Buying Guide: Key Considerations for Boat and RV Fresh Water Tanks
- Capacity vs. space: Larger tanks offer more water between fills but require more mounting space. Balance your trip length with available RV or boat space.
- Material safety: Look for BPA-free materials and NSF/IAPMO standards to ensure potable water safety. Check for tamper-evident seals and sanitary fittings.
- Fittings and compatibility: Confirm the number and size of fittings (usually 1.5″ NPT and 0.5″ NPT) to match your hoses and manifolds. Consider dual fittings for flexible routing.
- Installation options: Tanks with multiple fitting locations and the ability to sit on either side simplify installation on irregular spaces.
- Durability and warranty: Weather-resistant plastics and impact resistance improve longevity for vehicles exposed to road conditions and weather.
- Emergency considerations: If traveling in remote areas, consider a larger capacity or ready-to-use pump kit for easier access to water on demand.
