An attempt was made to clear a blockage in the kitchen sink drain. The drain line was snaked from the kitchen sink down to the 3-inch main drain, where a blockage was encountered that could not be cleared from the upstairs access point. A rubber Fernco coupling was then removed to gain additional access to the line, allowing the drain to be snaked from that location. The blockage was successfully cleared, and the kitchen sink was tested and is now draining properly. All components were reinstalled and secured, and the drain system is functioning as it should.
