Does the thought of a power cut and the pump failing during a heavy rainstorm leave you in a restless state? Well, that’s the sign for you to invest in a battery backup sump pump.

In this article, we will talk about the functioning of these pumps, their cost, and whether or not they’re worth investing in. So if that’s something you’re interested in, consider reading the article till the end.

How does a battery backup sump pump work? 

Usually, the traditional sump pump is installed in a sump basin located in the basement of your house. Whenever there’s a rise in the water level, the sump pump gets activated by a trigger from the floating switch or pressure sensor. But as it runs on AC power, it goes dead when there’s a power cut. 

This is where a battery backup sump pump comes into play. When your primary sump pump fails, the backup one gets activated and starts running on DC power (Battery). The pump is usually placed higher than your primary pump. It gets activated by the rising of the float or tether valve with the increase in water levels. 

If the primary pump gets too flooded with water while working, the backup pump starts running to provide additional support. However, one must keep in mind that the pump can only work for a limited period. For that, you must check the number of gallons it can pump per battery life.

Do you need a battery backup pump? 

Well, as long as you’re living in a world where the power supply is unlimited and there isn’t any threat of power outage, we would say you don’t need one. But unfortunately, that’s not the case in the present world.

We face power outages more often than we would like. At such times, the backup sump pump draws power from the battery. During rainstorms, this feature of the pump enables it to keep the house dry and clean.

How much do you need to spend on a battery backup sump pump? 

Usually, the cheapest models cost around $150. But with the increase in features, the cost of a battery backup sump pump increases to the upper range of $300. You can still find moderately expensive models in the range of $200-$300.

But before you go ahead and buy the cheapest model available in the market, we recommend you do some research. It’s good to check out the reviews of battery backup sump pump before investing in the model of your choice. Compare the features of the model with the expensive ones, and then decide what’s worth investing in. 

Usually, people go for the pumps that are a bit on the pricier side because they’re more reliable in terms of performance.


Now that you know how important a battery backup sump pump is, it’s time for you to buy one before it’s too late. After all, no one wants to spend thousands of dollars repairing the water damage caused by their own carelessness.
