One of the common issues many RVers face is inaccurate readings from their tank sensors. These sensors let you know how full or empty your gray, black, and freshwater tanks are. Over time, these sensors can become coated with debris, leading to false readings. This can be particularly problematic with the black water tank, where toilet paper and waste can create a buildup.
Luckily, there are several effective methods to clean and refresh these sensors. Let's explore them in detail.
1. Commercial Cleaning Solutions:
Many RV and camping stores offer commercial cleaning solutions specifically designed for cleaning tank sensors.
- How-to: Empty your tank, then fill it about a quarter of the way with fresh water. Add the commercial cleaning solution as per the manufacturer’s instructions. Drive the RV or tow the trailer to allow the solution to slosh around and clean the sensors. Finally, empty the tank again.
2. Geo Method:
This method uses water softener and detergent to clean and lubricate tank walls and sensors.
- Ingredients: Water softener (like Calgon) and liquid laundry detergent.
- How-to: After emptying your tank, add 1 cup of water softener and 1 cup of detergent. Fill the tank halfway with water and drive around to mix. Empty and rinse the tank. Not only does this method clean sensors, but it also keeps waste from sticking to the tank walls.
3. Ice Cubes and Water:
Using ice cubes can be a mechanical way to scrub the insides of the tank, including the sensors.
- How-to: Empty your tank. Add a bag of ice cubes into the empty tank through the toilet. Fill the tank a quarter of the way with water and drive around. The sloshing ice cubes will scrub the sensors clean. Afterward, empty the tank again and rinse.
4. Vinegar:
Distilled white vinegar can dissolve mineral deposits which sometimes accumulate on sensors.
- How-to: Empty the tank. Fill it a quarter of the way with water and add 2-3 gallons of distilled white vinegar. Let it sit for several hours (overnight if possible) and then rinse thoroughly.
5. Baking Soda and Hydrogen Peroxide:
Both these ingredients can break down waste and cleanse sensors.
- How-to: Add a cup of baking soda into the tank, followed by 1 gallon of hydrogen peroxide. Fill the tank halfway with water and let it sit for a few hours. Empty and rinse the tank afterward.
6. Preventive Maintenance:
To minimize the frequency of deep cleans:
- Use Quick Dissolving Toilet Paper: This type of toilet paper is designed for RVs and marine use and breaks down more easily.
- Regular Rinsing: Regularly rinse your tanks after emptying. Some RVs come equipped with built-in tank rinsers. If yours doesn't have one, consider installing it or using a wand attachment to ensure thorough rinsing.
- Monitor Chemical Use: Some tank chemicals can cause more harm than good. They might break down waste but also leave residues that affect sensor readings. Stick to enzyme-based treatments and avoid formaldehyde-based products.
Conclusion:
Maintaining accurate tank sensor readings is crucial for a hassle-free RVing experience. By integrating these cleaning methods into your regular maintenance routine and practicing good preventive care, you'll ensure longevity and reliability from your tank sensors. Safe travels and happy RVing!
