Measure a leak before pricing it
A visible drip rate is hard to convert into volume because drops vary in size. A measured collected volume over a known duration is a stronger starting point. Do not handle unsafe plumbing or electrical areas.
From measured flow to cost
If a container collects 0.6 liters in three minutes, the measured rate is 0.2 L/min. Over ten days, that is 0.2 × 60 × 24 × 10 = 2,880 L, or 2.88 m³. At an illustrative USD 3.00/m³, the water charge is USD 8.64.
Variable flow and excluded costs
Measure more than once if the flow varies. A leak estimator assumes a constant average flow for the entered duration. The result excludes repairs and property damage, which cannot be inferred from volume.
Verify the repair
After a repair, compare meter readings over similar intervals. If the meter still moves while all intended use is off, seek appropriate local plumbing advice. Do not use a cost estimate as a reason to delay a necessary repair.
The start date is another assumption
Today’s flow does not establish when a leak began. Record the earliest evidence and last known normal reading, then price plausible durations separately. Use active time with active flow, or average flow with total elapsed time. Combining intermittent active flow with every minute of a month exaggerates volume.
