Miami-Dade High Water Bill Investigation, Leak Adjustment, Pool Credit and Payment Extension

What to Check Before Calling About a High Miami-Dade Water Bill
Miami-Dade says high bills are often caused by leaks that are not visible, including underground or concealed leaks. Common household causes include worn toilet flappers, dripping faucets, showerheads and other leaking valves.
| High-bill clue | Possible reason | First check |
|---|---|---|
| Usage suddenly increased | Hidden leak, extra guests, pool filling, pressure cleaning, hose left on or yard work. | Compare usage history and inspect toilets, faucets, hoses and irrigation. |
| Wet lawn or unusual moisture | Underground line leak or irrigation problem. | Check yard, meter box, service line path and irrigation valves. |
| Toilet runs silently | Worn flapper or internal toilet leak. | Use a dye test and listen for refilling when no one flushed. |
| Meter appears active with fixtures off | Leak somewhere on customer side. | Turn off all fixtures and follow Miami-Dade’s meter leak detection steps. |
