Silent Leak Test · FL Meter Types · Slab Leak DetectionMost FL residential water meters are in a concrete box near the street (right-of-way), typically 1–3 feet from the sidewalk or curb. Lift the lid (watch for spiders and wasps common in FL meter boxes) with a screwdriver or meter key. The meter records cumulative water use in gallons or cubic feet — check the face for units. To find monthly use: subtract last month's reading from this month's reading.
Odometer-style digit display shows total gallons or cubic feet used. A large sweep dial (1 full rotation = 1 gallon or 10 gallons depending on model) indicates current flow. If the sweep hand is moving with all faucets off — you have a leak. Also has a triangular or star-shaped low-flow indicator: a small red or black triangle or star on the meter face. Even slow leaks (dripping toilet flapper, slow irrigation) will spin this indicator. Reading: record 6 digits on the register; ignore black-background digits (fractions of a unit) on some meters.
Contains an encoder-receiver-transmitter (ERT) module on top of the standard analog meter. Utility trucks drive by and wirelessly read the meter — no need to open the box for utility reads. Still has the visual analog register you can read manually. The ERT also broadcasts an ID and register value — some FL utilities (Orange County Utilities, JEA, Palm Beach County Water) offer customer-facing apps or online portals where you can view hourly water usage data, helping identify exactly when leaks occur.
Two-way communication meter — transmits usage data to utility in real-time or at intervals (typically 15-minute reads). FL utilities with AMI systems include Miami-Dade WASD, Broward County, Tampa Water, Orlando Utilities. AMI meters enable: automatic leak alerts from utility, time-of-use billing in some systems, and detailed usage dashboards. If your utility has AMI meters, log in to your online account — you can see exactly when and how much water is being used, making leak identification much easier.
This test can detect leaks as small as 0.1 gallons per hour (about a slow toilet flapper drip). Takes 2 hours total. Best done in the early morning when irrigation systems are typically off and household water use is low.
Turn off all faucets, dishwasher, washing machine, ice maker. Put a note on toilets: "Do not flush." Disable irrigation controller (if applicable). Do not run any plumbing for the next 2 hours.
Open your meter box and write down the exact reading — including all digits and the position of the sweep hand (for analog meters, note the fractional reading to nearest 0.1 gallon). Take a photo for reference. Time-stamp your reading. Note: the low-flow indicator (triangle or star) position on analog meters.
Do not use any water in the home for exactly 2 hours. This includes toilets, sinks, outdoor hose bibs, and irrigation. Walk through the home and listen for: running water sounds in walls (slab leak), toilet tank hissing (flapper leak), dripping sounds. Mark down any sounds and their location.
After 2 hours, read the meter again in the same way. Calculate the difference: End reading minus Start reading. If the reading is identical — no significant leak detected. If it changed: even 0.1 gallon over 2 hours = ~1,000 gallons per year of water loss.
0 gallons in 2 hours = no detected leak. <1 gallon in 2 hours = very small leak — check toilet flappers first (dye test). 1–5 gallons in 2 hours = moderate leak — systematically check toilets, outdoor hose bibs, irrigation valves. 5+ gallons in 2 hours = significant leak — consider slab leak or main line leak. Call a plumber.
Toilet flappers are the #1 silent leak source in FL homes — a worn rubber flapper wastes 20–200 gallons per day without any visible dripping. The dye test takes 5 minutes:
Add 5–10 drops of food coloring (or a dye tablet — your FL water utility may offer them free) to the toilet tank. Do NOT flush. Wait 15 minutes. Look in the bowl — if color appears without flushing, the flapper is leaking. Fix: replace the flapper ($5–$15 DIY) or call a plumber. FL's hard water (calcium deposits) accelerates rubber flapper deterioration — most FL homeowners should replace flappers every 3–5 years rather than waiting for visible leaks.

On this page, Florida water meter leak estimates run about $4,000-$15,000, depending on home size, materials, and project scope. Use the calculator above for a Florida-specific estimate.
Pricing depends on the size and layout of your home, the pipe materials and fixtures you choose, your Florida region and local labor rates, and permit fees. Work that is more complex or harder to access generally costs more.
In Florida, minor maintenance may be DIY, but anything beyond that generally calls for a licensed plumber, and many jobs require a permit and inspection. When a permit, or your main water or drain lines are involved, hire a Florida-licensed plumber.
It depends on the cause and your specific policy. Sudden, accidental damage is more often covered than gradual wear-and-tear or maintenance - confirm the details with your insurer.
Timelines depend on scope - many routine jobs take a few hours to a day, while larger projects run longer. Your licensed plumber can confirm after assessing your home.
