Determine the horsepower of your sump pump (probably 1/2 or 1/3).
Step2
Calculate the wattage requirement to start the pump. A 1/2 hp pump requires 2,150 watts to start and a 1/3 hp pump requires 1,300 watts. The wattage requirement to operate the pump after start-up is approximately 60 percent of the total.
Step3
Consider whether you want your generator to run other appliances during a power failure. Calculate the wattage requirements to run these appliances as well. A typical refrigerator requires about 2,200 watts to start and about 700 to run thereafter. Lights require the wattage of the bulb.
Step4
Purchase a generator of sufficient wattage for your needs.
Step5
Have a qualified electrician install a transfer switch if you intend to use the generator for backup power to the house. This is not necessary if you intend to simply plug the pump and any other appliances into the generator manually as needed.
Step6
Keep sufficient fuel on hand to operate the generator.
Step7
Follow all operating and safety instructions that come with the generator.
Tips & Warnings
You do not need a generator sufficient to start everything simultaneously. You can manually hook up the refrigerator and lights after the pump has started.
Generators have a maximum and a rated output. The maximum output should never be sustained for more than 30 minutes, so you can figure on the maximum for starting appliances, but not for sustained operation.

There are basically two types of generators: portable and standby. A standby generator is an ideal solutions because it (a) automatically starts whether you're home or not and (b) powers additional appliances during a power outage.

Buy one of the hand-cranked (fuel) transfer pumps (about $100.00). Attach the needed length of pick-up hose (garden hose will work) to reach mid-to-bottom of the sump-well. Attach the discharge (garden hose again) long enough to reach out a basement window.
