What to Do When Your Water Meter Is Leaking

Who Is Responsible for a Water Meter Leak?

Your water utility owns the meter and the service line up to it, including the meter itself. You own everything from the meter's outlet into your home, and that line decides who pays to fix a water meter leak.

The valve near the street, often called the curb stop, roughly marks where the utility's pipe ends and your private service line begins. Utility Explained describes the rule simply: the utility repairs the pipe up to and usually including your meter, and you own everything from the meter's outlet onward.

The meter is sealed utility equipment. According to MainLink, cities typically own the physical meter and at least part of the public service line, so you should never try to open, repair, or replace it yourself.

How to Tell if Your Water Meter Is Leaking

Most residential meters have a small leak indicator, often a red or blue triangle or a snowflake-shaped wheel, that spins whenever water moves through the line. If it keeps turning with every faucet, toilet, and appliance off, water is moving somewhere in the system.

Water sitting in the meter box is not always a leak. A home inspection resource, How to Look at a House, notes this is often just heavy rain and saturated ground, especially when the meter sits in a low spot on the property.

A real leak looks different. Water bubbles up from inside the box, or the ground around it stays muddy when the rest of the yard is bone dry, even after days without rain.

• The leak indicator dial keeps spinning with every fixture and appliance off
• Water bubbles or flows from inside the meter box itself
• The ground around the box stays muddy while the rest of the yard is dry
• Your metered usage rises sharply with no new water use in the house

San Diego's Public Utilities department lists similar signs: standing water in the box, soil that stays saturated, and a steady flow of water from the meter rather than the occasional trickle you would see after rain or nearby irrigation. Our guide to detecting a hidden leak covers more signs that show up before your bill does.

Even a small leak matters. The EPA's WaterSense program notes that a leak just 1/32 inch across, about the thickness of a dime, can waste roughly 6,300 gallons a month in a pressurized line, a useful comparison for how much even a tiny meter-side leak can add up to.

What to Do If You Find a Water Meter Leaking

Shut off your home's main water valve, then watch the meter's leak indicator. If it stops moving, start by calling your water utility, since many utilities repair meter and service-line leaks on their own side at no cost to you.

1. Find your main shutoff valve, usually near where the line enters the house or at the curb stop
2. Turn the valve fully off and watch the meter's leak indicator for a minute or two
3. Write down the reading and take a photo of the meter and the leak indicator
4. Call your water utility's customer service or emergency line to report the leak
5. If the leak turns out to be on your side, call a licensed plumber instead

Do not try to repair or open the meter yourself. It is sealed utility equipment, and tampering with it can lead to a fine or an estimated-usage bill while the utility sorts out the damage.

A sudden jump in your bill is often the first clue something is wrong. Our guide to a high water bill from a hidden leak walks through how to read that pattern on your statement.

Determining If a Leak Is Before or After the Meter

Turn off your main shutoff valve, then watch the meter's leak indicator for a few minutes. If it keeps moving, the leak sits before the meter, on the utility's side. If it stops, the leak is after the meter, on yours.

Utility Explained calls this the ten-minute shutoff test, and it is the simplest way homeowners can narrow down a leak without digging anything up.

1. Locate your main shutoff valve, inside near the point of entry or at the curb stop outside
2. Turn it off completely and make sure no water is running anywhere in the house
3. Check the meter's leak indicator right away, then again after about ten minutes
4. A dial that keeps moving points to a leak before the meter, on the utility's side
5. A dial that has stopped points to a leak after the meter, somewhere on your property

Because many of these leaks run underground, the detection methods overlap with our guide to finding an underground water leak, which covers soggy spots, sound testing, and soil changes away from the meter box.

Water Meter Leak Repair Costs

A leak in the meter or its connection fitting is utility-owned equipment, so it usually costs the utility to fix, not you. A leak on your side of the meter, in the underground service line, is a different story.

Utility Explained puts homeowner-side underground service line repairs at an average of $990, with a typical range of $350 to $1,665.

If you choose to hire a plumber directly for a fitting leak instead of waiting on the utility, Fixr's cost data puts a general water line leak repair at $300 to $3,000, depending on how hard the leak is to reach.

If testing shows the service line itself needs to be replaced rather than patched, our guide to repairing a water line covers what that job involves and how it is typically priced.

Is a Water Meter Leak Covered by Insurance?

Usually not. Standard homeowners insurance covers sudden, accidental water damage, but it excludes gradual leaks and ordinary wear and tear, and most meter leaks develop slowly over time.

American Family Insurance explains that standard policies cover sudden, accidental events, not damage that built up gradually. A slow drip at a meter connection or an aging service line usually falls on the wrong side of that line.

Coverage for the service line between the main and the meter also varies by utility: some treat it as their own responsibility, while others expect the homeowner to cover part of it. Either way, it is rarely a simple homeowners insurance claim.

Some insurers offer an optional service line endorsement that can help with the underground pipe on your side of the meter. Ask your agent what it costs and covers under your specific policy, since terms vary by insurer and state.

For more on what your policy does and does not cover on the pipe itself, see our guide to insurance coverage for the main water line.

Temporary Fixes for Water Meter Leaks

Never open or try to repair the meter itself; it is sealed utility equipment. If the leak is at a fitting on your side, you can sometimes tighten the connection or add a rubber repair clamp until a plumber arrives.

• Do not touch, open, or attempt to repair the meter itself
• Tighten a visibly loose fitting on your side of the meter if you can reach it safely
• Wrap a rubber repair clamp around a leaking service line pipe as a temporary stopgap
• Call a licensed plumber the same day; clamps and tightened fittings only buy you time

For an underground service line leak, a rubber clamp paired with plumber's epoxy can slow the loss while you wait, but the pipe still needs a permanent, professional repair afterward.

Water Meter Leak Prevention and Maintenance

Check your meter reading once a month against your water bill; a sudden jump with no change in habits usually means a hidden leak. Ask your utility to mark your service line so you know exactly where your responsibility starts.

Freeze and corrosion are common causes of the pipe failures behind many meter and service-line leaks. Our guide to why pipes burst covers the same conditions that damage buried lines near the meter.

Keeping exposed pipes insulated, as described in our guide to preventing frozen pipes, lowers the odds of a freeze-related failure at the meter or along your service line.

Keep the area around the meter box well drained. Standing water and saturated soil make it harder to spot a real leak early and can hide a small problem until it grows expensive.
