Quick answer: A sudden spike in your water bill with no change in habits almost always means a hidden leak — most often a running toilet, a dripping fixture, an irrigation leak, or a slab leak under your foundation. The fastest way to check: turn off all water and watch your water meter. If it keeps moving, water is escaping somewhere. Finding and fixing it early can save hundreds of dollars a month.
The most common causes of a high water bill
- A running or leaking toilet — the #1 hidden water waster; a silent flapper leak can waste thousands of gallons
- Dripping faucets or fixtures — small drips add up fast over a month
- Irrigation/sprinkler leaks — cracked lines or stuck valves run water underground
- A slab leak — a pipe leaking under your foundation (common in Florida slab homes)
- Water heater or supply line leaks
- Higher seasonal use — extra irrigation or guests can explain a modest increase
How to find the leak yourself
- The meter test: turn off every faucet and water-using appliance, then check your water meter. If it is still moving, you have a leak.
- The toilet test: add a few drops of food coloring to the tank. If color appears in the bowl without flushing, the flapper is leaking.
- Check for damp spots on floors, walls, or in the yard.
When to call a professional
If the meter test shows a leak but you cannot find the source, it is likely hidden in a wall, underground, or under the slab. A licensed plumber uses electronic leak detection to pinpoint it without tearing up your home — so you fix only what is needed.
