The answer to 'sewer repair slow draining' is that a slow draining sewer is often caused by a partial blockage or buildup in the main sewer line. This can be due to things like tree roots, debris, or a broken pipe. Symptoms include slow draining sinks, tubs, and toilets, as well as gurgling sounds coming from the plumbing.
In many cases, you can try to clear the blockage yourself using a plunger, auger, or chemical drain cleaner. However, if the problem persists or keeps recurring, it's best to call in a professional plumber. They have the tools and expertise to properly diagnose and fix the underlying issue, whether it's a full sewer line replacement or just a simple clog removal.
