Signs It’s Time to Replace Your Sewer Line

July 11, 2025

Your home’s sewer line is an essential component of your plumbing system, responsible for carrying waste away efficiently. However, like any other part of your home, sewer lines deteriorate over time. Ignoring early warning signs can lead to costly repairs, property damage, and even health hazards. Here are some telltale signs that indicate it might be time for your sewer line replacement.

1. Frequent Backups and Clogs

If you’re experiencing constant drain clogs, even after professional cleaning, your sewer line could be compromised. Tree roots, corrosion, or collapsed pipes can cause persistent blockages that simple drain cleaning won’t fix. Multiple backed-up drains throughout your home often point to a failing sewer line.

2. Slow Drains Throughout Your Home

A single slow drain might be an isolated issue, but when multiple drains are sluggish, it may indicate a problem with the main sewer line. This could be due to debris buildup, tree root intrusion, or pipe damage that prevents wastewater from flowing freely.

3. Unpleasant Odors

Sewer gases should remain contained within your plumbing system. If you notice foul smells coming from your drains, yard, or basement, it could mean your sewer line is cracked or leaking. Ignoring this issue can pose serious health risks to your household.

4. Soggy Patches in Your Yard

A damaged sewer line can leak water into your yard, leading to unusually green or soggy patches of grass. If you notice standing water or lush grass in one area despite dry weather, your sewer line may be leaking and in need of replacement.

5. Foundation Cracks or Sinkholes

A leaking sewer line can cause soil erosion beneath your home, leading to foundation cracks or even sinkholes. If you notice new cracks in your walls or floors, or if parts of your yard are sinking, it’s crucial to have your sewer line inspected immediately.

6. Pest Infestation

Rodents and insects are attracted to broken sewer lines. If you suddenly have an increase in pests like cockroaches, flies, or rats in and around your home, your sewer line may be compromised, providing an easy entry point for these unwanted visitors.

7. Higher Water Bills

If your water bill has unexpectedly increased without any changes in usage, it could be due to an undetected sewer line leak. Leaking water can waste gallons daily and indicate that your sewer system needs urgent attention.
