Arrived on site client stated that their kitchen sink was backed up. Upon inspection client also had a leak that he attempted to repair under the kitchen sink himself. Client stated they also attempted to snake it themselves. Gave options to hydro jet the sink drain and to fix the drainage underneath the sink. Hydro jetted and snaked the kitchen multiple times and when done we repipe the kitchen drainage and tested for leaks and sink drain flow. There are no leaks at this time and the sink is draining as it should. Cause of clog appeared to be a bad grease blockage.
