Jump right to it: The best sewer and water line insurance plans are offered by Choice Home Warranty.

Your home insurance may have some expensive coverage gaps when it comes to sewer lines. If your sewer line fails, chances are good that you’re on the hook for repairs, which could cost thousands.

Water and sewer line insurance promises to protect your home from sewer line damage and other risks in exchange for a monthly premium or fee. Here’s what to consider.

The Best Sewer Line Insurance

When choosing water line protection or a sewer line insurance plan, you’ll find similar coverage available through warranty providers and insurers. However, some coverage plans may have deductibles, hidden costs or gaps in coverage that can cost you money if you need a sewer line repair.

It’s also important to note that sewer line coverage does not cover damage to your home. For sewer backup or sump pump overflow coverage, ask your home insurance provider if you can get a rider.

What is Sewer Line Insurance

Sewer lines and most service lines running from your house to a utility aren’t covered by standard home insurance. Some insurers offer a rider, an add-on that extends limited coverage, and there are also companies that sell sewer service line coverage as a standalone contract or as part of a larger home warranty.

Remember, too, that a water line break or sewer line replacement could require a second mortgage on your home because the expense is so great. A water leak could cause your water bill to rise by thousands of dollars in a short time, but a service line warranty program covers repair costs with a small service fee and upfront or monthly premium.

What Does Sewer Line Insurance Cover?

Sewer lines can fail over time, either collapsing, becoming clogged or invaded by roots. Line coverage, however, is specific tot he situation, and every repair plan will be a little bit different.

If the problem requires digging and line replacement, you can expect to pay even more. This is why you want an insurance policy or warranty that handles line repair, pipe replacement, associated home repairs, etc.

There are a few considerations before buying coverage. Your home insurance company likely won’t cover damage from sewer backup. Often, this is available as an add-on and is separate from coverage for sewer lines themselves. The utility company isn’t responsible because it must maintain the system, not your home.

A smaller group of insurers also offer service line endorsements, add-ons that provide coverage for sewer line failures which expand your home insurance coverage. Specialized coverage for sewer lines is also available from a number of dedicated providers or home warranty companies.

Some home sellers might offer warranty coverage for the water main, sewer pipes, etc. This could be helpful if you’re selling an older home or want to add an incentive that makes the house easier to sell, especially when you’re passing homeowner responsibility for the plumbing system, gas line, water lines, etc. to the buyer.

Average Cost of Sewer Line Insurance

When purchasing a sewer line policy as standalone coverage, expect to pay about $10 to $15 per month or higher.

We found plans that only covered sewer lines for under $10 per month, although pricing and availability may vary by location. Many providers for sewer protection partner with regional utility providers or only service select areas.

If your insurer offers a sewer line endorsement, your monthly cost is likely to be lower. However, if a deductible applies, the savings may be erased if you have a claim. It’s unusual to find a home insurance deductible of less than $500 and a $1,000 or higher deductible is more common.

Consider the deductible when comparing prices for coverage.

Who Needs Sewer Line Insurance?

Insurance is designed to cover life’s larger financial losses. Sewer line service is likely to cost thousands, so it’s worth considering. Older homes are more likely to need sewer line repair as pipes age.

To dive deeper, you have to look at the pipes. In homes built before the 1950s, sewer pipes were commonly made of clay, cast iron or a fiber conduit called Orangeburg. Of these pipe types, Orangeburg has proven itself to be the most problematic due to its porous nature. It absorbs moisture and its tendency to deform under pressure.

Orangeburg was used often in homes up until the 1970s. Even newer materials like ABS or PVC aren’t designed to last forever. Consider the potential cost of replacement when deciding if sewer line coverage is a good value.

For example, estimates the average cost to repair a sewer line at over $2,500 but cautions that costs could run much higher. If you were able to secure coverage for about $10 per month, your cost for a year of coverage is $120 for a year or $1,200 for a decade.

Clay pipes can last up to 50 or 60 years, while PVC can last over 100 years. If you have either of these types of pipes and you have a newer home, it’s unlikely that you need sewer line insurance.

Building an emergency savings account is a thriftier option. However, if your home is older, you may be on borrowed time. If you suspect you may have a sewer line failure sometime within the next 10 to 20 years, sewer line coverage can be a money-saver.

Does Homeowners Insurance Cover Sewer Lines?

This all depends on your provider, but sewer line coverage is often not built into a standard homeowners policy. Some providers do include it, though, and others offer it as an add-on or standalone policy. Some insurers may offer home warranties that include sewer line damage. Check out some of Benzinga’s favorite homeowners insurance policies and some insurance basics to see if they offer sewer line coverage as part of their available products.

Choosing the Right Sewer Line Insurance

Sewer line coverage can be purchased as either a sewer line warranty product or as an add-on to your home insurance policy. Some insurers that offer service line coverage as an endorsement don’t advertise the coverage. Check with your home insurance provider or agent to see if there’s an add-on available. Check with competitors, too. If service line coverage is a priority for you, it may be worth considering a switch to an insurer that can provide the coverage you need.

Warranties or sewer pipe protection plans are often offered without deductibles but can be more costly on a monthly basis. As always, read the fine print before making a commitment. Many plans have exclusions that may affect coverage for your home.

Frequently Asked Questions


How do I know if my sewer line is broken?


There are several indicators that there is trouble with your sewer line. Signs can include sewage backup, unpleasant smells, slow or stopped drains, mold and foundational cracks. An influx of pests can also be a big sign.

The best route when you suspect you have a sewer line issue is to call a professional, such as a plumber, to assess.


How long does a sewer line repair typically take?


This all depends on the extent of the damage and the location of the sewer line. However, the general consensus is that a repair will take an average of 1 to 3 days. Some repairs could be a quick fix and only take an hour or so — others may drag on longer than a week.

That’s why having sewer line coverage will not only save you money, it will save you from added stress when you least need it.


Is sewer line insurance worth it?


Sewer line insurance is often worth the money because repairs can be quite expensive and a leaking sewer line can be both extremely disruptive and even incur environmental violations from your municipality.
