Plumbing system test fitting

摘要

A plumbing test fitting for insertion in a plumbing drain or pressure fluid distribution system includes a body with two spaced-apart lateral ports formed thereon and opening into a central bore of the body. One of the ports is adapted for receiving a hose bib for connection to a source of test fluid and the other port is provided for withdrawing a flexible diaphragm from the interior of the body with a pull member extending through the other port. The flexible diaphragm is retained in the body during a pressure or leakage test of the plumbing system and is removed after completion of the test by tearing the diaphragm away from a supporting rim part. The flexible diaphragm is foldable to be withdrawn through the other port which may be of a diameter smaller than the normal unfolded diameter of the flexible diaphragm.
