Sump Pump Wattage

Sump pump requires electric power to operate. Their requirements aren’t huge but are nonetheless vital to proper operation. Of course, we should keep in mind the fact that sump pumps vary in wattage. The amount of wattage a sump pump requires will heavily depend on its strength. Let’s go over differently powered ones and check their requirements.

¼ hp sump pump

The weakest available sump pump is a ¼ hp one. While low in power, this type of sump pump are still useful. These sump pumps are capable of properly draining a basement that doesn’t face heavy flooding.

Regular level of flooding can be handled by a ¼ sump pump with no issue. They are capable of expunging up to 30 gallons of water per minute. This should do well enough in this situation.

⅓ hp sump pump

Between the quarter increase of sump pump power, we have ⅓ hp sump pump too. This type of sump pump can be considered okay for average households. These sump pumps are usually considered the lowest you’ll need to keep your house safe from flooding in case of outage.

The capabilities of the ⅓ sump pump are such that it can relocate about 42 gallons per minute. This is quite a big amount of water that can be found within our house. To cut off any risk of flooding, 42 gpm should be enough.

When we discern wattage of the sump pump, the difference can be quite important, we’ll also gain some insight into the required power of our generator. For a ⅓ hp sum pump, we will have to use 1300 watts to start the item up. After that, the sump pump of this power will require about 800 watts to run consistently. Which is a bit more than the ¼ hp sump pump and somewhat less than ½ hp sump pump.

½ hp sump pump

For most homes, ½ is the optimal and even more than enough power. The sump pumps with this level of power are capable of draining good amount of water quickly. Making them quite a tool to employ.

As expected, a ½ hp sump pump doubles the amount of water we can expunge per minute compared to ¼ one. Going all the way up to 60 gallons per minute. The usual requirement for an average homes is a ⅓ hp sump pump but considering how small the difference in price is, ½ hp one is often a better choice.

The wattage required to keep a ½ hp sump pump running is around 1000 and 1050 watts. However, it will require a higher initial surge of power to get started. This initial surge has to be around 2100 watts, double the requirement for consistent running of the sump pump.

¾ hp sump pump

Last two sump pumps whose wattage and utility we’ll cover are powerhouses meant for those who need an extra boost in keeping their basements dry. ¾ sump pump is very useful for those homes with deeper basements or homes that are located in areas with high flooding. Whether it’s a flood plain, an area with high water tables, or any other compromised location a ¾ hp sump pump will come in handy.

One of these pumps can easily provide extra pumping capacity that surpasses previous models by a decent margin. Most of these pumps are capable of pumping about 90 gallons per minute, once again a flat upgrade over the previous one.

As for wattage, ¾ hp sump pumps will require about 1500 watts. This is generalized requirement, do keep in mind different brands could have variable requirements. Always double check the item’s requirements before purchasing it or the generator meant to power the sump pump.

1 hp sump pump

Now for a real heavy duty sump pump, we have a 1 hp one. This powerful sump pump is capable of dealing with some extreme flooding. It’s not only the power and amount of water it can displace that matters, what also matters is that the pump can move the water quite far away.

Those with exceptionally deep basements or surroundings unsuited for disposal can use this pump to avoid issues with properly dumping water. The 1 hp sump pump can lift water up to 200 feet so there should be no problem with depth when relocating water even if its position is quite deep.

The sump pump does require quite a bit of wattage. In the case of using this 1 hp sump pump, you’ll need 2000 watts to consistently run it. For the sump pump to even start, you’ll require 4000 watts of initial wattage. The generator you use will need to be exceptionally powerful for these pumps with the advantage that 1 hp sump pumps will cover even the heaviest of floods.

When it comes to gallons this pump is capable of removing, it scales adequately with the other ones. Being able to empty even more water per minute with no issue.

Visible here is the variability of requirements depending on the sump pump. No matter what type or brand of generator you choose, make sure to take into account the type of sump pump you possess. Those that are more powerful will require quite potent of a surge to get them running in the first place, while also consuming a ton of energy to stay running.

Getting a sump pump that’s too powerful for your needs will incur quite a bit of extra costs. These will usually manifest in higher electricity bills and a pricier generator we’ll have to purchase to ensure this item will work as expected. Additionally, you may have that same sump pump face some issues.

Is it bad if I get too strong of a sump pump?

sump_pump_pulling_water.jpeg

Using a sump pump that is somewhat beyond our needs is usually not that problematic. A ½ hp sump pump operating instead of a ¼ hp one will scarcely affect either the basement or the sump pump in a negative manner. However, having excess power in a sump pump and having it run in a situation where it quickly dispatches water and works on empty sump can be problematic.

Our sump pump could end up starting and stopping over and over again due to lacking water to expunge. This is a situation where a sump pump could end up wasting electricity and even get worn out faster. Picking a sump pump of ample power is recommended so we can avoid premature sump pump failure.

What size generator to run sump pump and refrigerator

Although the sump pumps alone vary in consumption, from lower 1000s to 2000s of watts, Using generators that power them for something else will require quite a lot more power. Especially when other attached items have required wattage that could drain the power of the generator on its lonesome.

Refrigerators are one such item and a device we wish to keep running when outages happen. It’s frustrating to end up with a whole fridge of spoiled food, doubly so during a catastrophe. To fuel them both, we’ll need a bigger generator.

The usual required wattage will be around 3000 watts for both of these items. Usually, those types of generators will have much higher surge power as well which allows them to start and run the sump pump and refrigerator with no problem. Plus, it’s more likely they’ll have more capacity, resulting in longer support of our electrical devices. From the ones we’ve listed, Westinghouse WGen7500 is what one could employ to keep both sump pump and refrigerator running. [1]

Portable power station for sump pump

Portability of a power station can be quite important for those who wish to utilize their generator outside of it functioning as a sump pump backup. The added uses of this type of power station mean we can apply it elsewhere and even outside of our home. Those who frequently engage with DIY work may find these generators a great pick.

As an example of a potent portable power station, we have Westinghouse WGen7500. The biggest one of the generators presented here but nonetheless portable. The smaller ones like Generac and Jackery will work if you don’t need that much power in your home.

Indoor generator for sump pump

Most of our sump pump generators will end up being indoors. The bigger generators especially may be kept within our household, even in the basement itself, and provide energy to more than just our sump pump. Considering the number of devices that need to stay operational throughout outages, such as refrigerators, we are often going to reap multiple benefits from bigger generators.

By using indoors generators, we do often end up requiring a bit of extra space than more specialized sump pump backup generators. However, knowing our everyday life will be kept mostly normal with that extra source of electrical energy can be worthwhile for those who cannot afford or dislike being without electricity. Any potent generator can work as an indoor one, so most of ours fits.

Can a solar generator power a sump pump?

For greener homes, a solar generator may be a preferred method of producing and utilizing electric energy. Solar generators are especially useful for areas that have a ton of sun. Which isn’t uncommon for areas that also get sudden surges of rain which can overwhelm a basement and require a sump pump. However, are they capable of powering our sump pumps?

An average solar generator needs to be able to produce and circulate enough energy for a sump pump to work well. The requirements refer to the stored energy of a solar generator as well. Being incapable of providing good enough energy flow means our generator won’t be able to provide a working sump pump when needed.

So we need to make sure our generator is capable of fueling the sump pump both in terms of turning it on and running it consistently. With the availability of some more potent generators, this is easy to achieve. Jackery Solar Generator 1000 is one such, providing 1000 watts of running energy. If we need even more potent one, the Jackery Solar Generator 2000 can provide the required energy. [2]

Will a 1000 watt generator run a sump pump?

As we’ve seen before, the wattage of sump pumps differs depending on their power. The difference also becomes more apparent when we take into account the initial power surge required for the sump pumps to even run.

The 1000 watt generator can run a sump pump after it has already been turned on, at least the ¼ hp sump pump. However, the other sump pumps won’t even be able to run at all. The sheer amount of required wattage to both run and start a sump pump will make a 1000 watt generator unusable for this purpose.

Portable Option to Consider

By using a portable generator we are able to relocate the generator as needed. When our sump pump is safely operating, or the danger of flooding isn’t present, the generator can be used elsewhere.

Using the generator in sheds or on other floors of our house can be quite a bit useful when missing a source of energy elsewhere. In the end, it will also depend on the power and wattage of a generator.

As you may have noted, a lot of the listed best generators for sump pump are portable. Some more than the others, owing to their smaller size, but nonetheless aimed at more versatile and mobile application. To point out a few, Westinghouse WGen7500, WEN 56200i 2000-Watt, and Generac 76711 work quite well for our needs.

Compact options to Consider

The size of our generator is important. It can be almost impossible to position a generator properly inside of our basement. With all the excess items we may keep in it and the lack of proper connections between the generator and the sump pump, it’s worth using a more compact generator.

When it comes to best small generator for sump pump, Basement Watchdog or some of the other small sump pump generators will work well. There are other available ones too, Generac 76711 works exceptionally well although it requires just a bit more space.

Conclusion

Picking out the correct generator is important. We need to know what sort of wattage our sump pump requires. Additionally, knowing what type of generator fits our needs the best is the best way to optimize our cash and space.

While most sump pumps of ⅓ hp power or more will do fine clearing our basement of flood water, we still need to make sure it’s properly supplied with electric energy. Our sump pump cannot perform well without it so it’s important. Don’t neglect the difference between surge power and running power, it’s an important detail for any interaction between a generator and sump pump.
