19 Gallon RV Fresh Water Tank - Compact Potable Storage for RVs

In this review the 19 Gallon RV Fresh Water Tank is assessed as a compact potable storage option for smaller rigs and tight installation spaces. The bottom line: it is best for campers, trailers, tiny houses, and motorhomes that need a sanitary, easy to fit freshwater reservoir without complex plumbing. The reviewer found the tank's build quality, cube shape and multiple built-in fittings to be the single biggest reason to choose it when space and reliable potable storage are priorities.

Key Features

• Made in USA: Manufactured in Elkhart County, Indiana, the tank provides domestic production traceability and consistent quality control for buyers who prioritize origin.
• BPA-Free Materials: The tank is produced from sanitary, BPA-Free plastics so stored water remains suitable for drinking and cooking without chemical concerns.
• Compact Cube Shape: At 30 in x 16 in x 10 in the cube form factor offers predictable fit in low or narrow compartments, making it easier to plan installations in tight spaces.
• Multiple Built-in Fittings: Two 1.5 in balloon style female NPT fittings and two 0.5 in female NPT fittings allow flexible hookup locations and simplify routing for common freshwater uses.
• Durable Construction: Weather and impact resistant plastics help the tank resist typical RV vibrations and road conditions, contributing to longevity and leak resistance when installed properly.
• IAPMO and QAI Certifications: Certification and quality checks mean the tank meets recognized standards for potable water storage in recreational vehicles.

Who It's For

The 19 gallon freshwater tank is aimed at RV owners, camper builders and tiny house owners who need a compact, tested potable water reservoir that fits narrow cabinets or under-bed cavities. It suits people replacing an old tank where accurate dimensions and multiple fitting options make retrofit straightforward.

People who need pressurized systems, integral hardware, or preassembled plumbing should look elsewhere; the tank does not include mounting hardware, gate valves, hoses, or fittings and must not be pressurized or hung by straps.
