发明名称 Sewer pipe tester
摘要 A device for testing sewer pipes comprised of an elongated section of conduit having a nozzle on one end and a coupling on the other end for coupling hose to feed the device into a sewer pipe and fluid to the nozzle. Intermediate the ends of the elongated section of conduit are a plurality of the deformable skids adapted to maintain the elongated section of conduit coaxial with the pipe being tested. The deformable skids allow the device to easily pass through the pipe being tested and to identify any blockages, irregularities or deformities. The tool can be used to test the true integrity of any pipe.
