This 21-gallon tank bridges the gap between compact and mid-size waste storage. Left-drain positioning suits many conventional RV floor plans, and rigid ABS plastic with solvent-welded seams guarantees long-term reliability whether holding black waste or grey water.

Flange mounting and level sensors streamline installation and reduce guesswork about fill levels. Included spigot fittings connect directly to your waste lines without additional parts.
