Boating or RV life just got cleaner with this Whale gray waste tank. It holds 2.1 gallons (8 liters) and features a smart triple-seal lid that keeps the electronics safe from nasty waste water – way more reliable than old designs. The built-in sensor allows for automatic pump control, and the solid-state switch is protected against water damage. Ready to work with any 12V or 24V pump (up to 20 amps, no relay needed), just mount it on the side. The ports are shaped for easy, accurate drilling: you get two ¾-inch inlets, three 1-inch inlets, and two 1.5-inch inlets, plus ¾-inch and 1-inch outlets. Tank is made from tough MDPE, seals are EPDM/Neoprene, and the lid is glass-filled polypropylene. Backed by a 3-year warranty. Makes waste management on board simpler and less smelly. Installation is straightforward if you’re handy. Keep your bilge clean and your mind at ease.
