What Causes Sewer Backups in Homes?

Last updated October 25, 2026

The short answer

Tree Roots and Pipe Damage

Tree roots naturally seek moisture and can grow into tiny cracks or joints in your sewer line. Over time, roots expand and create a blockage that traps waste and water. The pipe may also collapse or shift due to ground movement, which narrows the passage.

Older homes in areas with mature trees are more prone to this issue. You might notice slow drains, gurgling sounds, or water pooling in your yard. A sewer camera inspection by the pros can reveal root intrusion and pipe condition.

If you suspect root damage, avoid flushing anything that could worsen the clog. Keep an eye on your yard for wet spots or unusual plant growth, which can indicate a leak.

  • Slow draining sinks or tubs
  • Gurgling noises from toilets
  • Water backing up into showers
  • Sewage odor around drains
  • Wet or soft spots in your yard
  • Frequent clogs in one area

Flushing the Wrong Items

Many sewer blockages start with items that don't break down in water. Wipes, paper towels, feminine products, and diaper wipes can clump together and catch on pipe walls. Even items labeled flushable often cause trouble.

Cooking grease is another major culprit. When poured down the sink, grease cools and hardens inside pipes, creating a sticky layer that catches debris. Over time, this buildup narrows the pipe and eventually blocks flow.

The fix is simple: only flush human waste and toilet paper. Dispose of grease in a container and throw it in the trash. Remind everyone in the home about these rules.

  • Baby wipes and cleaning wipes
  • Paper towels and napkins
  • Feminine hygiene products
  • Cooking oil and grease
  • Coffee grounds and eggshells
  • Household chemicals and paint

Heavy Rain and Flooding

In a humid subtropical climate, heavy rain can overwhelm the municipal sewer system. Stormwater may enter the same pipes that carry household waste, exceeding capacity. When the system is full, water has nowhere to go but back up into your drains.

During heavy rain, limit water use to reduce strain on the system. Avoid running the dishwasher or washing machine until the storm passes.

Blocked Main Sewer Line

The problem isn't always in your home's pipes. The main sewer line that runs under the street can also get blocked, often due to debris, silt, or roots from nearby trees. When the main line backs up, it affects multiple homes on the block.

You might notice sewage rising from your toilet or floor drain even when you haven't used water. If neighbors have similar issues, the problem is likely in the municipal line. Contact your local utility department to report it.

If you live in Euless, keep your home's cleanout access point clear so the pros can reach it easily. Regular maintenance of your private line can help prevent backups.

What to Do After a Backup

A sewage backup is a health hazard because raw waste contains bacteria and viruses. Avoid contact with the water and keep children and pets away. Turn off the water supply to your home to stop more flow, and shut off the affected fixtures.

Do not use chemical drain cleaners, as they can create harmful fumes when mixed with sewage. The pros can remove standing water, sanitize the area, and dry out affected materials. This process usually involves extraction, drying, and disinfecting.

Document the damage with photos for your insurance records. Policies vary, and your insurer decides what is covered. Check your policy to understand your coverage for sewage backups.

Frequently asked questions

Can a sewer backup cause mold?

Yes, sewage water is damp and can soak into drywall, wood, and carpet. If not dried within 48 hours, mold can start growing. The pros use drying equipment to remove moisture and may test for mold after cleanup.

How can a homeowner prevent a sewer backup?

Avoid flushing anything except toilet paper, and never pour grease down the drain. Have a plumber inspect your pipes for roots. Consider installing a backwater valve, which prevents water from flowing back into your home during heavy rain.

Is a sewer backup covered by insurance?

Some policies include coverage for sewer backups, but many require a separate rider. Check your policy documents or ask your insurance company. Policies vary, and your insurer decides what is covered. If you have coverage, document all damage and keep receipts.
