The point to understand
Different surfaces and measurement methods can produce different results. A pattern of readings across comparable areas is usually more informative than one isolated value.
Put it into practice
Keep the reading location, surface material and surrounding observations together. Relate the pattern to weather, normal use and possible plumbing routes.
Keep the limits in view
A high reading does not name the water source. Suitable system checks are needed before treating the result as evidence for a pipe repair.
