Arrived on site client stated that a pipe broke underneath while Home Depot was installing her new dishwasher. Upon inspection client had a 3/4 brass dishwasher tailpiece that snapped. Replaced dishwasher tailpiece and connected dishwasher hose to the pipe. Tested for leaks with hot water and when testing the trap union started slowly leaking due to having to take everything apart. Took trap apart and put pipe dope on it and tested for leaks again with hot water. There are no leaks at this time at the dishwasher connection or the trap union.
