Keep Your Well Pump Running When the Power Goes Out
Backup Generators for Rural Properties & Well Water Systems
Why Well Pump Owners Need Backup Generators
Don't lose water access during power outages
Never Lose Water
Keep well pump running during power outages for water, toilets, showers, and irrigation
Handles Starting Watts
Properly sized generators handle 2-3x running watts needed for pump motor startup
Whole House + Well
Single generator powers well pump plus all essential home systems simultaneously
Livestock Protection
Critical for ranch/farm properties with livestock water troughs and barn systems
Automatic Operation
Generator starts automatically when power fails - well water available immediately
Soft Start Compatible
Works with soft start motor controllers to reduce starting wattage requirements
Well Pump Power Requirements
Generator sizing depends on well pump HP and starting vs running watts
Generator must handle starting watts (2-3x running watts) plus other home loads. We calculate exact requirements during free assessment.
Submersible vs Jet Pump Considerations
Submersible Pumps
Most common in East County. Pump sits deep in well casing below water line.
- •Higher starting watts - motor works harder pushing water up
- •Typical depth: 100-400 feet in East County
- •Requires larger generator (usually 16-24 kW)
- •Soft start controllers can reduce surge requirements
Jet Pumps
Less common in rural areas. Pump sits above ground in pump house or basement.
- •Lower starting watts - easier motor startup
- •Works best for wells under 100 feet deep
- •Can use smaller generator (13-18 kW often sufficient)
- •Easier to service since pump is accessible
Well Pump Generators for East County Rural Properties
Most Julian, Ramona, Descanso, Pine Valley, Boulevard, Campo, and rural Alpine/Jamul properties rely on private well water systems. During SDG&E PSPS events and storm-related outages, these homes lose water access when power fails - no toilets, showers, drinking water, or irrigation. For ranch and agricultural properties with livestock, extended power outages create dangerous situations with animal water troughs running dry. A properly sized Generac home standby generator automatically powers well pumps (plus whole-house systems) during outages. We specialize in generator installation for rural properties with submersible and jet pump systems, calculating exact wattage requirements for motor starting loads and coordinating propane tank installation where natural gas isn't available.

Well Pump Generator Questions
What size generator do I need for a well pump?
Generator sizing for well pumps in East County depends on pump horsepower and type. A ½ HP submersible pump needs minimum 10-13 kW generator; ¾ HP needs 13-16 kW; 1 HP needs 16-18 kW; 1½ HP needs 18-22 kW; 2 HP needs 22-26 kW. For detailed sizing calculations and pump-specific recommendations, see our well pump generator sizing guide (/guides/generator-size-for-well-pump). These sizes account for 2-3x starting wattage surge when pump motor engages. We provide free load calculations specific to your pump nameplate data.
Can a generator run a well pump and air conditioning together?
Yes, properly sized Generac generators (typically 22-26 kW) can power well pump, central air conditioning, and other home systems simultaneously during outages. Generator must handle combined starting watts when well pump and AC compressor cycle on together (worst-case scenario). For complete home sizing calculations, see our generator sizing guide (/guides/what-size-generator-do-i-need). A 22 kW Generac Guardian powers most rural East County homes including 1 HP submersible well pump, 3-4 ton central AC, refrigerator, lights, and essential appliances.
Do I need a special transfer switch for well pumps?
Well pumps typically connect to standard whole-house automatic transfer switches - no special equipment required. Transfer switch must be rated for your electrical panel size (usually 200-amp for rural properties) and generator capacity. For detailed transfer switch information, see our transfer switch types guide (/guides/transfer-switch-types-explained). The well pump circuit connects through transfer switch like any other 240V circuit. We design transfer switch configuration based on your well pump location, electrical panel setup, and desired backup coverage.
Can generators run well pumps on propane in rural areas?
Yes, Generac generators operate well pumps using propane fuel where SDG&E natural gas isn't available (most of Julian, Descanso, Pine Valley, Boulevard, Campo, and rural Alpine/Ramona/Jamul). For help choosing between fuel types, see our propane vs natural gas generators guide (/guides/propane-vs-natural-gas-generators). Typical installation includes 250-500 gallon propane tank providing days/weeks of runtime during extended PSPS or storm outages. We coordinate propane tank sizing and service provider setup as part of turnkey installation.
How long does well pump generator installation take?
Well pump generator installation for rural East County properties takes 1-2 days once permits and fuel service are ready. Complete process typically takes 3-5 weeks including: free assessment with well pump load calculation (same day), San Diego County electrical permit (3-7 days), propane tank delivery if needed (1-2 weeks), generator installation (1-2 days), county inspection (3-5 days). For complete permit requirements, see our generator permits guide (/guides/generator-permits-san-diego-county). Rural locations may require additional time for propane service coordination.
Will a generator protect well pump from power surges?
Yes, Generac home standby generators provide clean, stable power that eliminates voltage fluctuations and surges that can damage sensitive well pump motors and pressure switch controls. When utility power experiences brownouts, spikes, or dirty power conditions common during storm events, generators provide consistent voltage and frequency. Many rural East County well pump failures result from power quality issues rather than pump aging. Automatic transfer switch also isolates your well system from grid during generator operation, providing additional protection from utility-side electrical problems.

Backup Power for Rural Well Systems
Rural East County properties depend on private wells for water supply. When power fails during PSPS events, you lose water for drinking, bathing, toilets, livestock, and irrigation. A properly sized generator keeps your well pump running throughout any outage.
Our generator installations for well properties in Julian, Boulevard, Campo, and rural Ramona include load calculations specific to your well pump motor. For larger agricultural operations, see our ranch and agricultural generator services.
