    A High Water Bill and Possible Leaks

    A sudden spike in your water bill can signal a leak — or just a change in usage. Knowing how to compare usage and check the meter safely helps you tell the difference.

    Before assuming a leak, compare your usage to prior periods and observe the meter with everything off. These safe, non-invasive steps help confirm whether a leak is likely before any tracing begins.

    Separate Cost From Consumption

    A higher bill isn't always a leak. If your metered consumption is unchanged but the cost rose, review rate changes, fees, billing-period length, or estimated readings with your utility before assuming a leak. Those billing factors can raise a bill without any change in water use.

    An unexplained increase in water consumption — more water actually moving through the meter — is the clue that points toward a leak and is worth investigating.

    A Safe Meter Observation

    Turn off all fixtures and appliances that use water, including automatic users such as irrigation systems and dishwashers, then observe whether the meter continues to advance. Meter movement after accounting for those users is a clue, not a final diagnosis — but it suggests water is going somewhere and a professional can trace it. This check requires no disassembly.

    The U.S. EPA's Fix a Leak Week is a helpful reminder to check for leaks regularly (see the EPA WaterSense Fix a Leak Week page).

    Common Leak Locations

    • Running or leaking toilets
    • Supply lines behind walls or under floors
    • Under-slab piping
    • Outdoor spigots or irrigation lines

    Water Use Higher Than Expected?

    If your meter advances with everything off, a professional can trace the leak to its source.
