Common Well Problems in San Diego County
San Diego's unique climate and geology create specific challenges for well owners. Understanding these common issues helps you recognize problems early and know when to call for service.
Hard Water Issues
San Diego is notorious for extremely hard water. Our mineral-rich geology means most well water contains high levels of calcium and magnesium. Signs include:
- White scale buildup on fixtures, showerheads, and appliances
- Soap that doesn't lather well
- Stiff, dingy laundry
- Spots on dishes and glassware
- Dry, itchy skin and hair
- Reduced water heater efficiency
- Shortened appliance lifespan
Solution: Water softener installation. See our hard water solutions guide.
Drought & Low Water Yield
California's periodic droughts affect groundwater levels, and San Diego wells can experience:
- Decreased water production (lower GPM)
- Air spurting from faucets as water level drops
- Well running dry during peak usage
- Need to deepen wells or drill new ones
- Pump damage from running without sufficient water
Solutions: Storage tank installation, well deepening, or drilling a new well. See our well running dry guide.
Pump Failures
Well pumps in San Diego often fail due to:
- Sediment and sand: Abrasive particles wear impellers faster
- Hard water scale: Mineral buildup reduces efficiency and causes overheating
- Age: Most pumps last 8-15 years with proper conditions
- Electrical issues: Power surges, lightning, and voltage problems
- Running dry: Low water conditions damage pumps quickly
Solution: Professional diagnosis and pump repair or replacement.
Water Quality Problems
Common water quality issues in San Diego wells include:
- Iron/manganese staining: Red, brown, or black stains on fixtures
- Sulfur odor: "Rotten egg" smell in some areas
- Bacteria contamination: Often after flooding or septic issues
- Nitrates: Common in agricultural areas
- Arsenic: Naturally occurring in some East County areas
Solution: Water testing followed by appropriate treatment.
Pressure Problems
Pressure issues affecting San Diego well systems:
- Low pressure: Failing pump, tank problems, or pipe restrictions
- Fluctuating pressure: Waterlogged pressure tank or check valve issues
- Pressure tank cycling: Tank losing pre-charge or bladder failure
- Pump short-cycling: Rapid on-off cycling that damages equipment
Solution: Diagnosis of pressure tank and pump system.
