An apparatus for pressure testing a plumbing installation includes a flexible cylindrical body having a peripheral sidewall, a closed end and an open end. A positioning flange extends outwardly from the peripheral sidewall at the open end to facilitate positioning cylindrical body with an end of a pipe into which the cylindrical body has been inserted. An end wall is positioned at the closed end that is. The end wall is curved inwardly and has an inward cylindrical flow channel closed by a partially removable plug. A gripping strip is secured to the partially removable plug that closes an inward cylindrical plug and extends through and past the open end of the cylindrical body, such that upon a force being exerting upon the gripping strip the plug lifts to open the cylindrical flow channel and upon a force continuing to be exerted upon the gripping strip the cylindrical body rolls inside out thereby enabling the cylindrical body to be removed from the pipe.
