Common Black and Gray Tank Problems

If you’ve spent any time in an RV, you’ve probably encountered at least one of these issues:

1. Clogs Black and gray tank clogs occur when waste, toilet paper, or grease builds up in the tanks or pipes. These blockages can prevent proper drainage and lead to unpleasant backups.
2. Unpleasant Odors Persistent odors can make your RV uncomfortable. Odors often result from waste buildup, improper ventilation, or insufficient chemical treatments.
3. Sensor Malfunctions Tank sensors are designed to show how full your tanks are, but they often get coated with waste or residue. This can lead to inaccurate readings, making it difficult to know when to empty the tanks.

Solutions to RV Tank Problems

While these issues can be frustrating, they are manageable with the right approach. Here are some effective solutions:

1. Preventing and Fixing Clogs

• Flush Regularly: Use a tank flush attachment or built-in flushing system to clean your tanks thoroughly. Flushing prevents waste buildup and keeps your tanks free of debris.
  • Example Product: Camco RV Tornado Rotary Tank Rinser. Available on Amazon and at most RV supply stores.
• Use Proper Toilet Paper: Regular toilet paper doesn’t break down easily in RV tanks. Switch to RV-specific toilet paper to prevent clogs.
  • Example Product: Scott Rapid-Dissolving RV Toilet Paper, available at Walmart or Camping World.
• Add Enzyme Treatments: Enzyme-based treatments help break down waste and toilet paper, reducing the risk of blockages. These treatments also promote healthy bacterial activity inside the tank, preventing buildup over time.
  • Example Product: Unique RV Digest-It Holding Tank Treatment, available online and at RV supply retailers.
• Use a Tank Cleaner: If you’re dealing with persistent clogs, a tank cleaner can dissolve tough buildups. These products are designed for safe and effective cleaning without damaging the tank.
  • Example Product: Valterra Pure Power Blue Tank Cleaner, available at RV stores and online.
• Practice Proper Drain Use: Avoid pouring cooking oils, fats, or grease down your RV sinks. Use strainers to catch food particles and dispose of them in the trash.

2. Managing Odors

• Chemical Treatments: Add RV tank treatments designed to neutralize odors and break down waste. These come in liquid, tablet, or powder form and are essential for odor control.
  • Example Product: Thetford Aqua-Kem, available at RV dealerships and major retailers.
• Ventilation Upgrades: Check your tank’s vent pipes for blockages and ensure proper airflow. Installing a high-quality vent cap, like the 360 Siphon RV Vent Cap, can improve airflow and reduce odors effectively.
• Deodorizing Products: Use activated charcoal or odor-absorbing products in your RV’s bathroom to tackle stubborn smells. Place them in strategic areas, like under the sink or near the toilet.
  • Example Product: DampRid Moisture Absorber, found at hardware stores and Amazon.
• Keep Tanks Hydrated: After emptying your tanks, add a few gallons of water and a tank treatment. This creates a buffer between the tank’s surface and waste, reducing odor buildup.
• Use Baking Soda and Vinegar: A natural and eco-friendly option, mixing baking soda and vinegar in your gray tank can help eliminate grease and odors.

3. Restoring Sensor Accuracy

• Manual Cleaning: Use a tank cleaning wand to remove buildup from the tank walls and sensors. Attach the wand to a garden hose and insert it into the tank for a deep clean.
  • Example Product: Camco Swivel Stik Holding Tank Rinser, available at Camping World.
• Chemical Sensor Cleaners: Use specialized treatments to dissolve buildup and restore sensor accuracy. These cleaners are safe for your tanks and work overnight to tackle tough residues.
  • Example Product: Happy Campers Sensor Cleaner, available at online RV stores.
• Try Ice Cube Method: For a DIY approach, add a bag of ice cubes to your black tank along with water and drive around. The movement helps scrub the walls and sensors clean.
• Regular Maintenance: Avoid flushing non-biodegradable items or grease down your drains to minimize residue. Incorporate routine tank cleaning into your RV maintenance schedule to prevent future issues.
• Sensor Upgrades: If your sensors frequently malfunction despite cleaning, consider upgrading to more reliable models like SeeLevel tank monitoring systems, which use external sensors for accurate readings.

Tips for Long-Term Tank Maintenance

Keeping your black and gray tanks in good condition requires ongoing care. Follow these tips for worry-free RVing:

• Dump Regularly: Don’t wait until your tanks are full. Dumping when they’re around 2/3 full ensures better flow and prevents waste from solidifying.
• Use a Clear Elbow Fitting: This handy device lets you see when the water runs clear during flushing, ensuring your tanks are completely clean.
  • Example Product: Camco RhinoFLEX Clear Swivel Elbow, available at Amazon and RV supply stores.
• Invest in Quality Hoses: A durable sewer hose makes the dumping process cleaner and easier.
  • Example Product: RhinoFLEX Sewer Hose Kit, available online or at camping retailers.
• Educate Guests: If friends or family use your RV’s bathroom, explain the importance of using RV-safe toilet paper and avoiding non-flushable items.
