How do you know if you have a sewer line problem?

Your home’s sewer line plays a critical role in keeping your plumbing system functioning properly. It carries wastewater away from your sinks, tubs, toilets, and appliances to the main sewer. When something goes wrong with that line, it can quickly turn into a major (and messy) issue. Knowing how to spot the warning signs early can save you thousands in repairs and prevent significant property damage.

At Frank’s Mr. Plumber, we help homeowners across Tonawanda, Orchard Park, and the Buffalo metro area identify and repair sewer line problems fast. Here are some telltale signs to watch out for.

Slow Drains Throughout the House

If one drain is running slow, the issue might be localized. But if you notice multiple drains—like your shower, kitchen sink, and toilet—all draining sluggishly, the problem is likely deeper in your plumbing system. This is often a sign of a blockage in your main sewer line.

Gurgling Sounds or Air Bubbles in Toilets

Unusual noises like gurgling toilets or air bubbles coming up after flushing could mean air is trapped due to a clog or break in your sewer line. These sounds might not seem serious at first, but they can indicate pressure problems that need immediate attention.

Frequent Backups or Overflows

A sewage backup in the basement or first-floor drain is one of the most obvious signs of a serious issue. If you’re experiencing recurring backups, especially during heavy water usage, there’s a good chance your main sewer line is blocked, broken, or damaged.

Bad Odors Inside or Outside

Sewer gases should never leak into your home or yard. If you smell rotten eggs or a strong sewage odor coming from your drains, basement, or lawn, it may be due to a crack or leak in your sewer line. This is not only unpleasant but also a potential health hazard.

Soggy Spots or Sinkholes in the Yard

Notice any unusually wet patches, soft ground, or even sinkholes forming in your yard? These could be signs of a leaking underground sewer pipe. A broken line can allow water and waste to seep into the soil, which over time can erode the ground above it.

Sudden Pest or Rodent Problems

A cracked or broken sewer line can attract rodents and insects that are drawn to the moisture and smell. If you’re seeing more bugs or rodents around your property than usual, your sewer system could be to blame.

What Causes Sewer Line Problems?

There are several reasons your sewer line might be acting up:



• Tree Root Intrusion: Roots seek moisture and can grow into pipes
• Aging Pipes: Older homes may have corroded or brittle pipes
• Poor Installation or Soil Shifting: Can cause pipes to collapse or disconnect
• Grease, Debris, or Non-Flushables: Everyday clogs that build over time

Why Professional Diagnosis Matters

The only way to know for sure what’s going on beneath the surface is with a sewer camera inspection. At Frank’s Mr. Plumber, we use advanced diagnostic tools to pinpoint the exact location and cause of the problem—without tearing up your yard. This allows us to recommend the most cost-effective repair or replacement option.
