When a home’s water service line leaks or breaks, the homeowner can be stuck with growing puddles, a big headache — and major repair bills.

If you are the customer of a water utility, and you can turn on a faucet in your home and get running water without any hassle, you have a water service line. It’s vital to your quality of life, and you rely on it every day. If your home’s water service line stopped delivering water the way it should, repairs would be needed — repairs best left to a professional.
A water line warranty is a program that protects a homeowner from the costly repair bill and inconvenience associated with water service line damage and subsequent repairs. It’s a protection plan — or a service contract — that entitles a homeowner to professional repair services in the event that a covered problem occurs. In the case of a water line warranty, those repair services generally include (but are not limited to):
Sometimes people refer to coverage for water service line repairs as “water line insurance,” however, the coverage that protects you for repairs to the underground water service line is more likely to be a water line warranty. It’s important to know that water line coverage typically isn’t included or covered with a standard homeowner’ insurance policy.
If your home has running water and you aren’t getting it from a well, you have a water service line. Many homeowners mistakenly believe that their homeowners’ insurance policy will cover any water line problem that their local utility doesn’t. However, standard homeowners’ insurance policies typically do not cover water line repairs, and water utility companies are typically not responsible for water line damages or repairs on private property — their responsibility usually ends at the property line or the street.
As the water service line travels underground between the property line and the home, its maintenance and repair are usually the homeowner’s responsibility. (If you live in dwelling like a condominium, please contact your local homeowner’s association to determine your specific responsibilities.)
For any residential homeowner who is responsible for the water service line attached to their home, it’s wise to consider enrolling in a water line warranty in order to help protect their home and budget.
A water line warranty covers repairs for problems with a home’s water service line, which is usually located underground. Warranty coverage typically includes a visit by a professional to determine the extent of the problem and how best to fix it (including what equipment and how many people will be necessary), permit application(s), a request for utilities to come to the property and mark underground service line locations, and the repair work itself. Excavation is usually needed to expose the problem with the water service line in order to make covered repairs.
After the water service line is repaired, the service professional typically takes care of scheduling an appointment to get the repair inspected. If the inspector determines that additional work is needed, the service professional performs the work and schedules a follow-up inspection. Once the repair work is approved, the pro will backfill the excavated area.
As long as you can turn on a faucet in your home and the water runs, and as long as you can flush your toilet and the bowl refills with clean water, you probably won’t give your water line a thought. But this line can be subject to corrosion, ground shifts due to weather and other causes, tree root growth, and other damage and hazards. Lines can leak and break — even underground. When that happens, the water pressure in the house can drop, the ground outside might become soft and spongy, and wasted water might begin to pool in the yard.
When there’s a problem with your home’s water service line, you may still have some water flowing in your home — or you might not. Here are things that homeowners should keep an eye out for. All of these could be symptoms of a problem with your water service line. And if your water meter is located near your curb — before the water reaches the leaking or damaged pipe under your yard — then you could be paying for water that’s not even getting to your house.
Many people hear the words “water line” and immediately think of the plumbing supply and wastewater lines that are inside a home. They may hear or say the words “water line home warranty” when what they really have in mind is a plumbing warranty or a clog repair warranty. They are different. A “water line warranty” specifically protects the water service line that’s outside a home and runs underground, and not a lot of companies offer them.
Here are the steps a homeowner will typically follow to enroll in and use a water line warranty for their home:
You can generally expect to pay between $5 and $10 per month for a water line warranty. The price will vary based on the warranty company, coverage limits, deductibles, service fees and your location. Some warranty companies offer homeowners the opportunity to bundle multiple warranty plans and save compared to buying plans separately.
Based on 2022/2023 AWR internal claims data, repairing (or replacing) a water service line typically costs $2,963, and without a warranty plan that would all come out of your pocket. Your costs could be lower, or they could be a lot higher — AWR paid a water line claim for $24,000 in 2022, and another for $14,057 in 2023. According to Forbes, “corroded piping can sometimes call for repairs on part of your water line, but in other cases it can call for complete replacement. Typical costs for this type of repair can run $600 to $5,000.”1
Because a water line warranty covers a home’s water service line — the line that’s underground and brings water to the home — there are some exclusions. Indoor plumbing and fixtures are not covered by a water line warranty. Some water line warranty plans cover the service line until it reaches a main shutoff valve or water meter located inside the home. Carefully read the terms and conditions of any warranty plan to know what is and is NOT covered. PRO TIP: Many home warranty companies that offer water line warranties also offer in-home plumbing warranties. You may be able to save money and cover more by bundling a water line warranty plan with an in-home plumbing warranty plan.
If you have a choice of water line companies and plans where you live, these are some of the considerations you’ll want to look for and compare as you make a choice:
