Palomar Mountain's Unique Environment
Palomar Mountain rises in northern San Diego County, offering stunning views from the Coastal Range to the desert. This elevation creates a mountain climate that requires careful planning for well systems.
Climate and Seasonal Considerations
Palomar Mountain's weather presents distinct challenges:
- Winter freezing: Regular temperatures below freezing from November through March
- Snow events: Several significant snowfalls typical each winter
- Access roads: S6 and S7 may close during winter storms
- Temperature swings: Large daily variations, especially in spring and fall
- Summer thunderstorms: Monsoon season brings lightning and power outages
❄️ Freeze Protection is Essential
Every Palomar Mountain well needs proper winterization. We help cabin owners prepare their systems before cold weather arrives—don't wait until the first freeze!
Geology and Groundwater
Palomar Mountain's geology affects well drilling and production:
- Gabbroic rock: The mountain is composed of unique gabbroic formations
- Fractured aquifers: Water flows through cracks and fissures in bedrock
- Good recharge: Significant precipitation supports groundwater
- Variable yields: Production depends on intersecting fracture zones
- Quality filtration: Natural rock filtration produces clean water

🛡️ Tank Protection
Insulated tank blankets or heated enclosures for pressure tanks.
Seasonal Cabin Shutdown
Many Palomar Mountain properties are seasonal retreats. For cabins not used in winter:
- Complete drain-down: Remove all water from the system
- Compressed air blowout: Clear residual water from lines
- Pump protection: Proper shutdown procedures
- P-trap antifreeze: Protect drain traps from freezing
- Spring startup service: Restore system when you return
