What is a “poo pyramid” and how do I prevent it?
A poo pyramid is hardened waste buildup caused by not enough water or dumping too frequently. Prevent it by using plenty of water with each flush, dumping around 2/3 full, and using a digester-style treatment to keep solids liquefied.
When is the best time to dump my RV black tank?
Dump when the tank is about 2/3 full. A fuller tank creates stronger flow, which helps carry solids out and reduces buildup, odors, and clogs.
Why do my black tank sensors read 2/3 full even after dumping?
False readings are usually caused by waste and toilet paper residue stuck to tank walls or sensor probes. A deep clean can remove buildup and restore accurate readings.
How do I restore RV black tank sensor accuracy?
Deep clean the black tank: empty and rinse, add a black tank cleaner like Commando, fill above sensor level, let it soak 12–24 hours (longer is fine), then dump and rinse again.
Do I really need special RV toilet paper?
Not always. If you use a strong digestion-focused treatment like Bio-Pak or Bio-Fresh, many RVers can use regular household toilet paper without problems.
Are enzyme-based RV tank treatments septic safe?
Yes. Enzyme-based treatments are designed to support digestion without disrupting beneficial bacteria, making them a smart option if you dump into a home septic system.
What causes grey tank odors in an RV?
Grey tanks collect sink and shower water, which carries grease, soap scum, and food residue. Over time, this can form organic sludge that creates odors and slow drains.
How do I deodorize and clean my RV grey tank?
Use a grey tank-specific treatment like Elemonate. Drop a tablet into the sink drain, run water briefly to dissolve, and dump the tank regularly to prevent buildup.
