How to Check Your Water Meter for a Leak: A Frisco Homeowner's Guide
Your water bill came in high this month, and nothing looks wrong. No puddle, no drip, no obvious sign. Yet the cost keeps climbing, and you want to know why. A hidden leak is one of the most common causes. Here we show you how to check your water meter for a leak in a few simple steps.
Your meter is a powerful tool for this job. It measures all the water flowing into your home. That makes it the best way to catch a leak you cannot see. When a Frisco homeowner calls us about a high bill, we start at the meter. We check the sweep hand, the low-flow dial, and then run a simple test.
Below, we walk you through finding your meter and reading the leak indicator. We also cover the step-by-step test, how to locate the leak, common causes, and when to call a pro.
How Do I Check My Water Meter for a Leak?
To check your water meter for a leak, follow these steps:
- Turn off all water inside and outside your home.
- Find your meter, usually in a box near the curb.
- Read the leak indicator — a small triangle, star, or wheel. If it spins with all water off, you likely have a leak.
- No indicator? Note the meter reading, wait one to two hours without using water, then recheck. A changed number means a leak.
This simple test catches most steady leaks. A spinning dial with the water off is your clearest sign.

Find Your Water Meter First
Before you can test for a leak, you need to find your meter. In most Frisco homes, it sits in a ground box near the curb or sidewalk. The lid is often marked "Water Meter" in metal or plastic.
To open it, lift the lid with a screwdriver. A few safety notes before you reach in:
- Lids can be heavy, so lift with care.
- Bugs or small animals sometimes hide inside the box.
- Replace the lid fully when you finish.
Once it is open, look at the meter face. You may have an analog dial or a digital display. An analog meter shows a round dial with a sweep hand and numbers. A digital meter shows the numbers on a screen instead.
Once you've found the meter, the leak indicator does most of the work.
How to Read the Leak Indicator
The leak indicator is the most useful part of your meter. It is a small triangle, star, or low-flow wheel on the meter face. This part reacts to any water moving through the meter.
How it moves tells you a lot:
- It spins fast when water is running.
- It moves slowly when water is only dripping.
- Any movement with the water off points to a leak.
If you have a digital meter, look for the flow-rate screen instead. When no water is running, that screen should read zero. Any number other than zero means water is flowing somewhere.
If the indicator moved, the next step tells you where the leak hides.

The Step-by-Step Meter Leak Test
Now you are ready to run the full test. Follow these steps in order:
- Turn off all water. Shut off every fixture and appliance, including irrigation.
- Watch the leak indicator. If the triangle, star, or wheel moves, you likely have a leak.
- No indicator? Record the reading. Write down the numbers on the meter face.
- Wait, then recheck. Leave the water off for one to two hours and read it again.
- Compare. If the reading changed with no water used, you have a leak.
One thing to keep in mind about this test. Some leaks start and stop, like a running toilet. Those may not show up if they are not running when you check. For a slow leak, a longer wait of several hours gives a clearer result. The U.S. EPA WaterSense program notes that a running toilet can waste hundreds of gallons of water a day, so it is worth catching.
Is the Leak Inside, Outside, or Underground?

Is the Leak Inside, Outside, or Underground?
Once you know a leak exists, the next step finds where it hides. This test uses your main shut-off valve. You can usually find it in a garage, basement, or near an outdoor faucet.
Work through these steps:
- Close the main shut-off valve to your house.
- Recheck the meter and watch the leak indicator.
- Read the result:
- If the dial stops, the leak is inside your home. A toilet is a common cause.
- If the dial still moves, the leak is between the meter and the house. This may be an underground line.
- Have an irrigation system? Shut off the water to it as a separate check. If that stops the dial, the leak is in your irrigation line.
If the indicator moved, the next step tells you what is likely causing it.
Common Leak Sources in Frisco Homes
The meter test tells you a leak exists. These are the usual culprits behind it:
Silent toilet leaks. A worn flapper lets water slip through without a sound. Test it with a few drops of food coloring in the tank. If color reaches the bowl without flushing, the flapper leaks.
Faucets, appliances, and hoses. Dripping faucets, old washing machine lines, and garden hoses all add up.
Irrigation leaks. These are common with North Texas summer watering schedules.
Underground service lines. Corrosion, shifting soil, and root intrusion can crack the line between your meter and home.
Some of these you can spot and fix yourself. Others hide underground or behind walls, out of plain sight.
Some leaks are simple fixes. Others need a trained eye.
When to Call a Frisco Leak Detection Pro
Some leaks are beyond a do-it-yourself test. Call a pro when you see these signs:
- The dial still moves after you shut off the house and irrigation. That points to a service-line leak.
- The leak hides behind a wall, under a slab, or underground.
- You notice stains, mildew, or moisture on walls, floors, or ceilings.
- Your water bill stays high with no clear cause.
These leaks are hard to find without the right tools. We use specialized equipment to pinpoint the source without digging up your yard. That means less damage and a faster fix.
Catching a leak early limits water waste and protects your home. The sooner it is found, the less it can harm your floors, walls, and foundation. For more leak-finding tips, the U.S. EPA's WaterSense leak guide is a helpful resource.

Yes, a silent toilet leak can waste water all day and raise your bill. A worn flapper lets water slip from the tank into the bowl. Test it by adding food coloring to the tank and watching for color in the bowl.
Call a plumber when the leak hides underground, behind a wall, or under a slab. Stains, mildew, or a high bill with no clear cause are also signs. We use specialized equipment to find the source without digging.
