La Mirada Leak Repair Tools
Find a Hidden Water Leak in Your La Mirada Home (Water Meter Test)
Enter two Suburban Water Systems meter readings to confirm whether an active leak is running, how fast it is losing water, and what it is adding to your monthly bill.
Call (562) 488-9614The water meter at your curb is the most reliable way to confirm whether your La Mirada home has an active hidden leak. La Mirada is served by Suburban Water Systems on Schedule WLM-1, a tiered rate structure where higher monthly usage costs more per CCF (hundred cubic feet). That means a moderate leak here costs significantly more than the same leak in a flat-rate water district. Knowing the exact loss rate from your meter reading helps you understand both the urgency of the leak and the real cost to your Suburban Water Systems bill.
A hidden leak almost never announces itself. A pinhole in a copper supply line under a La Mirada slab can run for months before a warm patch appears on the floor or the bill climbs high enough to notice. The overnight meter test below catches any active pressurized loss, from a dripping faucet at a fraction of a gallon per hour to a slab leak losing dozens of gallons per hour silently under the concrete.
Before you run the test
How to Read Your Suburban Water Systems Meter in La Mirada
- Turn off every water fixture and appliance in the home, including the irrigation controller and the ice maker valve behind the refrigerator.
- Locate your Suburban Water Systems meter at the curb in the small rectangular box flush with the sidewalk. The lid lifts with a flat screwdriver. Read the number displayed on the dial face.
- Wait at least two hours without using any water in the home.
- Read the meter again and enter both numbers in the tool below.
The tool works in gallons or CCF. Most Suburban Water Systems meters in La Mirada display in CCF. If yours shows CCF, select that unit and the calculator will convert to gallons automatically.

Understanding the results
What the Gallons-Per-Hour Rate Means for La Mirada
A loss of less than one gallon per hour is most often a fixture issue: a dripping faucet, a faulty toilet flapper, or a weeping garden hose bib. These are inexpensive to fix and rarely require professional detection equipment. A loss in the one-to-eight gallon-per-hour range usually points to a running toilet or a supply line leak that can be found visually.
Above eight gallons per hour, the picture changes significantly. At that rate, the most likely sources in a La Mirada slab home are an active slab leak, a fault in the underground water main between the meter and the house, or a stuck-open irrigation zone. All three are below-grade and invisible from the surface. Acoustic correlators, electronic signal tracing, and thermal imaging are the tools that find them without opening the slab or digging the yard speculatively. Professional detection locates the exact point before any concrete is cut or soil is excavated.
About Suburban Water Systems Tiered Billing
Suburban Water Systems uses conservation-tier pricing under the California Public Utilities Commission. Monthly usage above the tier break is charged at a higher per-CCF rate than baseline use. A significant hidden leak does not just waste water at a flat rate. It can push your entire monthly bill into the higher tier, where every CCF you actually use for cooking, bathing, and laundry also costs more. The meter test result above accounts for this tier stacking in the cost estimate.
If you want to see how your specific leak type compares in cost, try the Leak Cost Calculator, which covers dripping faucets, running toilets, and irrigation leaks individually.
La Mirada-Specific Context
The majority of La Mirada homes were built on concrete slab foundations during and after the Olive Mirada Ranch development in the 1950s and 1960s. Copper supply lines installed then have now been carrying hard Metropolitan Water District water for 60 to 70 years, and pinhole leaks in this profile are among the most common hidden leak types in the city. A pressurized loss that shows on the meter but produces no visible drip anywhere in the home is a strong indicator of a slab supply-line leak. The Slab Leak Risk Checker helps score your symptoms alongside the meter reading. Our blog post on why your La Mirada water bill doubled covers the billing mechanics in more detail, and the hidden-leak checklist walks through every other source to rule out before calling.
Common questions
Questions About the Water Meter Test in La Mirada
How do I read my Suburban Water Systems meter in La Mirada?
Your meter is in a small rectangular box at the curb, flush with the sidewalk. Lift the lid with a flat screwdriver. The face shows a numeric display in gallons or CCF. Read the full number including leading digits. Most meters in La Mirada display in CCF (hundred cubic feet). If yours shows CCF, select that unit in the tool above and the calculator converts automatically.
Why is my La Mirada water bill so high with no visible leak?
A pressurized leak under a slab or underground rarely produces a visible drip inside the home. The water escapes into the subgrade soil and spreads without reaching a drain. The only visible signs are indirect: a warm floor patch, an unusually green strip of yard, or a meter that moves with all fixtures off. The meter test above confirms whether loss is occurring even when nothing visible is present.
Does a running toilet show on the water meter?
Yes. A toilet that passes water from the tank to the bowl continuously registers on the meter the same as any other demand. A running toilet can waste 2 to 8 gallons per hour, which adds 1,400 to 5,760 gallons per month. The meter test catches it. The dye test (food coloring in the tank, wait 15 minutes, check the bowl for color) confirms whether a toilet is the source.
Can a slab leak cause a high water bill in La Mirada?
Yes, and it is one of the most common causes of unexplained high bills in the city. A pinhole in a 1960s copper supply line under the slab can lose 5 to 30 gallons per hour silently into the soil beneath the concrete. At Suburban Water Systems tiered rates, 30 gallons per hour amounts to roughly 21,600 gallons per month, well into the upper billing tier. Acoustic detection locates the exact point without opening the slab speculatively.
