What does that meter change mean?
Enter a measured volume increase and the elapsed time. All calculations stay in this browser.
This extrapolates a constant rate. It may include normal water use and is not a diagnosis of leakage.
How to use the result
Use a safe, accessible meter reading and record the units displayed. Enter the difference between the later and earlier reading, not the entire cumulative meter total. The time interval must be greater than zero.
For example, a measured increase of 2 US gallons in 10 minutes is 0.2 gallons per minute, equivalent to 288 gallons over 24 hours if the rate stayed constant. It could include normal equipment use. Do not label the entire amount as lost water.
Keep the meter check observational
Do not operate utility controls, fire-system valves or unfamiliar equipment. Ask the responsible operator if the meter cannot be read safely or its units are unclear. For a shared meter, note that other users may contribute to the reading.
The high-water-bill checklist explains how operating schedules and reading periods affect interpretation. For an unexplained supply-side pattern, review water-line leak investigation.
Bring the observation to a provider
Share the two readings, times, units and any equipment known to be running. A provider can decide what further checks are appropriate. A calculator cannot identify the source or determine whether the system should be isolated.

Common questions
Is the estimated daily volume a leak amount?
No. It extrapolates an observed rate and may include normal use. Only a suitable investigation can help explain the cause.
Are my readings saved or sent?
No. This calculator works locally in your browser and does not submit or persist the input. Reloading clears it.
