A sewer line backup is one of the most stressful plumbing emergencies a homeowner can face. Not only does it disrupt daily life, but it can also pose health hazards and cause significant property damage if left untreated. Knowing how to respond quickly (and when to call a professional plumber) can save you time, money, and a whole lot of frustration.
At Wilcox Plumbing, we’ve been helping homeowners in Justin, TX and the surrounding Denton County area deal with clogged sewer mains and emergency plumbing situations for decades. Here’s what you should do if you notice a sewer line backup in your home.
Signs of a Sewer Line Backup
Before you can act, it’s important to recognize the warning signs that your clogged sewer main is the culprit:
Multiple drains are clogged at once – If sinks, tubs, and toilets all start draining slowly, the issue may be deeper in your sewer line.
Gurgling sounds from drains or toilets – Air bubbles trapped in wastewater often signal a blockage.
Sewage odors – Foul smells coming from drains or your yard are a red flag.
Water backing up in unexpected places – For example, flushing the toilet causes water to rise in the shower.
If you notice any of these issues, don’t ignore them.. a minor blockage can turn into a full sewer backup fast.
Immediate Steps to Take During a Sewer Backup
If you’re experiencing a sewer line backup in your home, here are the steps to follow before calling an emergency plumber:
Stop using your plumbing fixtures
Don’t flush toilets, run faucets, or use appliances like dishwashers or washing machines. Every gallon of water adds to the backup.Shut off your water supply
If you can’t stop the flow, locate your home’s main water shutoff valve and turn it off to prevent further wastewater from entering your sewer line.Avoid using chemical drain cleaners
Over-the-counter drain cleaners are not effective on main sewer line clogs and can damage your pipes.Check your cleanout line if accessible
Some homes have a cleanout (a capped pipe usually located outside). Opening it may relieve pressure and allow some wastewater to flow outside rather than back into your home.Protect your health and property
Keep children and pets away from the affected area. If sewage has entered your home, wear gloves and avoid direct contact to reduce health risks.
When to Call a Professional Plumber
While small drain clogs can sometimes be cleared with a plunger, a clogged sewer main requires professional attention. Call an emergency plumbing service if:
Multiple drains are backed up at the same time
Sewage water is present inside your home
You’ve tried basic steps but the problem persists
You notice sewage pooling in your yard or near your home’s foundation
Professional plumbers, like the team at Wilcox Plumbing, have specialized tools such as sewer cameras and hydro-jetting equipment to identify and remove stubborn blockages safely and effectively.
Preventing Future Sewer Line Backups
The best way to deal with a sewer line backup is to prevent it from happening in the first place. Here are some tips:
Don’t flush non-flushables – Items like wipes, paper towels, and feminine hygiene products can cause major blockages.
Dispose of grease properly – Grease hardens inside pipes and contributes to clogs. Always throw cooled grease in the trash.
Schedule regular plumbing maintenance – Routine inspections can identify root intrusion, cracks, or buildup before they become an emergency.
Install a backwater prevention valve – This device helps stop sewage from backing up into your home during heavy rains or clogs.
