. Disconnect from dump station first, then RV. Rinse hose exterior, store properly. Remove gloves, wash hands thoroughly.
Add Tank Treatment
Add RV toilet paper and tank treatment (Happy Campers, Unique, etc.) to black tank. Add water to start new cycle.

Common Questions
How often should I dump my tanks?
Dump when your black tank is 2/3 to 3/4 full. Never let it get completely full. For most RVers with 2-4 people, this means every 3-7 days. Gray tanks can go longer but shouldn't sit full as it can cause odors.
Why dump black tank first?
Black tank contains solid waste. If you dump gray first, you'll have solid waste residue in your hose with no way to rinse it out. Gray water (from sinks/shower) is cleaner and rinses the hose after dumping black waste.
Can I dump at home?
Yes, if you have a cleanout access point and a macerator pump. Never dump into a septic tank unless it's designed for it. Check local regulations - some areas prohibit RV dumping into residential sewers.
What causes tank sensor problems?
Toilet paper and waste buildup on sensors causes false readings. Use RV-specific toilet paper, add tank treatments, and perform periodic deep cleans with ice cubes, Dawn dish soap, or commercial cleaners. A tank rinser helps prevent buildup.
Is a macerator pump worth it?
For frequent boondockers: absolutely. Macerators let you dump uphill, use smaller hoses (longer reach), access home cleanouts, and dump faster. They typically pay for themselves within 1-2 years through increased access to free/cheap dump locations.
What's the best tank treatment?
Popular options: Happy Campers (enzyme-based, eco-friendly), Unique Method (bacteria-based), or Geo Method (DIY: Calgon + Dawn). Avoid formaldehyde-based treatments - they're harsh on seals and the environment.
Can I leave my black tank valve open at a campground?
NEVER leave the black tank valve open, even with full hookups. Liquids drain faster than solids, creating a "poop pyramid" that's difficult to remove. Always keep it closed until you're ready to dump.
How do I winterize my tanks?
Dump and flush tanks completely. Add RV antifreeze (pink, non-toxic) to prevent freezing. Run antifreeze through all drains. For extended storage in freezing temps, consider removing and storing tanks indoors or using tank heaters.
