GUIDE
PVC vs TPU Water Bladder Tank — Which Material for Your Job?
PVC and TPU are both flexible bladder materials, but they are not interchangeable. For non-potable water storage — irrigation, construction site water, emergency reserves — PVC is the standard choice: lower cost, proven for water, and available in 5,000–50,000L.
