4 Signs You May Have a Sewer System Problem
Do you hear gurgling sounds in your drains or smell foul odors from them? You could have a system issue. Learn the signs of major sewer system problems here.

Maintaining a healthy sewer system is vital for keeping your property functional and odor-free. Whether you’re a homeowner or property manager, ignoring sewer issues can lead to costly repairs and even health hazards.
Identifying early symptoms of system issues allows you to take prompt action, ensuring minor complications don’t become major emergencies. In this guide, we’ll cover the common signs to look out for that show you may have a sewer system problem.
Sign #1: Slow Draining Sinks and Tubs
One of the most common signs of a system issue is slow drainage in your sinks, showers, or tubs. If water takes unusually long to drain, it could signal a blockage in your sewer line.
To identify the problem, pay attention to how multiple fixtures behave. If just one drain is slow, the blockage may be local to that specific pipe. However, if multiple sinks, tubs, or toilets are slow to drain simultaneously, it’s likely a serious clog in your main sewer line.
Sign #2: Gurgling Sounds
If your drains or toilets are emitting an unusual gurgling or bubbling sound, it could be a sign of a partial blockage in the sewer lines. The trapped air forces its way through the water as it drains, creating a gurgling sound.
Gurgling noises could indicate anything from a minor clog to a damaged sewer vent. If these sounds persist, consult an expert, as air pressure issues may cause more significant problems with your sewer line.
Sign #3: Foul Odors
Another clear sign you may have a sewer system problem is the presence of foul odors on the property. These smells typically come from sewage gases like methane or hydrogen sulfide escaping from compromised pipes, clogs, or broken seals.
Inspect where the smells are strongest. If they’re overwhelming, it could be due to a crack or blockage of the sewer line. Persistent odors will likely require professional intervention to identify the exact source and fix the issue.
Sign #4: Sewage Backup
Sewage backups are among the most serious and unmistakable signs of a sewer system problem. If wastewater begins flowing back into your sinks, toilets, or tubs, it’s a clear indication of a severe blockage or damage in your sewer line.
If a backup occurs, avoid using any water in your home to prevent further flooding and contamination. Contact a professional plumber immediately to inspect and resolve the issue.
How To Prevent Future Sewer Problems
The best way to address these issues is to stop them from growing into significant problems with preventative maintenance and cleaning. Schedule routine inspections of the system to assess the stability and health of the system regularly.
Robotic cameras improve accuracy in sewer system assessments with high-resolution visuals inside the structure to identify blockages and structural issues. Also, if you live in an area with older trees, check your sewer lines for potential root intrusion, as early detection allows for targeted solutions like root removal.
Don’t Wait for a Sewer Emergency
Spotting sewer system issues early will save you time, money, and stress. Watch for the clear signs of major system issues and address them immediately to avoid major problems. With routine inspections and preventative maintenance, you can ensure your property’s sewer system is problem-free for years to come.
