How to Fix Rusty Well Water
Experiencing this problem right now? Call us for immediate assistance.
When your water comes out looking like rust, it's not just unappealing—it stains everything it touches. Rusty well water is typically caused by dissolved iron that oxidizes when exposed to air. While not usually a health hazard, it makes water unusable for laundry, damages fixtures, and affects taste.
Common Causes
- Dissolved Iron in Groundwater: The most common cause. Iron occurs naturally in many aquifers and dissolves into groundwater.
- Corroding Well Casing: Older steel well casings rust over time, shedding iron particles into your water.
- Corroding Pipes: Galvanized steel pipes rust from the inside, adding iron to water that may have started clear.
- Iron Bacteria: These naturally occurring bacteria metabolize iron and create rusty, slimy deposits.
- Sediment Disturbance: Stirred-up sediment from pump work or heavy water use can temporarily increase rust.
- New Water Source: Changes in the aquifer can introduce water with higher iron content.
Warning Signs to Watch For
- Orange, red, or brown water color
- Staining on toilets, sinks, and tubs
- Rust stains on laundry (especially whites)
- Metallic taste
- Clogged fixtures or appliances
- Brown slime in toilet tanks
How to Fix This Problem
1. Test Your Water
Determine iron levels (measured in ppm or mg/L) and whether it's dissolved (clear water) or particulate (already colored). Treatment depends on type and concentration.
2. Sediment Filter for Particles
If rust particles are visible, a sediment filter captures them. This won't help with dissolved iron that oxidizes later.
3. Oxidizing Filter
For dissolved iron, oxidizing filters (using air injection, chlorine, or greensand) convert dissolved iron to particles for removal.
4. Water Softener
For low iron levels (under 2-3 ppm), water softeners can remove iron. Higher levels overwhelm conventional softeners.
5. Replace Corroding Components
If the rust source is well casing or pipes, filtration treats the symptom but replacement solves the problem.
When to Call a Professional
While some minor issues can be addressed by homeowners, well system problems often require professional diagnosis. Call Southern California Well Service if:
- You're not comfortable working with electrical systems
- The problem persists after basic troubleshooting
- You notice multiple symptoms at once
- Your well is over 10 years old and hasn't been serviced
We offer same-day emergency service throughout San Diego, Riverside, and San Bernardino counties.
Frequently Asked Questions
Is rusty well water safe to drink?
Iron itself isn't harmful and is an essential nutrient. However, iron bacteria or other contaminants may accompany high iron. Testing is recommended.
Will a water softener remove rust from water?
Standard softeners can remove low levels of iron (typically under 2-3 ppm). Higher concentrations require dedicated iron removal systems.
How much does it cost to treat rusty well water?
Treatment costs range from $500-1,500 for basic filtration to $2,000-4,000+ for whole-house oxidizing systems.
Why did my well water suddenly turn rusty?
Sudden changes often indicate sediment disturbance, casing corrosion, or changes in your water source. Recent pump work or drought can trigger this.
