Frequently Asked Questions

AI
Gray water tanks hold wastewater from sinks and showers, which is relatively clean. Black water tanks store waste from marine toilets, requiring more robust materials and often a macerator pump for efficient emptying due to the nature of the contents.
A macerator pump is highly recommended if your tank is located far from the discharge point or if you need to pump waste upward. It grinds solids into a slurry, allowing for easier and faster emptying through smaller diameter hoses compared to gravity systems.
Rinse the tank thoroughly with fresh water after each use. Use a dedicated marine tank cleaner to eliminate odors and bacteria. Ensure all caps and seals are tight to prevent leaks during transport, and store the tank in a shaded, ventilated area when not in use.
