Abstract:
1. An apparatus for pressure testing a plumbing installation, comprising: a flexible cylindrical body having a peripheral cylindrical sidewall, a closed end, and an open end; a positioning flange extending outwardly from the peripheral cylindrical sidewall at the open end to facilitate positioning the cylindrical body within an end of a pipe into which the cylindrical body has been inserted, the peripheral cylindrical sidewall engaging an inner surface of the pipe; an end wall at the closed end, the end wall being curved inwardly where the end wall connects to the peripheral cylindrical sidewall and having an inward cylindrical flow channel closed by a partially removable plug; and a gripping strip secured to the partially removable plug and extending through and past the open end of the cylindrical body, such that upon a force being exerted upon the gripping strip, the partially removable 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.
