CHECKLIST & OBSERVATION SHEET

Water Meter Leak Check

Comparing meter readings while intentional water use is paused can help you investigate unexplained flow. It does not identify a damaged pipe or determine a repair.

Check access before starting

Read a meter only when it is safely accessible and your utility permits access. Do not force a cover, reach into an unsafe box or operate a utility-owned valve. Ask the utility for help if access or the display is unclear.

For a shared meter, coordinate with the property manager. Water use in another unit can affect the reading.

Make a useful comparison

1. Identify the units. Record the complete display, including decimal places, and whether the meter measures gallons, cubic feet or another unit.
2. Pause intentional use. Check taps, irrigation schedules and equipment that can start automatically, including ice makers and softeners.
3. Record the starting time and reading. Note what was paused and what might still use water.
4. Compare later. EPA WaterSense suggests checking before and after two hours without water use. Record the actual elapsed time.
5. Record exceptions. If water was used or an automatic cycle ran, note it. Repeat the observation when practical rather than treating a mixed-use period as a clean test.

Understand the limits

An increased reading means water passed through the meter. Account for known uses first. If the movement remains unexplained, ask the utility or a qualified professional what investigation is appropriate.

A still display during one check does not rule out intermittent water loss or a change too small for the display to show. Visible moisture may also require investigation outside the metered supply. Avoid digging or opening finishes based on a reading alone.

Next, use the appointment preparation guide or compare your bills with the water-use worksheet.
