To find out whether a leak caused your high water bill, stop all water use in the house and watch the meter. If the leak indicator spins or the numbers climb, water is escaping somewhere. Then close your home's main shutoff valve and watch again. If the meter stops, the leak is inside your plumbing. If it keeps moving, the leak is on the buried line between the meter and the house.
A bill that jumps with no change in your habits is worth a few minutes of checking before you call anyone. Most spikes trace back to a short list of causes, and the meter itself will sort them out for you.
Below you will find the full test, a table for reading each result, the usual hiding places, and the point where a licensed plumber with listening gear should take over. The same logic drives professional leak detection, just with more precise tools. We dispatch from Winter Springs and also cover neighbors like Oviedo.
Run the meter test before you call anyone
You need five minutes, a pen, and a dry hand. Do this when nobody is using water.
Stop every source of water
Close all taps and make sure the dishwasher and washing machine are idle. Pause the ice maker if you can, and ask everyone at home to hold off on flushing.
Find and open the meter box
The meter usually sits in a ground-level box near the street. Lift the lid with a tool, not your fingers, because insects and snakes like the shade under it.
Read the leak indicator
Many meters carry a small triangle, wheel, or star that turns with even a trickle. Note the main number, wait 30 minutes, longer for a slow leak, and read again. Any movement means water is flowing.
Close the home shutoff and repeat
Shut the main valve where the line enters the house, then watch the indicator again. This one step splits the problem into two halves, inside the house or in the ground outside.
Write down what you saw
Record both readings and the time. A plumber can start from your notes instead of from zero, which saves diagnostic time.
What the meter is telling you
Match your result to a row. Each outcome points to a different next move.
| What you see | What it usually means | Next step |
|---|---|---|
| Indicator still with everything off | No continuous leak right now. The spike may come from heavy use, a leak that runs only in cycles, or a long billing period | Compare bill dates, then test again while irrigation or the water heater runs |
| Moves with everything off, stops when the home shutoff closes | A leak inside the house side, such as a toilet, supply line, water heater, or a pipe in a wall | Do the toilet dye test, then call for leak detection |
| Keeps moving with the home shutoff closed | A leak on the buried line between the meter and the house, or a bad shutoff valve | Call a plumber, since a line repair may involve digging |
| Moves only while a sprinkler zone runs | A broken head, cracked riser, or stuck zone valve | Run each zone alone and look for pooling water |
A slow leak can need an overnight test. Read the meter at bedtime and again at dawn with no water used.
Check the toilets first
Toilets are the most common cause of a quiet, expensive leak. A worn flapper lets water slip from the tank into the bowl all day with barely a sound.
To test, put a few drops of food coloring in the tank and do not flush. If color shows in the bowl after a while, the flapper is leaking. A new flapper is a simple fix for many homeowners. If the base of the toilet is wet or the tank rocks, stop and call for toilet repair, because the seal underneath may be failing.
Watching a meter that never stops
If the dial keeps turning with everything off, a plumber can locate the leak. Call (407) 964-8940 any hour. The line is open 24/7.
Other places water hides
If the toilets pass, look at these spots next.
Water heater
Look for a dripping discharge pipe from the relief valve and rust streaks near the base of the tank.
Sprinkler system
A stuck zone valve or a snapped head can run for hours. Wet, spongy patches in the lawn are the clue.
Supply lines
Braided hoses under sinks and behind the washer fail at the fittings. Swollen cabinet floors or a musty smell give them away.
Outdoor spigot
A hose bib that drips while a hose is attached wastes water faster than people expect.
Inside a wall or under the floor
A warm patch on the floor, the sound of running water at night, or damp drywall suggests a hidden pipe. Only a tester can confirm this.
When the meter test passes but the bill is still high
A clean test does not always mean the bill is wrong. Billing periods can run longer than you think, and summer irrigation, guests, or filling a pool can add up quickly.
A leak that runs only at certain times can also slip past a one-time test. An irrigation timer or a water heater that refills after use are common examples. Repeat the test while those systems are running before you rule a leak out.
Why a small leak shows up as a big bill
A leak does not need to be dramatic to cost money. A drip that falls every second runs day and night, and the meter counts every drop. Over a billing cycle that adds up to a bill that looks like you ran a hose for days.
Leaks that start slowly also fool people because the bill creeps up instead of jumping. If your last two or three bills each rose a little with no change in routine, treat that as a signal and run the test.
Pressure matters too. Water in a home line sits under steady pressure, so a pinhole in a copper pipe sprays or seeps constantly instead of waiting for you to turn a tap.
Know when to stop and call
The meter test and the dye test are safe for most homeowners. Stop and call a licensed plumber if you find water near electrical outlets or an electrical panel, if a ceiling is sagging, or if the floor is soft. Close the main valve first and keep power away from wet areas.
Renting or managing a property
Tenants usually cannot approve plumbing work, and they should not open walls on their own. If you rent, run the meter test, write down the results, and send them to the landlord or property manager with the date.
Managers get a faster work order approval when the report says which half of the system is leaking. A note that reads meter moves with the home shutoff closed gives the vendor a clear starting point.
Winter Springs water bills and who to call
According to the city utility page, the Winter Springs system serves 33,430 residents through 14,006 active potable connections and 244 miles of water lines. The meter at your curb belongs to that system, so leave its seals and fittings alone.
The city lists billing at (407) 327-5996 and customer service at (407) 327-1800. If you suspect a break on the street side of the meter, the city lists 24-hour utility emergencies at (407) 327-2669. Ask for your reading dates before you assume a leak, since an odd read can explain a spike.

What a plumber adds after your test
Your result tells us which half of the system to test first. From there a plumber isolates sections with valves, puts a gauge on the line to see whether pressure holds, and uses a ground microphone to hear where water escapes.
If the leak sits on the buried line, the fix may be a spot repair or a section replacement under water line repair. Be honest with yourself about limits. Listening gear narrows a leak to a small area, but it cannot see through soil, so the final location is confirmed when the ground is opened. Utility locates come first, and Sunshine 811 asks for at least two full business days before digging.
What to have ready when you call
A few details speed up the visit.
- Meter readings before and after the shutoff test
- Whether the meter stopped when the home shutoff closed
- The dates and amounts of the last few bills
- Any wet spots, warm floor areas, or sounds of running water
- Whether the home has a sprinkler system
- Whether you rent, so we know who approves the work
Questions readers ask
Wait 30 minutes, longer for a slow leak. If you want to be sure, read the meter at bedtime and again in the morning with no water used. Any change in the numbers means water moved.
Insurance typically covers sudden accidental damage, not wear, and not the repair of the failed part itself. Whether a high bill is covered depends on your policy, so ask your insurer before you start work.
Yes. A flapper that leaks runs around the clock, and nobody notices because the sound is faint. The dye test takes minutes and costs almost nothing.
Start with the city utility numbers in the note above. Ask the city Utility Division where city responsibility ends, so you know which side of the meter you are paying to fix.
Yes, we dispatch 24/7 from Winter Springs and serve Casselberry too. Same-day appointments are offered when available, and you get a clear price before work starts.
