Need a Generator for a Sump Pump which type to get?

I would like to a Generator for my sump pump. The generators I am looking at are 1000 watts. I also see some that are 1000 Watts are brushless and some arent. Both say they put out 1000 Watts but have different AMPs one is 8.5 amps and the other is 15 amps. The sump pump I am using 120 V and says Circuit Requirements 15amps. I guess that means I should go for the one that says 15amps? Thanks!

You want it incase the power goes out? If you have city water look at

What does the pump use, read the plate on it, you need to figure in surge startup needed, about 2x run power or more

The sump pump is for pumping out my basement to keep it from flooding. So incase the power goes it it wont flood.

Not when the water decides to come in when I am a sleep. We have not lost power when we do happen to get flooding in the basement but better safe than sorry. If we did lose power when it did flood we would have swimming pool ha ha a

Do you have city water, then get a water powered pump, are you going to be home when the power goes out to start the gen. Gas powered pumps are also an option.

If you do not know the startup amperage of your pump, then 4000 watts to be safe. See bottom of following...

Measure the actual current the sump pump uses. If it's no more than

12 amps, then the 15 amp gen should be fine. But if you're buying a gen for longer outages, you might want to consider one that's large enough to run some other critical loads too. As part of this, you'll also need a battery backup to run the sump until someone can get there to start up the generator. Having the battery backup will also give you flexibility with the generator. The generator can be charging the battery while the sump pump is running. This would allow you to either turn off the generator periodically, or else disconnect the sump pump and use the generator for other critical loads, eg refrigerator. If you go that route, be sure to factor in the current reqts of the charger.

Ransley's idea of the water powered pump is a viable one too. It depends on if you have municipal water and what the cost of it is. You'd need to calculate how much water you need to remove, how much city water it takes to do that, and how much it could cost.

Good points, but water is a hell-of-a-lot cheaper than gasoline.

Probably the very cheapest way to go is an insurance policy to cover the damage from a power outage.

I never saw a 15 amp pump, a 1/3hp use 2.1-3 amp, 1/2hp 3.5-5 amp. A

1/2 hp which is bigger than I have pumps at 6ft 50 gpm, 3000 gallons an hour, he does need to figure in startup surge load but the idea of a gen for only a mythical 15a pump isnt what I would do. A 15 amp pump might pump 350,000 gallons a day, isnt that bigger than an olympic pool.

A horse power is 748 watts, so a thousand watt generator oughta do it. Of course, while you have it running. You ought to plug in a lamp, and give the refrigerator a turn on the generator every few hours. Most 1,000 watt generators will do all that. Just need to have plenty of gas and oil on hand, and take turns what gets plugged in.

748 watts is not what a 1 hp sump conumes. If what you said on hp to watts was relavent to a pump then how do you explain a 1/2hp Zoeller pump consuming 5a, 600w. You cant use Hp to Watts. Even if you were correct you make no calculation for reserve power to get the pump started moving, called surge load, and for a pump starting a big head of water 2.5 times might do it. Now who has a 1hp sump pump in their basement?

Nah, an Olympic pool holds 648,000 gallons. Not sure if that's U.S., Imperial, or Approximate.

Might be Olympic gallons?
