ITRAZ TPU Water Storage Bladder (60 gal)
The ITRAZ TPU bladder uses a food-grade TPU coating and 1000D polyester fabric, ensuring BPA-free and odorless water storage. It folds down to save space when empty and can support substantial weight when filled.

Caution: Folding and storage require dry, clean drying to prevent mold; fill within recommended capacity to avoid over-expansion in cold conditions.

Best for those who need big capacity and prefer foldable storage.
- Best for high-capacity needs without committing to a rigid tank.
- Choose this if you want a foldable solution that can be tucked away when not in use.
Caution: PVC materials may require careful handling to avoid punctures during rough travel; store away from sharp objects.
Buying Guide: Key Considerations For RV Water Storage
Capacity vs. space: Balance the amount of water you want to carry with the space available in your RV. Bladders offer more flexibility, while rigid tanks provide stable plumbing and structural support.
Material safety: For potable water, look for BPA-free materials and food-grade coatings. This ensures the water remains clean and tastes normal during storage.
Installation options: Check fittings and connection types. Tanks with multiple NPT fittings provide versatile mounting and plumbing routes for different RV layouts.
Durability and climate: If you travel in varied climates, consider UV resistance and temperature tolerance. Some tanks are designed for outdoor exposure; others are built to resist cracking in cold weather.
Portability and storage: Foldable bladders save space when not in use but require dry storage. Rigid tanks are heavier but are often easier to install and keep in place during travel.
Maintenance: Empty and dry storage is recommended between uses to prevent mold and odor. Sanitary designs reduce the risk of contamination in potable-water storage.
