Certain practices should be strictly avoided to maintain the structural integrity and performance of Ashirvad Dynaflo PVC-O pipes. These pipes should not be used for hot water applications, as they are not designed to withstand high temperatures. Avoid dropping or dragging the pipes on rough surfaces, which can cause surface damage or cracks. Additionally, never expose the pipes to open flames or high heat sources, and always stay within the recommended pressure limits to prevent system failure.
