How to dissolve floating fats in home sewer line?
Hello. In the past 3 months, I had 3 clogs in the home sewer line. Had it snaked twice and jetted once. Long story short, a section of the 6" clay pipe was cracked and was replace with pvc. Once the broken line was replaced, I had the line video inspected. Found that there is a back pitch in the home sewer line as it gets close to the city sewer main. But the most disturbing was the amounts of fats or grease floating in the pipe. Attach is the pic from the video cam. i tried flushing it with the hot water in hopes that it would melt but that did not work. Is there any chemicals available or recommendations that would be able to dissolve the floating fats?
Thanks for the help.
