While spring showers bring May flowers, the change in the weather may also bring severe storms. A reliable sump pump with a battery backup system can protect against unforeseen damages. You’ve made a major financial commitment to your home and need to protect that investment against flooding and water damage in your basement. 

Many homes with basements or crawl spaces are protected from ground water damage by a network of drainage tubes around the foundation. The drainage system directs water into a shallow pit or sump, allowing the sump pump to push the water out and away from the home through a discharge pipe. 

Sump pumps work automatically each time water fills the sump, but a damaged or broken pump can quickly allow water to overflow the sump, potentially resulting in unanticipated basement flooding.  

Sump pump battery backup systems are supplementary to primary pumps and when a primary pump fails due to a power outage, mechanical failure or any other reason, rising water levels will automatically trigger the battery backup system.  

When a high-quality battery backup system is installed, thousands of gallons of water can be pumped out on a single charge—some systems can pump out enough water to fill a small swimming pool! Although typically a battery backup pump system includes a primary pump and a battery backup pump, consider a three-pump system for ultimate protection. In this configuration, the primary pump would do most of the heavy lifting, with a secondary pump automatically starting when water rises to the appropriate level. The battery backup acts as a failsafe in the event of a power outage or mechanical failure. 

Some sump systems include a battery that converts DC power into AC power to charge the primary pump, but transforming DC power to AC is a highly inefficient process, and these battery backup systems often lose their charge within an hour's time. Foundation Systems of Michigan recommends using DC battery power, since DC current can run continuously for up to 10 hours and intermittently for several days allowing several hours of additional protection from water damage. Once power is restored, the battery will automatically recharge for the next emergency. 

The decision over which backup sump pump system to use in your home is driven by your specific plumbing system setup, your water volume needs, and other factors. Water powered backup sump pumps may not provide the efficiency and reliability of a battery powered backup system since they generally have a lower pumping capacity—heavy rains and water volumes will quickly overwhelm these systems. Water powered sumps also cost considerably higher to run for a long time compared to a battery-operated sump. In addition, a home with a water well will not support a water-powered back up system.

Investing in a sump pump with a battery back-up system will provide peace of mind, 24 hours a day, whether you’re home or away. Call the experts at Foundation Systems of Michigan today to discuss your Michigan sump pump needs.
