9 Gallon RV Fresh Water Tank - Potable Cube Tank for RVs

In this review the 9 Gallon RV Fresh Water Tank is examined as a simple, no-frills potable water option for campers, trailers, motorhomes and conversion projects. The bottom line: it is best for owners who need a compact, sanitary storage solution that fits tight spaces and is straightforward to install; the single biggest reason to buy is the combination of a cube shape with built-in fittings that make installation flexible and keep drinking water safe.

Key Features

• Made in USA: Manufactured domestically from BPA-Free materials to provide confidence in potable water storage and material safety.
• Compact cube shape: The 17 in x 14 in x 10 in dimensions give a 9 gallon capacity that fits in small compartments and cargo trailer conversions without wasting space.
• Multiple built-in fittings: Comes with two 1.5 in balloon style threaded female NPT fittings and two 0.5 in threaded female NPT fittings to allow several plumbing layouts and easy connection options.
• Durable construction: Weather resistant and impact resistant plastics keep the tank sanitary and leak-proof during normal RV use.
• IAPMO and QAI certified: The tank meets recognized sanitary standards, which helps ensure clean water for drinking, cooking, showering and washing dishes.

Who It's For

This tank is ideal for RV owners, tiny house builders and food truck operators who need a small, reliable freshwater reservoir that will not take up a lot of space but still provide potable water for drinking, cooking and showering. It suits DIY trailer conversions where accurate dimensions and multiple fitting locations matter.

Those who need large onboard capacity, integrated mounting hardware or pressurized holding tanks should look elsewhere; the tank is not designed to be pressurized, does not include external fittings or mounting hardware, and should be emptied and cleaned regularly when not in use.
