Buying Guide
- Material and safety: Look for BPA-free and NSF-approved materials for drinking water storage to avoid chemical leaching and ensure potable water safety.
- Fittings and compatibility: Check the number and size of NPT fittings (1.5″ and 0.5″ are common). Ensure the tank can be mounted in your RV or camper with your existing plumbing configuration.
- Mounting options: Consider tanks with multiple fitting locations or the ability to rotate the tank to fit tight spaces. The ability to sit on any side helps with vehicle orientation and storage constraints.
- Durability: Weather resistance, impact resistance, and solid sealing reduce the risk of leaks during travel and exposure to outdoor environments.
- Capacity vs. usage: A 5-gallon tank balances portability and water storage for short trips, but assess your typical water usage (drinking, cooking, cleaning) to ensure adequacy.
- Combination kits: Some options pair a fresh water tank with gray water reservoirs. If your setup requires both, these bundles can simplify installation.
- Maintenance and cleaning: Choose tanks with easy-to-clean interiors and accessible ports. Look for tanks that are compatible with standard RV cleaning routines.
- Warranty and standards: Preference for products meeting IAPMO and NSF standards provides an additional layer of assurance for safety and reliability.
Bottom-line considerations include the intended use (RV living vs. temporary camping), space constraints, and whether you need a standalone tank or a combined pack. Evaluating the included fittings, mounting flexibility, and material safety helps ensure a long-lasting, potable water solution that suits outdoor adventures and mobile living.
