Customer had gurgling in the sink for the kitchen. I ran my Hydro Jetter down the line to blast the grease that was in there. Didn’t have any blowback at all. It was one spot that I was stuck at, but then I was able to blast through after testing. The sink is draining perfectly around the water downstairs as well to make sure it didn’t move down to be locked up I couldn’t run the Hydro Jetter downstairs didn’t have a way to get a water source , water hose was not long enough to reach and it was nothing but a hot water heater nearby. The closest sink had to be 60 feet so didn’t have any access to get water from a stop from a sink. Camera is coming out tomorrow to run the camera down to clean out downstairs and if it is any remaining grease, we will come back and blow out the rest. Also, when I was hooking the water back up for the sink, the cold water stopped valve didn’t open back up so now I’m in the kitchen sink and only have hot water and no cold water. I’m scheduling for a service
