Combine measured losses from two fixtures
A resident measures 0.08 and 0.12 L/min independently at two fixtures running continuously. They compare the combined loss with the remaining flow after fixing the higher-rate fixture.

What the comparison shows
Repairing the higher-flow fixture first removes 1,728 L from this ten-day model. The remaining fixture still contributes measurable loss.
Assumptions and limits
Add rates only for overlapping durations. A whole-home measurement may already include both leaks.
