Abstract

In combination with a sewer and drain pipe plug testing device including an expandable plug having a flexible strap-like member secured at a one end of the expandable plug which enables removal of the expandable plug from a sewer or drain pipe after testing is complete. The improvement comprises a handle-like member secured to the opposite end of the strap-like member. The handle-like member would have a predetermined size which is at least large enough to prevent entry into the open sewer and drain pipe. There is at least one aperture formed through the handle-like member that has a predetermined shape substantially identical to a nut-like portion of a plug member disposed in the sewer and drain pipe to enable tightening and loosening the plug member into and from, respectively, the sewer and drain pipe. Also, there is at least one round threaded aperture drilled into the handle-like member that intersects the aperture formed into the handle-like member for engaging the nut of a threaded closure plug. This provides for a wing nut bolt to threadedly engage the round aperture and engage the nut of the threaded closure plug while the handle-like member is in contact with the nut of a…
