Match the stain to the source
| Where you see it | Likely source | Usual fix |
|---|---|---|
| Walls, sidewalks, fences near sprinklers | Irrigation well | Redirect heads; irrigation-specific iron treatment |
| Toilets, sinks, laundry, on a well | Drinking well | Iron removal stage in a well system |
| One fixture, or after water sits, older home | Corroding pipes or fittings | Plumbing repair |
| Hot water only, brownish | Water heater sediment or corrosion | Flush or service the heater |
Why county water is usually not the cause
PBCWUD's 2025 report says the Western Region draws from the Floridan Aquifer and treats the water at its western plant before it enters the pipes. The utility targets a pH of 7.8 to 8.5 in the West, which it describes as one way it minimizes corrosion. Discoloration can still happen briefly after main breaks or hydrant flushing; if your cold water runs orange for a short time and then clears, that is a different situation from steady staining.
Wells: iron that appears after the water dries
Dissolved iron in groundwater is clear coming out of the ground and turns orange when it meets air. That is why stains show up where water evaporates: around sprinkler spray, at the toilet waterline, under hose bibs. Removing it from house water usually means oxidizing the iron and filtering it out, ahead of any softener or RO membrane that iron could foul. Living Water configures its well water system from the test.
Irrigation wells
Treating a high-volume irrigation well is a separate project from treating house water. The cheapest first step is aiming sprinkler heads away from walls, fences and paved areas. For persistent staining, ask about irrigation-specific iron treatment.
Cleaning existing stains
Treatment stops new stains; it does not remove old ones. Use a rust-stain cleaner suited to the surface and test a small area first, especially on painted stucco and stone.
Some stains are deposits on porous surfaces like pavers and stucco that need repeated treatment. For pool decks and screens, check with the product manufacturer before using acid-based cleaners.
