Did your Coppell water bill jump unexpectedly? Here is how to diagnose whether the cause is a running toilet, irrigation leak, or hidden slab leak.

Step-by-Step Leak Diagnosis for High Water Bills
1. Toilet Flapper Test: Drop food coloring into the toilet tank; if color appears in the bowl without flushing, the flapper is leaking. 2. Water Meter Flow Indicator: Watch the meter triangle when all taps are off. 3. Irrigation Zone Inspection: Walk the yard to check for soggy valve boxes or leaking sprinkler heads. 4. Professional Electronic Detection: If fixtures and irrigation pass, a buried under-slab leak is likely present.
