Common Pump Issues in San Marcos
Wells in San Marcos typically range from 250-450ft with geology consisting of sedimentary and volcanic formations. This means pumps here face unique challenges:
- Pump depth settings: Most San Marcos wells require pump settings between 250 and 450ft, which means your pump is working hard to lift water from deep underground.
- Typical yields: San Marcos wells produce 5-15 GPM, which affects pump sizing and horsepower requirements.
- Local water quality: moderate hardness (8-14 grains), limited wells - mostly municipal — these contaminants can cause premature pump wear and motor failure.
