Clear kitchen sink Customer was experiencing blockage in kitchen sink affecting both kitchen sink and laundry drain. While running water in kitchen sink during inspection I noticed water backing up. I tested all fixtures in home to ensure each fixture had proper drain flow. I ran k45 cable machine to clear blockage. After running cable, I tested kitchen sink to ensure we had proper flow and I proceeded to test washing machine to ensure it had proper drain flow. After running tests we were successful and had no leaks.
