The most common problems that affect your Sewer Line

Sewer line issues are inevitable in any home. Here are some of the common issues that you may come across:

  • A leak, break, or a stoppage in a water line within the main foundation
  • Stoppages of the mainline and lateral drain lines from the main access point
  • Pools of septic waste
  • Sewage backup or blockage
  • Pipe corrosion or age deterioration
  • Mold, foul odors, pests, and slow drains

How to Maintain a Sewer Line

In most cases, sewer line problems are caused by human mistakes or poor maintenance. As a homeowner, you can follow these tips to ensure your sewer line does not clog or fall into disrepair.


Here are a few simple and quick tips for maintaining your sewer line:

  • You must not flush non-biodegradable objects or cooking oils in the sewage.
  • Don’t reach out to your local contractor beforehand
  • Take precautions to ensure tree roots don’t come in contact with the sewer line.
  • You should check your plumbing system regularly.
  • You shouldn’t pour grease down the drain.
  • You must keep paper products out of your pipes.
  • You can consider replacing your old pipes with new PVC pipes.
  • You should install a backwater prevention valve.

It is advisable to inspect the plumbing system during your home inspections. Dysfunctions in the pipelines such as corroded pipes, or faulty valves can result in significant damage to the sewer line. Hence, it is always a good idea to assess the situation beforehand and take precautionary measures immediately.

How Does a Sewer Line Warranty Work?

When you purchase a home warranty plan that covers the sewer line, there may be a waiting period of 30 days before the coverage kicks in. After that, you can contact your service provider whenever you face some issues with the sewer line. Home warranty companies assign a licensed technician to diagnose the problem and conduct repairs.

Thereafter, the company makes a decision regarding repair or replacement and offers coverage accordingly. You also have to pay a service fee for each service request which is also known as a deductible, and it generally ranges between $60 to $150.

What does Sewer Lines Coverage Include?

Most of the home warranty companies provide coverage for sewer line problems. The following are some of the common sewer line issues that are covered by a home warranty:


Your home warranty can cover the waterline leaks, breaks, and stoppages within the main foundation.


The company generally provides service for mainline and lateral drain line blockages within 100 feet of the main access point.


Even pipes that are hidden behind walls, ceilings or floors in a rough condition can be covered.


A company’s basic protection plan may not include every coverage option of your choice. You can look and add additional items to existing plans for an extra fee. For example, septic tank pumping and septic systems include sewage ejector pumps, jet pumps, and aerobic pumps.

However, there are also a few exceptions to the coverage of sewer lines under a home warranty. The following are some to keep in mind, as the service contracts may not cover:

  • Stoppages and clogs in the drain and sewer lines more than 100 feet from the access point
  • Broken lines, leaks, or stoppages outside the main foundation or clogs due to roots.
  • Pipe damage caused by sediment, rust, or corrosion
  • Disposal of septic tank waste or chemical cleaning

Your plan may have other limitations too. You will find them in the service contract or guide of your home warranty. Hence, make sure you read your contract carefully to know what is covered and what isn’t.

Cost of Repairing and Replacement of the Sewer Lines

The average repair and replacement cost of a sewer line can be around $200- $1500, depending on the type of issue and the length or width of the sewer pipe. It also depends on the pipes’ location and whether it’s PVC, Cast Iron, Lead, or Orangeburg Pipes.

Sewer Line Costs
Average Repair $2,250-$5,000
Average Replacement $50 to $250 per foot
Pipe-Under-Slab Repair $200-$450 per foot
Removing Tree Roots $100-$600
Labor $200 per hour
Traditional Sewer Method Replacement $7,500
Replace or Repair of Sewer Line in a Basement $3,000 to $5,000
Full Length of your Sewer Line Replacement $8,000 to $30,000
New Sewer Lining $26 and $107 per foot
Trenchless Sewer Line Repair $80 to $255 per linear foot

If the sewer line on your property has leaks, bursts, sewage water starts flowing into your home, damaging the floors, walls, and furniture. A single sewage incident can incur huge costs when it comes to replacing furniture, flooring, sheetrock, or more.

In such a situation, getting a home warranty can be a good deal. A home warranty offers various plans. The average monthly cost of a home warranty plan is around $25-$60. Apart from this, you will have to pay a deductible of $60-$150 to the service technician after the repair.

Is a Home Warranty Worth It For Sewer Lines?

A home warranty plan can help alleviate some of the financial burdens associated with the unexpected expense of sewer line issues. It offers peace of mind when the sewer line breaks or has leakage and requires repair or replacement. However, the company plan may not cover every problem. So, we recommend reading the contract very carefully before you sign it.
