Fiber Installers Destroyed My Main Sewer Line: What Homeowners Need to Know

Finding out that your main sewer line has been damaged during utility installation can be one of the most stressful experiences for a homeowner. In many neighborhoods, new fiber optic internet lines are being buried underground to improve connectivity. Unfortunately, when contractors dig too close to existing infrastructure, accidents happen — and sometimes sewer lines are the unintended victims.

How Sewer Lines Get Damaged During Fiber Installation

Fiber installers typically use trenching or directional boring to run cables underground. While this method is usually safe, problems occur when contractors:

1. Fail to properly locate underground utilities – Sewer lines, water lines, and electrical conduits must be clearly marked before digging.

2. Work too quickly without precision – Rushing the installation process can lead to cutting through pipes.

3. Use heavy machinery in tight spaces – This increases the risk of accidental strikes on existing infrastructure.

Signs Your Sewer Line May Have Been Damaged

If you suspect your sewer line was hit during a fiber installation, watch out for these signs:

• Slow drains or frequent clogs throughout the home.

• Gurgling sounds in toilets or sinks.

• Sewage odors inside or outside the house.

• Water pooling in your yard, especially near where digging occurred.

• Visible pipe damage, like in the photo example.

What To Do If Your Sewer Line Was Damaged

1. Document Everything

   • Take clear photos and videos of the damaged pipe, the excavation site, and any related property damage.

2. Contact the Fiber Installation Company

   • Report the issue immediately. Most companies are insured and legally responsible for repairing utility strikes.

3. Call a Licensed Plumber

   • A professional plumber can assess the extent of the damage, provide an inspection (often with a sewer camera), and recommend repair options.

4. Avoid DIY Sewer Repairs

   • Unlike small leaks, sewer line repairs require specialized tools and proper sealing to prevent contamination and future breaks.

5. File a Claim If Needed

   • If the installation company denies responsibility, you may need to involve your homeowner’s insurance or pursue compensation.

Repair Options for a Damaged Sewer Line

Depending on the severity of the damage, plumbers typically recommend one of these solutions:

• Pipe Section Replacement – Cutting out the broken piece and replacing it with new PVC or ABS pipe.

• Pipe Lining (CIPP) – Inserting a resin-coated liner inside the damaged pipe to create a new, seamless interior.

• Pipe Bursting – Breaking apart the old pipe and pulling a new one through in its place.

The right method depends on the location, length of damage, and soil conditions.

Preventing Future Utility Strikes

While you can’t control how contractors work, you can take proactive steps:

• Request a utility locate before any digging on your property.

• Mark the path of your sewer line if known.

• Be present during installations and ask questions about digging depth and safety.

Final Thoughts

A damaged sewer line caused by fiber installers is frustrating, but it’s not the end of the world. With the right documentation, communication, and professional help, you can get the line repaired and costs covered. The key is acting quickly to prevent sewage backups and property damage.

If you’ve recently had fiber installed and notice plumbing issues, don’t ignore them. Call a plumber, get an inspection, and protect your home before the problem escalates.
