Keep Your Well Pump Running When the Power Goes Out
Backup generators for rural properties and well water systems throughout Western Chicagoland — properly sized to handle motor starting surges plus whole-home load.
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 rural 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.
½ HP Pump
- Starting: 2,100-2,400W
- Running: 700-800W
- Minimum: 10-13 kW generator
¾ HP Pump
- Starting: 3,000-3,500W
- Running: 1,000-1,200W
- Minimum: 13-16 kW generator
1 HP Pump
- Starting: 3,600-4,200W
- Running: 1,200-1,500W
- Minimum: 16-18 kW generator
1½ HP Pump
- Starting: 5,400-6,300W
- Running: 1,800-2,200W
- Minimum: 18-22 kW generator
2 HP Pump
- Starting: 7,200-8,400W
- Running: 2,400-3,000W
- Minimum: 22-26 kW generator
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 rural Illinois. Pump sits deep in well casing below water line.
- Higher starting watts — motor works harder pushing water up
- Typical depth: 100-300 feet in Western Chicagoland
- 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 Rural Western Chicagoland
Rural properties in Yorkville, Oswego, Geneva, Batavia, and surrounding Kane and Kendall County communities often rely on private well water systems. During ComEd outages from ice storms, thunderstorms, and high wind events, these homes lose water access when power fails — no toilets, showers, drinking water, or irrigation. For 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.
Frequently Asked Questions
What size generator do I need for a well pump?
Generator sizing depends on pump horsepower and type. A ½ HP submersible pump needs a 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. These sizes account for the 2-3x starting wattage surge when the 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 a well pump, central air conditioning, and other home systems simultaneously during outages. A 22 kW Generac Guardian powers most rural homes including a 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) and generator capacity. The well pump circuit connects through the transfer switch like any other 240V circuit.
Can generators run well pumps on propane in rural areas?
Yes. Generac generators operate well pumps using propane fuel where natural gas isn't available (common in rural Yorkville, Oswego, and outer Kane/Kendall County). Typical installation includes a 250-500 gallon propane tank providing days to weeks of runtime during extended storm outages.
How long does well pump generator installation take?
Well pump generator installation for rural 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, local electrical permit, propane tank delivery if needed, generator installation, and inspection.
What Drives Well Pump Generator Scope
Sized to your well pump plus the home load — the variables we assess on a site walk.
- Well pump horsepower and starting-watts headroom (submersible pumps pull 2–3× running watts at startup)
- Other loads on backup: whole house, essentials only, outbuildings, livestock water
- Fuel type: propane tank size for target runtime on rural properties without natural gas
- Panel capacity and whether a service upgrade is required first
- Soft-start controller option to reduce required generator size
Propane tank installation is scoped separately. Sizing is based on your well pump nameplate. Request a rural assessment.
Backup Power for Rural Well Systems
Rural Western Chicagoland properties depend on private wells for water supply. When power fails during winter storms or severe thunderstorms, 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 Yorkville, Oswego, Geneva, and rural Batavia include load calculations specific to your well pump motor. For larger agricultural operations, see our ranch and agricultural generator services.
