Jinlong PVC Flexible Water Tank is engineered for diverse scenarios including agricultural irrigation, emergency water supply, field operations, fire rescue and RV travel, serving as a collapsible and ready‑to‑use portable water‑storage unit.

Unlike bulky space‑consuming rigid containers, it is constructed from high‑strength food‑grade PVC coated polyester scrim. The dual‑side PVC coating bonded with reinforced polyester mesh delivers great flexibility and outstanding puncture resistance. UV‑stabilized material works steadily within ‑30℃ to 70℃ to withstand harsh climates. Industrial high‑frequency heat‑welding ensures seams stronger than base material to prevent leakage, granting 5‑8 years service life under normal conditions.

Focused on real‑world user pain points, it adopts standard NPT threaded ports compatible with most water pumps, quick connectors and garden hoses for direct connection without extra adapters. The inner drain pipe reaches the lowest point. Combined with flat pillow‑type design, it enables thorough draining with no residual water to avoid freezing in winter. Anti‑slip texture and fastening holes at the bottom prevent shifting and rolling. When empty, it folds compactly for easy storage in car trunks, lockers or backpacks. Custom capacities and fittings are available. We support OEM and ODM services to meet various project requirements. Jinlong brings accessible clean water wherever you go.

FAQ of PVC Flexible Water Tank

Q: Is PVC flexible water tank suitable for drinking‑water storage?

A: Yes. Jinlong PVC flexible water tank is made of food‑grade PVC coated polyester scrim, compliant with drinking‑water standards and free of BPA and phthalates. Soak in clean water for 12 hours and rinse before first use.

Q: Can ports connect directly to garden hoses or water pumps?

A: Yes. Standard NPT threaded ports fit most garden hoses, quick connectors and water pumps without adapters. American fire‑fighting couplings, clamp‑type fittings and other custom ports are available.

Q: Can water drain completely when water volume is low?

A: Yes. The outlet pipe reaches the lowest point of the tank. Combined with flat flexible‑structure guidance, water can flow out smoothly even at low volume, leaving less than 1‑liter residual water.

Q: Will freezing damage PVC flexible water tank under low‑temperature conditions?

A: Do not store water inside when freezing. Water expands about 9% when frozen, and repeated freeze‑thaw cycles accelerate material aging. If used below zero, add compatible antifreeze or use heating tapes. Drain, dry and fold for storage when not in use.

Q: Will long‑term sunlight exposure cause cracking?

A: UV‑stabilized material effectively slows aging under outdoor sunlight. Industrial high‑frequency welding delivers seams stronger than base material for long service life. Fold and store in cool place when idle for better durability.

Q: Can punctured tank be repaired?

A: Yes. Use special PVC repair kit with patch and glue. Clean damaged area, apply glue and press the patch firmly, leave it for 24 hours before reuse. Contact our factory for professional hot‑welding repair for large‑area damage.

Q: What PVC flexible water tank shapes do you supply?

A: Pillow type, onion type and long‑strip type are available to fit different site conditions.

Q: Do you support OEM & ODM services?

A: Yes. Custom capacity, dimensions and fittings are available for project orders.
