When it comes to unexpected home repairs, water and sewer line issues can be some of the most expensive and inconvenient situations you can face. Such repairs often involve digging up your yard, and possibly part of the street in front of the yard. You can’t count on the local utility to pay for the fixes, because in most cases the costs fall on you, the homeowner.

Depending on the situation, you could be looking at an unexpected bill that runs at several thousand dollars. Thankfully, there are insurance and sewer line warranty options that help cover the costs of such water and sewer line disasters. Read on to discover what sort of sewer line plans are available and to see if you could benefit from them.

House Method recommends Choice Home Warranty, which offers coverage for plumbing system stoppages and optional septic system coverage.

Do I need a sewer line warranty?

Buried beneath your lawn, there are pipes that bring clean water into your house and take out dirty water and sewage. These pipes are known as sewer and water lines, and they run from your house to the municipal water and sewer lines under the street. If you aren’t connected to the municipal sewage system, your sewage line runs to your septic tank.

Many people incorrectly assume the utility is responsible for any problems in water and sewer lines, but in reality, homeowners are responsible for the lines running through their property and into their house.

If you call the water company about an issue with your sewer line, you may be in for a surprise. For example, about 70% of the Atlanta area homeowners who report issues to the local water and sewer utility find out they are responsible for the bill, because the issue is on their property and not in the utility’s part of the lines. The Fulton Water Resources Division says its customers end up paying an average of about $1,500 to fix a water leak and $3,500 for a sewer leak.

Your homeowner’s insurance probably isn’t going to cover these kinds of problems, either, unless you purchase a special rider for your policy that covers sewer backups or similar problems. For that reason, many municipal utilities urge their customers to purchase a warranty for their water lines. A sewer warranty is a service contract that covers sewer line repairs when the issue results from normal wear in your pipes.

Aging water lines cause headaches and costly repairs

Do you need to worry about the water and sewer lines to your home? The answer depends on what the lines are made of and how old they are. Newer homes typically use PVC pipes, and PVC pipes are less likely to break than other pipes. Homes built in the 1960s and 1970s usually have pipes made of cast iron, which can be damaged by corrosive soils. Pipes that were laid in the decades before the 1960s are often made of more fragile materials that are prone to breakage with age.

As the local water infrastructure ages, line breaks become more common. A Utah State University study found that water main breaks rose by 27% from 2012 to 2018 in the US and Canada. For cast iron pipes, breaks were up by 43% in that period. The study noted that more than 80% of cast iron pipes are more than 50 years old.

Rae Dolan, a real estate investor and property owner in Houston, told House Method her cast iron water line failed due to age, and she ended up paying $10,000 to replace it. (That bill is particularly high due to the size of the property, but a bill in the thousands isn’t unusual.)

Luckily, not every issue with a sewer line involves a break. The Georgia Plumbers’ Trade Association reports that clogged lines often just need to be unclogged rather than replaced. Prices for unclogging a sewer line, commonly referred to as snaking the line, can vary widely, depending on issues such as access to the line, length, and the cause of the clog. Clogs can be caused by buildup of grease or rust, or by tree roots that have intruded into the pipe and are creating a blockage. Snaking a complex clog can cost $200 to $500.

Sewer line coverage options

Many people begin to worry about their water and sewer lines when they notice neighbors having problems and replacing their lines. If you are worried about your sewer lines, you have several options for coverage.

  • A rider on your homeowner’s insurance policy. Damage from sewer backups aren’t covered under a typical homeowner’s policy or by flood insurance. You might be able to purchase an endorsement on your policy that provides coverage for your sewer line or for sewer backups for an additional fee.
  • Water line insurance. Some companies offer a policy that specifically covers your water line. If you live in a newer home, you may never have problem with your water line, and sewage clogs might be more likely in any home.
  • Service Line Warranties of America. This company specializes in water line and sewer line repair plans, which are service contracts that promise to send a qualified plumber to your home to fix covered repairs. The company maintains a 24/7 call center and has a list of prescreened plumbers it can call on. There is no deductible for covered repairs, and customers can make monthly payments or pay annually. SLWA has been endorsed by many municipal utilities.
  • A water or sewer line warranty offered through your utility. Some municipalities offer water and sewer line warranties by partnering with a warranty company. New York City, for instance, has partnered with American Water Resources. The warranty plan is similar to other warranties, but the advantage of the city partnership is that customers can pay the monthly premium as part of their utility bill. Sometimes these policies have a 30-day waiting period before they take effect.
  • A home warranty that includes a sewer or septic option. These protection plans are also service contracts that are designed to offset repairs costs. If the basic home warranty doesn’t cover septic elements, you might be able to add them as optional coverage.

Home warranties: Cover sewer lines and additional home systems

A home warranty can be a good way to protect yourself from the unexpected expense of a plumbing stoppage or septic issues. House Method recommends Choice Home Warranty, which offers plumbing stoppage coverage as part of both its Basic Plan and more extensive Total Plan. Choice Home Warranty also provides coverage of septic lines with its optional septic system coverage, which you can add to your home warranty.

Unlike a sewer line insurance plan, which only covers those lines, a home warranty provides coverage for many important systems and appliances that may experience problems due to normal wear and tear. A home warranty is a service contract, not insurance. If you have an issue with a covered system, such as a plumbing stoppage, you call the warranty company, which will send a qualified technician to your home to repair the covered item or system. All you have to pay is a service fee for the technician’s visit.

Choice Home Warranty’s plumbing stoppage coverage includes stoppages and clogs in the drain and sewer lines up to 100 feet from the access point, as long as there is an accessible ground level cleanout and the clog can be cleared by cable. It doesn’t cover broken lines outside the main foundation or clogs due to roots.

The optional septic system coverage includes a variety of pumps, the septic tank, and the septic line from the house.

Sewer maintenance tips

While water and sewer line insurance and warranty plans can provide some relief if you experience problems with your pipes, it’s best to try to prevent a backup from ever happening.

  • Don’t pour grease down the drain. Grease solidifies and can cause clogs in your drain or sewer line. Instead, pour used cooking oils into a heat-resistant container, let it cool, then put it in the trash.
  • Keep most paper products out of your pipes. Paper towels, disposable diapers and wipes, and feminine hygiene products don’t deteriorate like toilet paper does when flushed and can cause clog sewer lines. Put them in the trash instead of flushing them.
  • Manage tree roots. If tree roots are intruding into your water and sewer pipes, get a professional to trim the roots.
  • Put in plastic piping. Replacing old pipes with PVC pipes will keep the tree roots out of the pipes and eliminate the issues that come with aging pipes.
  • Install a backwater prevention valve. These valves are installed in basement sewer lines and prevent sewer water from backflowing into your home. Have a qualified plumber install the device.

Yuck, our sewer line backed up

Sewage backing up into your home is more than yucky—it’s a health hazard. The sewage can lead to disease, of course, but the backup can also result in electrical malfunctions, and the damp can lead to mold. Take these steps as soon as you discover a backup in your sewer line.

  • Keep kids and pets away from the area.
  • Turn off electrical power to the area if any electrical appliances or fixtures are in contact with standing water.
  • Turn off running water and don’t flush the toilets.
  • Notify the local water and sewer utility in case the backup is more extensive than just at your house.
  • Contact your insurance company or home warranty company.
  • Consider hiring a professional to clean up if the area is large or if the spill occurred more than 24 hours before you discovered it.

FAQs on sewer and water line insurance

Does my homeowner’s insurance cover sewer line issues?

The only way to be sure is to read your policy or to check with your insurance agent. Homeowner’s policies typically don’t include sewer insurance unless you specifically purchase a rider that covers sewer and water lines. You can ask your insurance agent to add such an endorsement to your policy. Most insurers, such as State Farm, offer such an endorsement.

Do I need sewer backup insurance if I have a septic tank?

Consult with your insurance agent. You may find that sewer backup insurance won’t cover septic issues, but you might want to get some coverage for your septic tank. Homeowner’s insurance usually doesn’t cover a septic system because it’s not considered to be part of the structure of the home, since it’s located away from the house. Some insurers offer a rider that covers septic tanks. But home insurance doesn’t cover the wear and tear that often results in septic system problems, so you might also want to look into a home warranty that includes your septic system.

Does homeowner’s insurance cover tree roots in the sewer line?

Probably not. Homeowner’s insurance protects against specific disasters or accidents that occur suddenly and unexpectedly. Tree roots intruding into pipes is a slow process that’s not likely to be covered. Check your insurance documents or ask your agent if the company offers a special sewer line endorsement that covers tree roots.
