Customer kitchen sink was slow draining said he had a got cable it and then it backed up in three weeks so I gave him my option to Hydro jet. I ran the Hydro Jetter and ran the cable to remove grease. It was a ton of grease that was caked up, but after running both machines I was able to get The water moving and after testing the drain was draining perfectly with no leaks or backups that the customer know that the pipe underneath the sink was not up to code and I will get that fixed to help drain issues on right side , told the customer of the back up again just to give us a call more than likely it will be grease
