Customer’s kitchen sink was gurgling and backing up on both sides upon arrival, after diagnosing I determine that it had to be some grease or buildup in the line so I ended up running my cable and after testing I was able to get the water flowing perfectly again. I did have grease specs on my cable, but after thoroughly testing, the drain is working normally let the customer know if they did have issues again we could try to run the cable again or go to the next step running a Hydro Jetter
