Drain clean mop sink wheat ridge Ran Spartan 100 out to clear obstruction in prep area floor sink. I ran lots of hot water to test and working properly now, however there is another string of floor sinks near prep table in front of house that is separate which is backing up they did not want to have these cleared. I recommended to have grease interceptor pumped out, and have us come back to give an estimate on getting all four sinks and drain lines in kitchen area. I also recommended to have changes in triple sink areas replaced as well as Cleaning out strainers and floor sinks. Also suggest replacing atmospheric vacuum breaker at mop sink area. Thank you
