Most homeowners don’t think about their sewer line until there’s a problem. Unfortunately, when trouble strikes, it often means a messy backup or costly repairs. As Chicagoland’s trusted plumbing experts since 1972, MR Plumbing Heating Air Electrical has answered thousands of homeowner questions about sewer lines. Below, we’ve broken down the six most common concerns we hear—and what you need to know to protect your home.
1. How long does a sewer line last?
The lifespan of a sewer line depends on the pipe material, soil conditions, tree proximity, and maintenance history. On average:
- Clay pipes: 50–60 years
- Cast iron pipes: 75–100 years (but prone to corrosion)
- PVC pipes: Can last 100+ years if properly installed
If your home is over 40 years old—or you’re experiencing frequent clogs or slow drains—it may be time for a professional sewer line inspection. Even newer homes can connect to older municipal lines that are failing.
2. Who is responsible for repairing a damaged sewer line?
In most Chicagoland municipalities, homeowners are responsible for the sewer line from the house to the connection at the city sewer main. That means if the line under your yard, driveway, or sidewalk fails, you—not the city—are responsible for the repair.
3. Does homeowner’s insurance cover sewer line repairs?
Standard homeowner’s insurance usually does not cover sewer line replacement due to age, corrosion, or tree root intrusion. However:
- Some policies allow you to add a sewer and drain endorsement that covers damage from backups.
- A few insurance companies offer separate sewer line coverage for repairs or replacement.
It’s a good idea to call your insurance provider and ask specifically about sewer coverage before you have a problem.
4. What causes sewer line damage?
The leading causes of sewer line problems we see in the Chicagoland area include:
- Tree root intrusion: Roots naturally seek water and can penetrate joints in older clay or cast iron pipes.
- Pipe corrosion or deterioration: Especially in older cast iron lines.
- Ground shifting or settling: Freeze-thaw cycles can shift soil and damage pipes.
- Accidental damage: From nearby digging or construction.
- Grease, wipes, and debris: Everyday misuse that accelerates clogs and pipe failure.
5. How can I prevent sewer line problems?
While you can’t stop every issue, there are steps you can take to dramatically reduce your risk:
- Schedule a video camera inspection every few years to catch small cracks, bulges, or root intrusion early.
- Avoid flushing wipes—even if labeled “flushable.”
- Dispose of grease and oil in the trash, not the drain.
- Be mindful of landscaping: avoid planting large trees or shrubs directly above your sewer line.
Regular maintenance costs a fraction of a full sewer replacement—and can prevent raw sewage backups inside your home.
6. My sewer line is damaged—what are my options?
Years ago, the only way to fix a broken sewer pipe was to dig a trench through your yard. Today, homeowners have more options:
- Traditional sewer replacement: Excavating and replacing the damaged section of pipe. Necessary in severe cases.
- Trenchless sewer repair (pipe relining): A no-dig solution where a durable liner is inserted inside the existing pipe. This restores flow and prevents future leaks without tearing up your yard, driveway, or landscaping.
- Hydro jetting and cleaning: In cases of root intrusion or heavy buildup, high-pressure jetting can restore flow before more advanced repairs are needed.
