Why do AC sump pumps fail?

Eventually all primary sump pumps fail for 3 main reasons:

  • Power Outage: When the power goes out during a big storm, the AC pump can’t turn on and your basement will flood.
  • Primary Pump Failure: You likely won’t know your AC pump’s not functioning until it doesn’t activate during a storm and your basement floods.
  • Stuck Float Switch: Your AC pump’s float switch can get stuck and not turn on your pump, again leading to a flooded basement.

That’s why we recommend adding a Basement Watchdog battery backup pump to give you more protection and peace of mind.

  • When the power goes out, the backup system’s battery powers the pump, keeping your basement dry.
  • When your AC sump pump quits on you, your battery backup pump automatically activates, saving the day and your basement.
  • When your AC pump’s float switch sticks and fails to activate your primary pump, the float switch on your backup system turns the battery backup pump on.
  • In severe storms, when your primary pump can’t keep up with the inflow of water, the battery backup pump activates to assist the primary pump.
