Battery Backup Sump Pump Basics

How To Install A Battery Backup Sump Pump

Rainy weather is enough of a downer on its own, but add in a flooded basement and it’s more than that. This is why homeowners should know how to install a battery backup sump pump to keep their properties dry even when a storm causes an interruption in power. Installing a backup sump pump powered by batteries means you can avoid the cost and cleanup that result from water backing up into your home.

How Does a Battery Backup Sump Pump Work?

Ordinarily, your sump pump is connected to the power in your home, meaning it won’t function if there’s an outage. A battery backup system means your unit will kick on and start pumping water out of your basement even if the electricity to your house is interrupted.

How to Install a Sump Pump Battery Backup

There are kits available to add battery backup to an existing sump pump. Although the exact installation process will vary depending on the model you choose, installing it will most likely involve a few important steps:

  1. Mount the battery and control unit to the wall: This allows for easier access and keeps the unit out of the sump pit, where it may be damaged by water.
  2. Connect it to the sump pump: Most backup units feature an AC pass-through, which means you can plug the pump into them and then plug them into your outlet.
  3. Test the backup: Once everything is connected, activate the pump to make sure it works normally when it has power. Then, unplug the backup unit to simulate a power outage.

Installing a Battery Backup Sump Pump From Scratch

If you don’t already have a sump pump, installing one that comes with a battery backup is a great choice. Here are the basic steps involved:

  1. Apply Teflon tape to the threads of the check valve, then screw it onto the new pump.
  2. After applying Teflon tape to the threads of the battery-powered pump, attach it to the check valve and set both pumps into the sump pit.
  3. Cut PVC pipe to form discharge pipe, then secure it to the existing discharge pipe.
  4. Connect battery to backup pump and plug the main pump into the outlet.

The Importance of Regular Maintenance

Caring for your sump pump and backup pump is important if you want them to function when you need them. Here are some tips:

  • Remove your pumps from the pit each year to check for rust.
  • Keep the unit lubricated according to manufacturer’s specifications.
  • Check discharge pipe for blockages.
  • Know how to reset your sump pump backup battery by reading the owner’s manual.
