6 Common Causes of Sewer Backups in Indianapolis & How to Fix Them

No homeowner wants to deal with a sewer backup—but unfortunately, they’re a fairly common issue in Indianapolis. Between aging infrastructure, heavy seasonal rains, and tree-lined neighborhoods, our local sewer systems face quite a few challenges.

Whether you’ve already experienced a backup or want to avoid one in the future, it’s helpful to understand what causes them, how to spot the signs, and what you can do to prevent costly damage.

 

Signs of a Sewer Backup

While it oftentimes feels like sewer backups happen out of the blue, there are a few warning signs you can look out for:

• Sounds from Drains: Gurgles, bubbles, or other such noises in toilets, sinks, or tubs can indicate a clog or blockage in your sewer system.
• Slow Moving Drains: If more than one drain in your home is moving slowly, there could be a problem deeper in your sewer system.
• Water Backup: Water coming back up through your drains only happens when there is an issue in your drain line.
• Sewage Smell: A strong sewage smell is often the first and most obvious sign that something is wrong with your system.
• Changes in Yard: Unusually lush patches of grass, soggy areas, or sinkholes can be signs that sewage or additional water is leaking underground.

 

Common Causes of Sewer Backups

While they can cause major damage, sewer backups are often caused by simple issues that grow over time.

 

Municipal Sewer Issues

If there’s a problem with Indianapolis's sewer line—like an overflow or clog—it can cause sewage to back up into your home, even if your system is functioning properly. Unfortunately, this is out of your control. If you suspect a city sewer issue, contact the Indianapolis Department of Public Works.

 

Clogged or Blocked Pipes

Your sewer line and pipes are only so big. When food and other larger items are poured down the drain, you can create clogged or blocked pipes that create a backup in your sewer system.

 

Damaged Pipes

Cracked, corroded, or collapsed pipes can disrupt flow and lead to backups. This is especially common in older Indianapolis neighborhoods with aging sewer systems.

 

Tree Roots in Sewer Line

Tree roots are naturally drawn to moisture—so they often grow into sewer line cracks and joints. Once inside, they can expand, block flow, and create bigger cracks within your pipes.

 

Sewer System Age

Many homes in Indianapolis still rely on sewer lines that are decades old and made of less effective materials. Over time, these systems become more susceptible to corrosion, cracks, and collapse.

 

Heavy Rain

Excessive rainfall can overwhelm both private and municipal sewer systems. When this happens, stormwater can flood the sewer lines and force sewage back into your home.

 

Preventing Sewer Backups

While you can’t control the weather or the city’s sewer system, there are a few things you can do to prevent sewer backups in Indianapolis.

• Watch What Goes Down the Drain: Grease, fibrous foods, and non-flushable materials can create disastrous clogs and blocks. Be sure to use a strainer and be mindful of what goes down the drain.
• Schedule Regular Maintenance: When your system is properly maintained and inspected, you can prevent or catch many of these common causes of sewer backups before they become major and costly issues.
• Update Old Sewer Lines: If your home is more than 40 years old and still has its original sewer lines, it may be time for an upgrade. Contact a plumbing professional to evaluate the state of your system and update any outdated elements.
• Maintain Your Yard: Again, trees can wreak havoc on your sewer system. Avoid planting any near sewer lines, and keep an eye out for signs of root intrusion or soft spots in your lawn.

 

Sewer backups can be messy, stressful, and expensive—but they’re often preventable. Understanding the common causes and working with a trusted local plumber can go a long way in keeping your home safe and running efficiently.
