A plumbing testing device (10) has a pair of aligned and closed pipe sections (12 and 14) with open sides facing in opposite directions. The plumbing testing device (10) is longitudinally collapsible to facilitate removal from between pipe ends (19 and 20). The pipe sections (12 and 14) each have a port (32, 35), a transparent hose (38) connects the ports to one another, and a valve (30) controls the flow of water between the pipe sections (12 and 14) through the hose (38).
