Do You Need a Backup Sump Pump? Here’s All You Need to Know

There’s nothing worse than finding out you need a backup sump pump after a catastrophic incident. However, not every homeowner knows what a backup sump pump is, the benefits of having one, and what types of houses should install one. 

That’s why we’ve compiled this beginner’s guide to backup sump pumps. Here, we’ll cover everything you need to know and answer the question, “Do I need a backup sump pump?” with a list of factors to consider. 

So, keep reading for the complete guide to backup sump pumps. 

Sump Pumps 101: The Basics 

First and foremost, let’s define a sump pump before discussing backup sump pumps. A sump pump is a device designed to remove accumulated water from a sump basin, typically found in home basements. Its primary function is to prevent basement flooding and keep the area beneath a building dry.

Here’s how they work: 

1. A pit, known as a sump basin, is constructed at the lowest point of the basement or crawl space. This basin collects water that seeps in from the ground or from rain.
2. When the water in the sump basin reaches a certain level, a float switch or pressure sensor activates the sump pump.
3. The sump pump then pumps the water out of the basin and away from the house, usually to a drainage area or a dry well.

On average, sump pumps last 7-10 years when maintained properly. That includes annual inspections intended to address metal parts and small components. Because they come in contact with water, they eventually develop rust or can come loose and fail at the worst times. 

Of course, that’s just the primary sump pump. These can often fail for a variety of reasons and allow water to seep into areas it shouldn’t. Hence, the rise of installing backup sump pumps. We’ll learn about those next. 

Who Needs a Backup Sump Pump? 

Let’s put it this way – the #1 reason basements flood is failing sump pumps. This is a good enough reason for many homeowners to install a secondary or backup sump pump. A backup sump pump is an auxiliary pump designed to take over the function of the primary sump pump in the event of its failure or if it cannot handle the volume of water.

Put simply, a backup sump pump is beneficial for anyone who relies on a sump pump to keep their basement or crawl space dry. But particularly in the following situations:

1. Areas Prone to Heavy Rainfall or Flooding: Homes in regions with frequent heavy rains or a high risk of flooding should have a backup sump pump to handle excess water when the primary pump is overwhelmed.
2. Frequent Power Outages: A battery-operated or water-powered backup sump pump is crucial for homes in areas with frequent power outages. It ensures that water can still be removed when the main pump loses power.
3. Finished Basements: Homes with finished basements or valuable items stored in the basement should have a backup pump to protect against water damage.
4. High Water Tables: Properties in areas with high water tables are more susceptible to water infiltration and would benefit from a backup system to manage continuous water flow.
5. Critical Sump Pump Usage: If a sump pump is essential to prevent frequent flooding, having a backup is a good preventive measure to avoid basement flooding and water damage.

Types of Backup Sump Pumps 

Next, it’s time to learn about the two most common types of backup sump pumps: battery-operated and water-powered. However, remember that a plumbing professional should suggest the type you install based on your home’s unique characteristics. Here are the main differences between each to help you decide which you prefer.

Battery-Operated Backup Sump Pump

Battery-powered backup sump pumps use a rechargeable battery to power the pump. They automatically activate when the primary pump fails or during a power outage. One big question every homeowner always asks is, how long can a battery-powered backup sump pump last? Typically, the battery will operate for several hours, depending on its capacity and load. 

One major difference between battery-operated and water-powered backup sump pumps is that battery-powered models need to be inspected and maintained more frequently to ensure the battery is charged and in good condition.

Water-Powered Backup Sump Pump

Water-powered backup sump pumps use the pressure from the home’s municipal water supply to pump water from the sump basin. They’re also automatically activated when the primary pump fails and can run indefinitely as long as there is adequate water pressure.

They’re a popular choice due to the fact that they operate independently of the electrical system, making them ideal during power outages.

Regardless of the type, many backup systems come with alarms to alert homeowners when the backup pump is activated or if there is a problem. Some systems even combine a primary and backup pump in one unit, offering a more integrated solution. 

Again, this guide is the first step to considering whether you need a backup sump pump or not, but always consult a professional to make the final decision and selection.
