Buying Guide: Key Considerations For Choosing A 100 Gallon Tank
- Liquid compatibility: Ensure the tank material is suitable for your intended liquid (potable water, non-flammable agricultural chemicals, or other fluids). NSF certification and UV stabilization enhance safety and longevity.
- Physical dimensions and mounting: Check length, width, height, and the ability to position the tank on its side or bottom; consider flat-bottom designs for stable mounting in vehicles or trailers.
- Fittings and plumbing: Review the number and size of inlet/outlet fittings (NPT threads, bulkhead fittings). Plan for hose connections, siphoning, and drainage needs.
- Durability and environment: Look for UV-stabilized, rustproof polyethylene or equivalent materials for outdoor exposure, as well as impact resistance for rugged settings.
- Portability vs. permanence: Foldable or bag-style options offer portability and space savings, while rigid tanks provide long-term durability and easier cleaning.
- Maintenance and cleaning: Large fill caps, integrated drains, and accessible interiors ease routine cleaning and refilling, reducing contamination risks.
- Regulatory and safety considerations: For potable water, prioritize NSF-approved materials and certifications; ensure compatibility with local regulations for storage of liquids on farms or in RVs.
- Cost and availability: Compare total cost of ownership, including fittings and accessories, as well as supplier support and warranty terms.
Across these options, buyers should balance capacity, installation practicality, and intended liquid compatibility. For RV use or portable setups, consider the RecPro and classAcustoms models for potable water storage, while the RomoTech and Norwesco tanks suit outdoor and agricultural environments. The GaeaAuto option is valuable when portability and compact storage are paramount, though it requires careful handling to maintain water quality.
