How Can You Take Care of Your Sewer Lines?

To ensure that you get home warranty coverage should your sewer lines fail, you need to take care of the system. Home warranties cover sewer repairs only if they are due to normal wear and tear, so preventive maintenance is key to getting the most out of your home warranty plan. 

Take care of your sewer and water lines by following these best practices:

  • Don’t put paper products down the drain. Paper products such as feminine hygiene products, paper towels, wet wipes, and disposable diapers can clog your drains. Unlike toilet paper, designed to deteriorate, these products can lead to blockages.
  • Don’t pour grease down the drain. When grease hardens, it can cause blockages in the drain. Instead of pouring hot, liquid grease down the drain, pour it into a heat-resistant container and throw it away when it has cooled and hardened.
  • Be careful about what goes down your garbage disposal. Your garbage disposal can take care of most food items, but avoid putting anything too hard down your disposal, such as animal bones and dense vegetables.
  • Monitor and manage tree roots. Tree roots can enter your sewer and water lines if not properly maintained. Monitor your tree roots and hire a professional to prune them if they grow too much.
  • Install plastic pipes. PVC pipes are much more resistant to tree roots and damage, so replace old pipes with plastic piping.
  • Install a backwater prevention valve. Have a professional plumber install a backwater prevention valve to prevent sewer water from coming into your home.

How Do Sewer Line Warranties Work?

Sewer line warranties work the same as any home warranty: As soon as you notice a problem with your sewer line, call your home warranty provider and submit a claim online. 

Identifying a sewer line leak or blockage is key because you want to make a claim immediately. To identify a problem with your sewer service line, look for these signs:

  • Clogs and backups that occur in increasing frequency
  • Cracked concrete in your foundation
  • Signs or sightings of pests, such as cockroaches or rodents
  • Slow-draining sinks, showers, and toilets
  • Stagnant water in your yard

Once you suspect there is something wrong with your sewer line, you need to contact your home warranty provider by following the steps outlined below:

  1. Call or submit an online claim with your home warranty provider.
  2. Your warranty provider will respond within 24 to 48 hours.
  3. Your warranty provider will approve your claim.
  4. Your warranty provider will send out requests to your local service technicians
  5. The service technician will accept the request and come to your home and assess the damage.
  6. The service technician will diagnose the sewer system’s failure and recommend action.
  7. A repair appointment will be scheduled to fix or replace your sewer line.
  8. You will pay the service call fee and any elements not covered by your warranty plan.

What Does a Sewer Line Warranty Cover?

Sewer line warranty coverage is meant to cover the cost of repairing clogs, leaks, and breaks caused by normal wear and tear of your sewer and water lines. Most home warranty plans, such as those offered by Liberty Home Guard and Select Home Warranty, cover the major problems that can arise with your sewer line, but some limitations apply. 

Under most home warranty plans, a sewer line warranty covers:

  • Breaks, cracks, and leaks in your water pipes, either within or beneath the foundation
  • Blockages in your water lines, lateral lines, and sewer lines
  • Repairs or replacements of old pipes, valves, seals, and joints
  • Pipe damage due to rust, corrosion, or sediment (may vary by provider)

Exclusions and Limitations of Sewer Line Warranties

Each home warranty provider will have slightly different exclusions and limitations to their warranty coverage of your sewer line. Most providers have an annual coverage limit of $1,500 to $3,000 for sewer and water lines. On the other hand, American Home Shield has an unlimited coverage cap for plumbing systems.

The most common exclusions on your sewer line include the following:

  • Leak detection and testing
  • Pipes that have collapsed, cracked, or broken down due to freezing
  • Repairs that exceed the annual coverage limit
  • Septic tank draining and cleaning
  • Sewer line damages that extend beyond the specified length from the foundation or main sewer hook-ups
  • Tree root damage
  • Waste disposal

How Much Do Sewer Line Warranties Cost?

The total monthly cost of your home warranty can vary depending on the service fee you choose and the additional household items you add to your warranty plan. The average monthly cost of sewer line coverage ranges from $45 to $65 per month, but the national average is $50 per month for the most basic system plan that covers your sewer line. 

With most home warranty providers, sewer line coverage is included in your base rates, so you don’t have to worry about paying additional fees to cover your sewer line. However, if you have a septic tank instead of a shared sewer system, you may need to purchase additional coverage for your decentralized septic tank. On average, these additional costs are affordable at $10 or less per month.

Factors of Sewer Line Warranty Costs

Because base warranty plans cover sewer lines, the cost is based on the complete coverage of that plan. Your monthly cost is mostly determined by the following:

  • Number and type of systems and appliances included in the plan. More comprehensive plans tend to be more expensive. For example, appliance-only or systems-only plans are typically less expensive than combination plans.
  • Service call fee. The lower your service call fee, the higher your monthly premium, and vice versa. The service call fee is what you pay per claim, so you will have a higher monthly cost if you have a $75 service fee instead of a $125 service fee.
  • Add-on coverage. Add-on items are typically less than $15 per month, but your monthly cost can quickly add up if you add more than one. To keep costs down, only choose the add-ons you need, such as a septic tank if you have one on your property.

Is Sewer Line Warranty Coverage Worth It?

Because sewer lines aren’t always covered by homeowners insurance, a sewer line warranty may be worthwhile. If your sewer line backs up or leaks, it can cost up to $7,500 to repair. Given these high repair costs, paying as little as $600 per year for a home warranty is worth it for peace of mind.

Home warranties not only cover sewer lines and water service lines but provide protection plans for nearly every major appliance and system in your home. In addition, home warranties cover repair costs for normal wear and tear that aren’t covered by your home insurance policy.

What Should You Look For in a Sewer Line Warranty?

When looking for sewer line warranty coverage, there are several factors that you should keep in mind. Your sewer line will often be covered under plumbing systems, but certain components of that sewer line may need to be added as extra coverage. In addition, your sewer line will be subject to exclusions, so carefully read your contract to determine the extent of coverage. 

As you explore sewer line warranty coverage, keep the following in mind:

  • Plumbing systems coverage
  • Mainline coverage
  • Exclusions and limitations

Plumbing Systems Coverage

Many home warranty companies offer plumbing systems coverage as part of their systems or combination plans, but this coverage can vary depending on the provider. 

If you want sewer line coverage, choose the home warranty provider that offers the most comprehensive coverage for your plumbing system, which may include the following:

  • Drain line clogs
  • Faucets, shower heads, and shower arms
  • Hose bibbs — both interior and exterior
  • Leaks or breakdowns of your water line, waste line (sewer line), gas line, and vent line
  • Toilet bowls, toilet tanks, flangers, wax seal rings, and tank assembly parts
  • Water heaters

Fixtures aren’t always included in plumbing system coverage but can be purchased as additional coverage. 

Mainline Coverage

The mainline can be covered by your home warranty and is often covered up to 100 feet from the main access point. Mainline damage is often a lot more expensive than sewer line and water line damage, but you should expect the same service fees.

Exclusions and Limitations

Some companies have lower coverage caps for plumbing systems than other home systems, such as heating and cooling. For example, Liberty Home Guard covers up to $2,000 for HVAC repairs, but up to $500 for plumbing and sewer line repairs.

This means that you may get less coverage and lower coverage caps as compared to other home systems, so look for the home warranty company that offers the most comprehensive coverage and highest coverage caps for your sewer line, like the unlimited systems coverage from AHS. Unlike your plumbing systems which are included in base home warranty plans, septic system warranty coverage is often extra. 

So, What is the Best Home Warranty for Sewer Lines?

Since every homeowner’s needs are different, the best home warranty for sewer lines is the one that best fits your needs. Every provider on our list offers excellent sewer line coverage. It all depends on how much you want to pay each month and what coverage you want.

If you want comprehensive coverage for your utility lines, you should choose a plan from American Home Shield or Choice Home Warranty, as these providers offer a high amount of coverage for plumbing lines. However, if you want more advanced coverage, you can purchase an additional utility line warranty from The Home Service Club that will provide just that.

FAQs About Sewer Line Warranty

Does homeowners insurance cover sewer line issues?

Unless you purchase specific coverage for your sewer lines, you likely won’t get sewer line protection from your home insurance. Some national home insurance providers may have sewer line insurance available, but you may need to add it to your plan at an additional cost.

Does homeowners insurance cover septic tanks?

Because septic tanks are commonly located outside the home’s main structure, septic tanks aren’t often covered by home insurance policies. You may be able to purchase a home insurance rider — i.e., additional coverage — that includes your septic tank, but even this won’t cover repair costs should your septic tank break down due to normal wear and tear as a home warranty would.

Does homeowners insurance cover tree roots in the sewer line?

Home insurance covers sudden damage from natural disasters, so it may not cover tree root damage. Tree root damage is a gradual process, which is why it is often not covered by home insurance plans. 

Methodology: How We Rank Home Warranty Companies

At Today’s Homeowner, we strive to bring you the most transparent, accurate information for your home improvement projects. Our home warranty company ratings emphasize what matters most to you — whether you’re looking for low-cost coverage, a hassle-free repair process, 24/7 assistance, or all of the above.

Our ratings are based on publicly available information about each company, secret shopping online and over the phone, customer-review analysis, and discussions with real estate professionals and repair contractors.

A company can earn a maximum of 100 points across six categories converted to a five-star scale. We researched more than 60 home warranty providers to develop the following formula:

methodology for evaluating home warranties for sewer lines
  • Plans and Coverage (24 points): A home warranty provider can earn the maximum point value in this category if it offers multiple robust plans that cover all basic systems and appliances and optional add-on coverage. We give bonus points to companies that cover uncommon items, such as electronics and roof leaks.
  • Affordability (22.5 points): When evaluating costs, we not only consider monthly plan prices, but we also take into account the cost of add-on coverage, service fees, and whether companies offer free cancellation periods or money-back guarantees. If a provider allows potential customers to view sample contracts before getting a quote, that transparency earns more points in this category.
  • Customer Experience (18.5 points): A home warranty company must give its customers ample support when they experience issues. We gauge overall support by looking at customer reviews and conducting homeowner surveys. We also go through the quotes process with each company and take meticulous notes about the friendliness of salespeople, how detailed each quote is, and how often the provider contacts us after giving a quote. 
  • Company Reputation (17.5 points): In this category, we look at a combination of customer reviews and reputable organizations such as the Better Business Bureau (BBB). We also consider the years of company experience, how satisfied its employees are, and whether it has been hit with any consumer rights violations or lawsuits. 
  • Claims Process (12.5 points): We score providers highly when they offer short response times, multiple ways to file claims, and around-the-clock availability. Companies can earn bonus points if they have a good reputation for quick and easy claims processing.
  • Availability (5 points): Providers that serve more areas can have experience dealing with a wider range of homeowner headaches. A company earns the maximum points in this category if it offers services in most U.S. states.

We monitor company data on an ongoing basis to keep rankings and information up to date.
