Does home insurance cover sewer backup?

Water damage can happen in all kinds of ways — an overflowing washer, a backed-up sewer line, or heavy rain that floods your home. But not all of these situations are covered by a standard homeowners insurance policy, which can lead to costly surprises.

The Insurance Information Institute reports that sewer, or “water,” backups are happening more often.[1] Still, many homeowners don’t realize this type of damage usually isn’t included in their coverage. Here’s what to know about sewer backup coverage and how to make sure your policy keeps you protected.

What is a sewer endorsement?

Sewer backup coverage (usually an endorsement to your home policy) helps protect your home against damage related to water that backs up through your plumbing system. Sewer backups can cause thousands of dollars in damage. Unfortunately, most homeowners are not covered under a standard homeowners insurance policy. To make sure you are adequately covered, you should seek a special sewer backup endorsement or, in some cases, a separate policy. 

Most home insurance companies offer a sewer backup endorsement. This typically carries a coverage limit between $5,000 and $25,000 to cover your personal property or structural damage caused by the backup. 

Make sure your home is covered for unexpected scenarios!

What causes sewer backups?

The pipes under your house are probably not something you think about too often unless they aren’t working properly. Along with your own plumbing system, many homeowners may not know that they are responsible for the sewer line that connects their home to the city’s sewer main. When an issue arises with these systems, backups can occur.

Below are some of the most common reasons for sewer backups:

Tree roots

As they look for moisture underground, tree roots can find their way into older or cracked pipes, slowly causing extensive damage or blockages. Responsibility for fixing the pipes and taking care of the roots often falls to the owner of the tree. A plumber may be able to check your lines with a camera to see if there are any possible problems with tree roots.

Older sewer systems

Aging plumbing systems can cause a lot of problems. As they get older, many systems become more susceptible to backups and other issues.

Combined pipelines

If your city combines sewer and storm drainage lines you could see problems during a storm. Heavy rains can overwhelm the system and create water backup issues in your home.

Blockages in the sanitary main

City sewers are susceptible to blockages as well. This usually happens over time and can result in water backing up into your home.

Sump pump failure

Most of the time, a sewer backup endorsement will also cover damages resulting from sump pump failure. A sump pump is a device that disperses water in order to prevent your basement from flooding. If this pump fails, you can possibly face thousands of dollars in damages. Note that while it may pay for damage caused by sump pump failure, it may not cover the cost to replace the pump itself. 


What does sewer backup insurance cover? 

In general, it can cover your damages caused by water backups as well as the cost of removing excess water from your home. Be aware that it does not cover floods that result from rising surface water or rainwater that leaks into your basement through a cracked foundation.


Does sewer backup insurance cover flooding?

Sewer backup insurance doesn’t cover damage from surface water or typical flooding. To be covered against flood damage, you would need to add a separate flood insurance policy. Flood insurance is generally available through the National Flood Insurance Program (NFIP), though some insurance companies may offer protection as well.[2]

How much does sewer backup coverage cost? 

The average cost of home insurance policy with $20,000 in added sewer backup coverage is $1,237 annually (less than the typical annual cost of home insurance). Sewer backup coverage can be added as an endorsement to most homeowners insurance policies and typically runs from around $50 to $250 extra a year. Your cost will be determined by a number of factors in your area, including your local weather and the coverage limits that you choose.

Is sewer backup insurance worth it? 

Sometimes a few paper towels aren’t enough to clean up water damage from backups. This is where water backup coverage comes in. This insurance can cover damages that may otherwise leave you paying out-of-pocket. If you are currently insured, the best way to find out if your current home insurance policy covers sewer backups is to check your policy documents or contact your insurance agent directly.

When you are shopping for affordable insurance, check to see if your new company offers this insurance coverage standard or if it requires a separate policy or endorsement

Sewer backup insurance FAQs:

No, standard homeowners insurance usually excludes damage from sewer or drain backups, but you can add coverage through an endorsement.

Typically no — homeowners insurance doesn’t cover normal wear and tear or replacement of sewer lines, though it may cover sudden, accidental damage if endorsed.

A toilet backup is usually not covered under a standard policy, but damage may be covered if you have sewer or water backup coverage added.
