Buying Guide
What to consider when choosing a 100 gallon tank for mixing
- Liquid type: Food-grade or potable water tanks require NSF/food-safe materials. For non-potable liquids, consider chemical compatibility with the material (PVC, polyethylene, or poly blends).
- Rigidity vs. collapsibility: Rigid tanks offer stability and fixed dimensions, while collapsible bladders save space and weight but may require careful handling.
- Mounting and placement: Some tanks are designed for outdoor use, others for RV interiors or trailers. Check dimensions and access points (fill/drain ports) to fit your space.
- Valves and fittings: Look for tanks with built-in fittings or compatible bulkhead fittings if you plan to connect hoses, pumps, or filtration systems.
- Durability: UV resistance, impact resistance, and temperature range impact long-term performance in outdoor or workshop settings.
- Maintenance: Ease of cleaning, accessibility of the interior, and availability of replacement parts affect daily use.
Common scenarios and which model fits
- Agricultural use and livestock watering: Choose a rugged, US-made stock tank or a heavy-duty bladder with a stable base for outdoor use.
- Portable outdoor storage: A UV-stabilized poly tank with clear volume markings is ideal for visibility and transportability.
- Emergency water storage: A collapsible bladder with easy fill/empty access and transparent material helps quick deployment and monitoring.
- RV and travel needs: A 100 gallon tank designed for RV plumbing, with compatible fittings and lightweight materials, supports long trips.
Installation and safety tips
- Verify liquid compatibility before mixing or storing chemicals or fuel in any tank to prevent degradation or safety hazards.
- For rigid tanks, plan for proper anchoring and drainage to avoid tipping or spills in windy environments.
- Regularly inspect seals and fittings for leaks, especially at bulkheads and valve connections.
- Label contents clearly and maintain a simple maintenance schedule to extend tank life.
