Stop Sewer Backups When Toilet Gurgling Starts

Cost Savings

Checklist Tasks

• Check all lower-level drains for slow flow or bubbling to spot shared blockages.
• Remove toilet tank lid and listen for bubbling during flushes; note vent problems.
• Inspect basement floor drains for standing water or sewage odors.
• Run water in nearby sinks; watch if toilet water rises, indicating pressure issues.
• Clear minor clogs using a drain snake at accessible cleanouts.
• Inspect exterior sewer cleanout caps for overflow or debris.
• Check yard and basement for wet spots or sewage odors indicating leaks.
• Delay washer and dishwasher use until the cause is found to prevent overload.
• Record when and how often gurgling occurs to help with diagnosis.
• Test roof vent stacks for blockages like leaves or debris.
• Flush one toilet at a time and check for any backflow as a blockage clue.
• Call a plumber if multiple fixtures are gurgling—this may signal a main line problem.
