• You want to add a backup pump for extra protection and replace your old AC pump before it fails 
• Your primary pump just quit on you and your basement took on a bit of water; a combo would allow you to add a backup pump to a new primary and easily double your protection 
• Your pit is small and wouldn’t allow you to install primary and backup pumps side by side 
• You’re not a plumber and are looking for an easy, DIY option

• Preassembled for easy installation
• Compact design fits into pits with diameters as small as 12 inches
• AC-powered primary pump operates as long as power is on
• Battery-powered backup pump will take over during a power outage

Yes, if/when water reaches the battery backup pump‘s Dual Float Switch, because:

• power is interrupted so the AC pump can’t run
• the AC pump fails
• the AC pump’s float has an issue and it doesn’t turn on the pump
• more water is coming into the sump pit than the primary pump can handle

This user-friendly controller:

• Sounds an alarm
• Illuminates a warning light
• Describes what to do for easy maintenance

• High-capacity Permanent Split Capacitor (PSC) motor 

• Durable, cast-iron construction 

• Upper and lower ball bearings for a smooth, energy-efficient, long life 

• A microreed Dual Float Switch is the most reliable way to activate a pump 

• 4 floats for added redundancy, with a Dual Float Switch on both the primary and backup pump in a combo system

• Protective cage for the primary pump prevents debris or wires from interfering with the float’s movement so it won’t get hung up
