A sewer backup can go from an unpleasant plumbing problem to a serious household emergency very quickly. If sewage begins coming up through a shower, bathtub, toilet or floor drain, knowing what to do next can help limit additional damage.
The first and most important step is to stop using water throughout the house. Do not flush toilets, run faucets, take showers or use appliances such as the washing machine or dishwasher. When the main sewer line is blocked, additional water has nowhere to go and may push more wastewater back into the home.
Keep children and pets away from the affected area and avoid contact with contaminated water. If the backup is near electrical outlets or appliances, stay out of the area and do not attempt to shut off power unless the breaker can be reached safely.
Signs of a Main Sewer Line Backup
A single slow sink may indicate an isolated clog. However, the following symptoms often point to a larger sewer-line problem:
-
Multiple drains backing up simultaneously
-
Water rising in a shower when a toilet is flushed
-
Toilets bubbling or making gurgling sounds
-
Sewage appearing in the lowest drain in the home
-
Wastewater coming from an exterior sewer cleanout
-
Persistent sewer odors inside the house
-
Drain problems that return after being cleared
Main sewer backups can be caused by grease and debris buildup, tree-root intrusion, deteriorated cast-iron pipes, separated joints, improper slope or a partially collapsed sewer line.
Professional drain-cleaning equipment may restore flow, but recurring backups often require a sewer-camera inspection to identify the underlying cause. Clearing a blockage without addressing a damaged pipe may provide only temporary relief.
North Texas soil can also place additional pressure on buried plumbing lines. As the soil expands and contracts, older sewer pipes may shift, crack or separate. Homes with mature trees may face additional problems when roots enter small openings in the line.
