The short answer
A sewer smell often points to a dry trap, a vent issue, or a drain problem, and a smell plus backups points to a main line issue. In Goodlettsville homes, from older ranch homes to newer subdivisions like Twelve Stones Crossing and Copper Creek, the cause is often simpler than it first looks, so start with the easy checks, then call if the problem stays.
The short answer
Every drain has a trap that holds water to block sewer gas. If a trap dries out in a rarely used bathroom or floor drain, sewer gas can enter the room. A vent problem can also pull trap water out or fail to vent gas properly. A smell that comes with backups, gurgling, or several drains acting up at once points further down, toward a main line, and that needs prompt attention.
Checks in order
Run water in rarely used drains to refill traps, check whether the smell is in one room or throughout the home, and note whether it appears when another fixture drains. One room plus a dry trap is often a simple fix. A smell throughout the home, or a smell plus backups, is not a simple trap fix and should be diagnosed on site.
When to call right away
Call right away if the smell is strong, if sewage is backing up, if several drains are affected, or if anyone feels unwell in the affected area and you suspect gas exposure. Ventilate the area if you can do so safely, stop using water if backups are present, and call for help.
