Arrived on site client stated their kitchen sink was backing up. Upon arrival we noticed the water was at a complete stop and not draining at all. Left options to remove fernco and repipe the small section of pvc but client would like to just hydro jet for today. Snaked and hydro jetted the kitchen sink multiple times and when done we tested with hot water. Filled and dumped the sink with hot water multiple times and the kitchen sink is now draining as it should.
