In this video, we provide an informative walkthrough of the DN100-DN1000 High Pressure Pipe Test Plug for sewer tightness testing. You will see how these plugs are used to temporarily seal sections of sewer lines, enabling precise pressure testing to detect leaks. We demonstrate the step-by-step process from plug insertion and inflation to pressure monitoring and leak localization, highlighting the critical role this testing plays in protecting infrastructure and the environment.
