The answer to 'sewer line not working' is that there are several common causes, including a blockage, a broken or cracked pipe, tree root intrusion, or a problem with the septic system. Symptoms may include slow draining sinks, gurgling sounds, sewage backups, and foul odors.
For minor clogs, you can try using a plunger or a drain snake to clear the blockage. However, if the problem persists or you suspect a more serious issue, it's best to call a professional plumber. They can diagnose the problem, provide an estimate, and perform the necessary repairs or replacement. Trying to fix a complex sewer line issue on your own can lead to further damage and costly repairs, so it's usually best to leave it to the experts.
