Arrived. Customer explained that her kitchen line was backing up into her floor drain and running water. Had her run kitchen sink and watch water come up to the floor drain leading me to believe the clog was in between the kitchen line and the floor drain clean out. Took floor drain clean out cap off and ran line all the way through cleaning it thoroughly. Ran water while clearing line to make sure I knew when it was cleared. Did extensive testing in kitchen sink with no back ups occurring. Line is open and flowing
