Read the pattern
| What you see | Likely source |
|---|---|
| Discolored water first thing in the morning, clears in a minute | Iron or galvanized pipe inside the house |
| Rusty hot water only | Water heater sediment or tank corrosion |
| Brown water at many taps, for hours, across the block | Main work, a break, or hydrant flushing |
| Orange streaks on walls, pavers or the driveway | Irrigation water from a well |
| Orange ring in the toilet bowl | Iron from plumbing or a heater, worse with low use |
Corrosion control and older plumbing
WASD adds a phosphorus compound at its plants to reduce corrosion in the distribution system and in home and business plumbing. That helps, but it cannot undo pipes that are already corroded. In older homes, water that sits overnight in iron or galvanized pipe picks up rust and comes out discolored at first. The fix is plumbing: replacing the worst sections. Opa-locka's report also advises that when water has been sitting for several hours, running the tap for 30 seconds to 2 minutes before drinking or cooking reduces the potential for lead exposure from plumbing, a good habit in any older house.
Hydrant flushing weeks
WASD's fact sheet for its annual chlorine conversion, posted by the city, says customers may notice temporary discoloration as water rushing out of hydrants removes sediment from pipes, and occasionally slightly lower pressure. In 2025 that period was October 13 to 26. Run cold water until it clears and skip white laundry until then. If the water does not clear, call Public Works at 305-953-2828.
Irrigation wells
A shallow well for sprinklers delivers untreated groundwater. Dissolved iron oxidizes in air and sunlight and leaves orange streaks wherever spray lands. Miami-Dade's irrigation rules apply to wells too: two days a week by address (odd numbers Wednesday and Saturday, even numbers Thursday and Sunday), before 10 a.m. or after 4 p.m. Iron filtration or a metered treatment on the irrigation line is what stops new stains; existing ones need a rust remover tested on a small area first.
What Jorge tests
- Iron in hot and cold tap water.
- Iron and pH in well water, if you have one.
- Hardness and chloramine, which shape what treatment fits.
If the source is your pipes, he will say a plumber is the right call. Call, text or WhatsApp (305) 793-5974. See also well water systems.
