Where the stain points
| Stain location | Likely source |
|---|---|
| Walls, sidewalks, cars near sprinklers | Irrigation well water |
| Pool deck and screen enclosure | Sprinkler overspray or well water used to top off |
| Toilets, sinks, laundry | Drinking well, or old plumbing |
| Brief brown water from the tap | Main flushing or repairs nearby |
Irrigation choices in Pompano Beach
Pompano Beach is unusual: the city operates OASIS, a reuse water system for lawn irrigation, and single-family properties can connect through its program. Reuse water is highly treated wastewater; the city notes it has more nitrogen and phosphorus than drinking water. Homes that irrigate from a private well instead pump untreated aquifer water, and that is where iron staining usually starts. The city publishes a reuse map so you can see whether reuse lines reach your street.
Brown water from the tap
The city FAQ says brown or yellow water can happen when distribution work and main flushing are happening in your area. Run cold water until it clears. If it persists, call the city. Persistent rusty water on the hot side only can point to the water heater.
Treatment options
- Irrigation well: iron filtration or oxidation sized for the pump's flow, or switching the irrigation source.
- Drinking well: a well water system configured from a full well test; iron often comes with sulfur.
- Old plumbing: a plumber's assessment; Pompano Beach's online map shows your recorded service line materials.
The Department of Health notes iron bacteria are not known to cause disease, but can cause stains, tastes and odors.
Preventing new stains
- Aim sprinkler heads away from walls, walks, fences and cars.
- Water during allowed hours: the city prohibits irrigation from 10 a.m. to 4 p.m.; reuse customers may water any day outside those hours.
- Install a backflow preventer where required; the city requires one on irrigation services.
- Check the well's water once a year if you see new staining; iron levels can change.
Cleaning old stains is a separate job. A treatment system stops new ones from forming but won't remove what's already on the stucco.
Testing the right water
Jorge tests the water that is making the stain, which may be a hose bib on the irrigation line rather than your kitchen tap. Iron, pH and hardness decide the approach. Call, text or WhatsApp (305) 793-5974.
