Knowing the answer to these questions can help you to determine if your home needs a sump pump battery backup system:

  • Do heavy rains or snow melt because extra water to infiltrate the basement?

  • Are powers disruptions frequent during certain times of the year due to seasonal weather conditions?

If you answered yes to any of the above questions, then you need a sump pump battery backup.

Importance of Battery Backup Sump Pump Systems

Your home is an expensive investment. That’s why preventing water damages from occurring by installing a sump pump battery backup system can save you time, money and can help to extend the lifespan of your home. Here are just a few of the many benefits that a battery backup system for your sump pump will provide you:

  • No moving parts to wear out
  • Highest gallon per hour pump capacity
  • Charging system allows for simultaneous charging and pump operation
  • A secondary system prevents water damages during heavy water infiltration seasons
  • Plug and play capabilities ‚Äď install it and forget it
  • Automatic sensors detect water intrusion and instantly pump away water ‚Äď even if you‚Äôre not home
  • Warning alarms alert you to when the battery needs maintenance

Battery Backup Vs. Generators

Generator can serve as a backup for your sump pump as well as your home. But with many sump pump systems, the generator needs to have enough wattage and amperes to provide the sump pump backup power, as it needs to maintain the sump pits water level. A battery backup sump pump will pump away water easily as it uses a secondary sump pump system that is designed for DC power to pump water from the sump pit, eliminating the need to use the primary pump right away. A battery powered secondary sump pump compared to a generator powered backup system for your primary sump pump can pump away just as much water as the primary pump, with the exception that you can’t recharge the battery until the power is restored. Typical battery for sump pumps will have a run time of around 5-8 hours, while a fuel powered generator can be refilled as often as necessary to maintain the water level in the sump pit.

Battery Backup Sump Pumps Vs. Water Powered Sump Pumps

A water powered sump pump works on water pressure from a municipal water line to create a vacuum that rotates a turbine to pump out the water from the sump pit. Water powered sump pumps can only be used when water pressure exceeds 40 psi. If you own your own well, then a battery backup sump pump is required to maintain the sump pits water level. Water powered backup sump pump systems cannot be used in conjunction with an electrical powered primary sump pump for obvious electrical safety reasons.
