It has high impact resistance and is not easy to break under the impact of rain; it is UV resistant, non-toxic and will not release harmful substances. PP material is better than PVC material of other similar products. Adjustable Water Collection: The valve of the rainwater collection system can adjust the amount of rainwater collection.
