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.

A sewer pipe proofer comprising: a section of conduit having an outer diameter substantially smaller than the inner diameter of the sewer pipe being proofed; a fluid spraying nozzle attached to one end of said conduit; a plurality of deformable spacers in the form of rods secured around said conduit

A sewer pipe proofer comprising: a section of conduit having an outer diameter substantially smaller than the inner diameter of the sewer pipe being proofed; a fluid spraying nozzle attached to one end of said conduit; a plurality of deformable spacers in the form of rods secured around said conduit intermediate said ends, said rods being formed to hold said conduit substantially centered and in spaced relationship to the inner wall of said sewer pipe; means removably securing said rods to said conduit with at least one end being free to be slidably displaced in a direction parallel to the axis of said conduit when the rods are deformed; restraining means restraining said at least one free end of said rods; said means removably securing said rods to said conduit being removable to allow easy removal and replacement of individual rods whereby said conduit can be passed through a sewer pipe to test for blockage and easily pass over minor irregularities.
