Abstract
For pressure testing a drain and vent piping system communicating with a tub opening having an anchoring structure a plug has a central, axially extending aperture therethrough. The plug has a resilient, compressible portion and is provided with inner and outer ends. An anchor is located at the inner end of the plug and extends axially beyond the inner end to engage with the anchoring structure and seal the tub opening. The test plug assembly also includes a threaded shaft that passes through the aperture in the plug and connects to the anchor. A manually operated threaded actuator is located at the outer end of the plug and is configured for threadingly engaging the shaft to draw the actuator towards the anchor and compress the compressible portion of the plug to block fluid flow through the bath tub opening and permit pressure testing of the drain and vent piping system. The manually operated threaded actuator can be rotated to disengage the actuator from the threaded shaft and permit the removal of the test plug assembly from the tub opening.
