How an uncertain leak start date changes the estimate

The measured flow may be clear while the start date is not. At an illustrative 0.05 L/min, compare fourteen days of loss with twenty-one days; household size does not change either calculation.

0.05 L/min × 1,440 min/day × 14 days = 1008 L. Divide by 1,000 for m³, then multiply by 4 for USD 4.03.

What the comparison shows

An extra week adds 504 L. Treat the two estimates as possible bounds only if the assumed dates bracket the true start.

Assumptions and limits

Household size does not multiply the leak. The meter check cannot identify which fixture caused the loss.
