Arrived on site client stated her kitchen sink was backing up and she had a crack in a pipe below the kitchen sink. Upon inspection client had a crack on one of the nuts and we also noticed the basket strainer was old and rotting away. Clients kitchen line in the basement was slightly bellied. Today we replaced the basket strainer, 3/4 dishwasher tailpiece, and trap underneath as well as hydrojetting the kitchen line and strapping it in the basement. Tested for leaks under the sink and tested for kitchen sink flow. There are no leaks and the kitchen sink is now draining as it should.
