Frequently Asked Questions (FAQs)
How often should I dump my black tank?
Dump your black tank when it is about two-thirds full to maintain flushing power and prevent buildup. Avoid dumping too frequently with low volumes, as it can lead to clogs and odors.
Can I use regular toilet paper in my RV black tank?
Regular toilet paper can cause clogs and buildup if it doesn’t break down quickly. It’s best to use RV-safe or septic-safe toilet paper that dissolves rapidly and is designed to work well in holding tanks.
How do I know when my black tank sensors are faulty?
If your tank monitor shows inaccurate readings or never indicates empty/full properly, your sensors may be dirty or malfunctioning. Cleaning sensors regularly and following troubleshooting guides can help maintain accuracy.
