Technical Specifications

Applications

DWV pressure testing for code compliance, residential and commercial plumbing inspections, stack testing, and sewer air tests. The pneumatic design seals quickly and conforms to out-of-round pipe — faster than mechanical plugs for multi-plug test setups. Always follow Cherne inflation guidelines and never exceed rated inflation pressure.
