36 Gallon RV Fresh Water Tank - Potable Water Storage for RVs

In this review of the 36 Gallon RV Fresh Water Tank the bottom line is simple: this is a practical, no-frills potable water tank for RV owners who need reliable capacity and straightforward installation. The tank is best for campers, trailers, motorhomes and tiny houses that require a sanitary, BPA-free reservoir for drinking, cooking, showering and dishwashing. The single biggest reason to buy is the combination of a full 36 gallon capacity and OEM-style molded fittings that make it easy to plumb into an existing freshwater system.

Key Features

• Made in USA: The tank is manufactured domestically, which supports consistent quality control and traceable materials.
• BPA-Free construction: The potable material ensures stored water remains safe for drinking and food preparation.
• Multiple built-in fittings: Two 1.5 in balloon style female NPT and two 0.5 in female NPT fittings provide flexible plumbing options during installation.
• Durable plastics: Weather-resistant and impact-resistant materials help the tank withstand typical RV vibration and handling.
• Sanitary, leak-proof design: The molded construction meets IAPMO standards to help maintain water hygiene in mobile applications.
• Cube shape and measured footprint: The 37 in x 16 in x 15 in dimensions make it straightforward to plan mounting space underbeds or in storage bays.

Who It's For

The tank suits RV owners who need a mid-range capacity fresh water solution and prefer a ready-made, certified tank rather than fabricating a DIY container. It is particularly useful for tear drop trailers, campers, food trucks and tiny houses that benefit from a compact cube shape and multiple factory fittings.

Those who should look elsewhere include installations requiring pressurized tanks or integrated hardware; this model must not be pressurized and it ships without mounting brackets, gate valves, hoses or additional fittings. Buyers wanting a complete kit with valves and hoses will need to purchase those items separately.
