Yonawlsy Foldable Water Bladder 379 L Collapsible BPA-Free Tank with Dual Ports & Siphon Pump

Yonawlsy Foldable Water Bladder is a collapsible, BPA-free portable tank that stores up to 100 gallons of potable water for emergencies, camping, RV use, gardening, and off-grid living.

When running short on reliable water or preparing for a storm, having a compact, high-capacity reserve removes a major worry. This Yonawlsy bladder inflates into a large, sealed reservoir that fits in a bathtub, garage or yard, and collapses flat for storage when not in use. It’s made from food-grade plastic to keep water clean and includes the fittings needed to fill and dispense easily.

How quickly can I fill and use the Yonawlsy 100-gallon bladder?

Filling is fast with a standard garden hose; the bladder’s wide inlet reduces wait time so you can prepare for emergencies without long delays. Dual ports allow two hoses at once to cut fill time roughly in half. A siphon pump is provided so you can transfer water into smaller containers or pitchers without lifting heavy loads.

• Standard garden hose fills in about 20 minutes (5 GPM)
• Dual-port option cuts fill time to roughly 10–12 minutes
• Included siphon pump and hose clamp for easy dispensing
• Designed to sit in a bathtub or on a flat outdoor surface

Will the water stay clean and safe while stored?

The Yonawlsy bladder uses food-grade, heavy-duty plastic to help preserve potable water and block dust, insects, and pet hair. Because the reservoir seals tightly, it minimizes contamination risks compared with open containers. For best results, fill with treated or municipal water and store out of direct sunlight.

• BPA-free, food-grade construction
• Sealable ports prevent debris entry
• Store indoors or shaded outdoor space to reduce algae risk
• Rinse and dry before long-term storage

How practical is this bladder for different uses like camping, gardening, or disaster prep?

The large capacity and foldable design make this tank versatile: use it as a temporary household reserve during power outages, a water source for gardening or livestock, or a bulk supply for extended RV and off-grid trips. Its lightweight material and included accessories simplify transport, setup, and dispensing across many scenarios. It’s particularly useful where bottled water is scarce or heavy barrels aren’t convenient.

• Suitable for family emergency reserves and hurricane preparedness
• Useful for RVs, boats, and camping setups needing extra freshwater
• Can provide supplemental water for gardens and livestock
• Folds flat for compact storage when empty

What should I know about durability, warranty, and maintenance?

Constructed from heavy-duty materials, the Yonawlsy bladder is built to withstand repeated use if handled according to guidelines. The manufacturer backs the product with a one-year guarantee for peace of mind. Regular rinsing, drying before storage, and avoiding sharp objects will extend the life of the bladder and help maintain water quality.

• Heavy-duty, food-grade plastic resists punctures and wear
• One-year warranty from Yonawlsy for manufacturing issues
• Simple cleaning: rinse, air dry, and store folded
