Buying Guide: Key Considerations For Above-Ground Potable Water Storage
Capacity and use-case: For RV travel, choose a tank sized to cover your typical trip length without frequent refills. Caseloaded needs, such as cooking, cleaning, and showering, may justify larger capacities. Collapsible bladders offer portability and space savings, while rigid tanks provide sturdiness and easier mounting.
Material safety and hygiene: Opt for BPA-free materials and water-contact ratings appropriate for drinking water. Ensure the tank or bladder is designed for potable water and easy to clean or sanitize. Look for leak-proof construction, smooth interior surfaces, and compliance with relevant standards (e.g., IAPMO).
Installation flexibility: Consider built-in fittings and available mounting options. Rigid tanks often come with standard NPT fittings for straightforward installation, while bladders rely on hoses, spigots, and connectors. Access to multiple inlet/outlet options can simplify routing and plumbing.
Durability and climate resilience: Weather- and impact-resistant plastics suit outdoor use in varying climates. If storing in hot sun or cold conditions, choose materials rated for broad temperature ranges and UV resistance where possible.
Portability and storage: Collapsible bladders save space when not in use and are lighter to transport, making them ideal for emergency kits or off-grid adventures. Rigid tanks provide robust permanence in a fixed installation but require more space and mounting considerations.
Maintenance and sanitization: Plan for periodic cleaning, disinfection, and inspection for leaks or cracks. Flexible bladders should be checked for wear at seams, and rigid tanks should be inspected for fittings and tank integrity to prevent contamination.
Cost and availability: Compare upfront cost, maintenance needs, and spare parts availability (fittings, hoses, caps). USA-made options may appeal for quality assurance, while certain brands emphasize quick installation and ease of replacement parts.
Usage versatility: If you anticipate off-grid use, consider options with higher capacities or robust emergency storage capabilities. Some bladders are designed for gardening or irrigation in addition to potable water needs, which can influence material selection and design features.
Environmental and space considerations: Homes, RVs, and cabins vary in space. Choose a system that aligns with your available area, whether you prioritize a compact, stackable 55-gallon option for a secure pantry-like setup or a larger 100-gallon bladder for extended trips.
