If you are experiencing any of these symptoms of a damaged sewer line, you should have a sewer inspection done by a qualified professional such as Pipelining Technologies, Inc. If it is the vent pipe you can hire a plumber to unblock the vent pipe if you don't want to do it yourself. My kitchen sink has started to back up. A sewer cleanout plug is made of either cast-iron, plastic (PVC) screwed down into the cleanout pipe.
