The problem: the meter moves even when everything is off
You shut off every faucet, the dishwasher is quiet, and no one is showering. But the water meter still creeps forward. That usually means water is flowing somewhere you cannot see.
The good news: you can confirm the issue and narrow it down in a few simple steps, without any tools.

The short answer
If the meter moves with all water off, there is likely a leak. The meter is the simplest truth source because it only moves when water is flowing.
Confirm the meter is moving
Many meters have a small leak indicator or triangle that spins with even tiny flows. Use this guide if the dial is unfamiliar: how to read a water meter.
Watch the indicator for one to two minutes. If it moves, the meter is detecting flow. For a deeper explanation of that indicator, see water meter leak indicator explained.
Isolate indoor vs outdoor
Turn off the main house shutoff valve and check the meter again. If the meter stops, the leak is inside the house. If it keeps moving, the leak is likely between the meter and the house or in an outdoor line.
If your irrigation has a separate shutoff, close it and recheck. This helps isolate sprinkler or drip line leaks.
Common leak culprits
- Running toilets: the most common indoor leak.
- Faucet drips: small but constant flow.
- Water softeners: stuck regeneration cycles.
- Irrigation valves: slow leaks in sprinkler zones.
- Outdoor spigots: damaged anti-freeze valves.

What to do next
If you confirm a leak, document the meter movement and note the time. That helps if you need to contact your utility or a qualified plumber.

Common misconceptions
- "The meter is broken." It usually reflects real flow, even tiny leaks.
- "Small leaks do not matter." A slow leak adds up over a month.
- "No sound means no leak." Many leaks are silent.
