Mechanical leak repair clamps installed after what date may not be used as a permanent repair method for plastic pipes?

The date relevant for the use of mechanical leak repair clamps as a permanent repair method for plastic pipes is crucial because it indicates a change in regulations or accepted practices. January 22, 2019, marks the date after which these clamps may not be approved as a permanent solution based on updated standards or guidelines.

This shift likely stems from the understanding that while mechanical clamps can provide a temporary fix, they may not adequately address the long-term integrity and performance required for plastic pipes. It is essential for repairs to be both effective and compliant with industry standards to prevent future leaks and ensure the safety and reliability of the pipeline system.

The other dates listed do not correspond to this regulatory change regarding the permanence of mechanical clamps for plastic pipe repairs. By understanding this context, it becomes apparent that the specified date serves as a critical benchmark for repair practices in the industry.
