Different types of water damage exist. For instance, bathtubs and washers are both prone to overflowing. Visualize arriving home one day to find a sewage or water backup. These risks might be problematic for you and your insurer because a typical homeowners policy rarely covers them.

Sewer backups, often known as 'water backups,' are happening increasingly more. But unfortunately, many homeowners may not realize they are typically not covered by most insurance. Cleaning, repairing, and replacing the damaged objects in your home could be expensive, depending on the degree of the damage.

Unless you have bought a specific sewer backup coverage, your standard homeowners insurance is unlikely to pay for this damage. Continue reading to know more about sewer backup insurance and what alterations you need to make to your home policy to receive full protection.

Key Takeaways

  • A standard home insurance policy doesn't have sewer backup coverage.
  • The yearly rate of a home insurance policy with an additional $20,000 in sewer backup coverage costs nearly $1,249.
  • Sewer backup coverage doesn't offer protection for damages that happen due to flooding.

What causes sewer backups?

Several things can cause sewage to back up into your home. First, it can be expensive property losses, whether only a tiny leak or an ankle-deep flood. So, always ensure to have sewer backup insurance to cover the damages. Typical causes of sewer backups include these.

  • Clogged pipes: Drain pipes can clog for many reasons, including poor maintenance, flushing non-biodegradable objects down the toilet, and pouring a lot of food scraps down the garbage disposal, to name a few. Sewer backups in other house areas could become a bigger issue if the obstruction continues.
  • Tree roots: Strong tree roots can entangle underground pipes, causing them to burst and collapse and causing sewer backups. As soon as you become aware of slow drains and strange noises, have them checked to possibly stop tree roots from harming your sewer system.
  • Broken line: Sewage can frequently enter your property if the line connecting your home to the main gets damaged. If you think this is the cause of the sewer backup in your home, get in touch with your local municipality.
  • Older sewer systems: Old plumbing systems can lead to several issues. Many systems age and become increasingly prone to backups and other problems.
  • Combined pipelines: If sewer and storm drainage pipes are combined, you can experience problems during a storm in your city. Heavy rainfalls can cause major issues with water backup in your home.

How to best prevent Sewer backups

Here are some safety measures to avoid a sewer or sump pump blockage.

  • Occasionally cut tree roots.
  • Dispose of paper goods properly.
  • Plan periodic maintenance checks of your sump pump.
  • Get rid of grease properly.
  • Try to install a backwater protection valve that could prevent sewage water from coming back in.
  • Check whether there are any illegal plumbing connections. French drains, sump pumps, and other flood control systems linked to your sanitary sewer should be repaired by calling a plumber, who can also clear your lines of debris and silt.

Does homeowners insurance include sewer backup coverage?

No. A standard home insurance policy doesn't cover sewer backup. However, many home insurance providers provide it as extra coverage on top of the regular homeowners insurance plan. The coverage provides a specific amount of coverage that will cover sewage backup and water backup claims.

So, having sewer backup insurance will always be beneficial for a homeowner. If you chose sewer backup coverage, your homeowners policy would likely provide coverage for the following two instances of sewer backup.

  • If your sump pump malfunctions after a severe downpour, water will back into your basement, causing structural damage to your house and your possessions.
  • When tree roots enter the septic pipe outside your house, the sewage backs up and floods your house with sewer water. So, to repair the broken septic line and remove the tree roots, you should dig up your yard needs and replace all of the personal items in the basement.

What does sewer backup coverage include?

Sewer backup insurance covers damage to the sewer pipe connecting your home to the city main. It also covers the cost of having standing sewage removed from your home and repairing any damage it causes.

Remember that sewer backup insurance does not cover your home's broken or malfunctioning plumbing system. Normal dwelling coverage sometimes covers this, but it may vary by your insurer. Additionally, sewer backup insurance will not cover problems that develop gradually over time due to poor maintenance. Before buying sewer backup protection insurance, read the fine print to know its applicable conditions.

Flood insurance also differs from sewer backup coverage. Since sewer backup flooding directly results from the septic system, flood insurance won't provide coverage. Likewise, your sewer backup insurance does not cover flood damage due to your sewer lines or septic system.

How much does sewer backup coverage cost?

The annual cost of a home insurance policy with an additional $20,000 in sewer backup coverage comes to around $1,249. Most homeowner insurance policies allow for the addition of sewer backup coverage, which normally costs an additional $50-$250 a year. Numerous factors, like the weather in your area and the coverage limits you select, will affect your cost.

These are the average annual rates of some of the top home insurers.

Insurer Average without backup coverage $10,000 limit $20,000 limit $30,000 limit $40,000 limit

Does sewer backup insurance cover flooding?

No. Sewer backup insurance doesn't cover damages due to flooding or surface water. Therefore, you would require additional flood insurance coverage to cover flood damage. Although certain insurers might provide flood coverage as extra, the National Flood Insurance Program (NFIP) is typically the only source of flood insurance.

Four reasons to add water backup coverage

These are the main reasons homeowners should add water backup coverage to their policy.

  • First, a standard home insurance policy doesn't include water backup coverage. Without this coverage, you must pay for any cleanup expenses or damage brought on by a sump, a sump pump, or other comparable equipment that is not a plumbing system or home appliance.
  • Adding this coverage isn't expensive. Based on your risk exposure and the limits you choose, water backup and sewer coverage typically cost $50 to $250 a year.
  • Water backups can happen to anyone at any time. For instance, water backup can happen if you live on a hilltop or your home doesn't have a basement.
  • If your house is uninhabitable, you are eligible for Loss of Use coverage. For instance, a sump pump failure usually does not make your home uninhabitable, so you could continue to live there after cleaning. However, having water backup coverage would entitle you to Loss of Use coverage in the unlikely event that it turns your house inhabitable.

Is sewer backup insurance worth it?

When water damage results from backups, a few paper towels may not always be sufficient to remove them. Sewer backup coverage can help in this situation. If you don't have this coverage, you might have to pay for losses out of cash. Assess your policy documents or contact your insurer to determine if your current home insurance policy covers sewer backups.
