Telltale signs
What the symptoms can tell you
Slow sinks, tubs that will not empty and toilets that gurgle after flushing may seem like minor frustrations, but they often point to something more serious. One slow fixture usually involves its own branch line, while several fixtures acting up together can point further down the system.
Odors creeping up from drains can signal decaying buildup or a sewer line issue, and water collecting around a floor drain can mean the line is backing up. Ignoring these signs tends to make them worse, so report them early.
