The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.
