Technical Specifications

Aplicaciones

Sewer air pressure testing with controlled bypass flow, DWV code compliance testing, municipal sewer main isolation, storm drain testing, and pipe repair work requiring temporary flow control. The bypass allows water to pass through the plug during testing rather than building up behind it. Always follow Cherne inflation and back-pressure guidelines.
