Basepump® CB1500
Commercial Water Powered Backup Sump Pump

  • Basepump CB1500 commercial grade backup sump pump is designed for use in commercial buildings and some larger homes with sufficient water supply to operate the pump.
  • Don't dismiss installing a backup sump pump because you have a generator. Pumps fail all the time.
  • A battery backup may not be able to keep it dry long enough for the sump pump to come back online.

This is designed for use in:

Hotels ~ Restaurants ~ Apartment Buildings ~ Condominium High-Rises ~ Factories ~ Office Buildings ~ Large Homes ~ Churches

Five year limited warranty seal.
  • The Basepump CB1500 is the most powerful water powered backup sump pump on the market today.
  • Most larger buildings, complexes, and upscale homes have larger water supply piping and are capable of running this larger pump.
  • The larger building also tends to have larger basement areas and therefore more potential water in the sump.
  • The CB1500 is capable of pumping 1,500 to 2,000 Gallons per Hour (GPH), on average, from the sump. (This depends on the water supply to the pump as well as the piping length and condition, and height to which it must pump.)

Sump Level Alarm (SLA) to detect and warn of high sump water levels.

Test button and silencer button make this easy to maintain and control. It can also be connected to your building security system for added protection.

Optional Backflow Prevention Devices for the CB1500:

1. Atmospheric Vacuum Breaker (AVB) for the CB1500

CB1500 AVB faded to emphasize the AVB unit.
AVB Valve for Backflow Prevention
  • This widely accepted backflow prevention valve is installed on the non-pressure side of the main control valve.
  • It includes the correct riser piping in order to meet code regulations.
  • This valve admits air into the system whenever the water flow stops to make it impossible to back-siphon water from the sump into the potable water pipes.
  • When using this valve, the discharge from the CB1500 must exit the building separately from the primary sump pump and self-drain to the outdoors.

2. Dual Check Valve (DCV) for the CB1500

  • This backflow prevention device is installed on the pressure side of the municipal cold water pipe that is connected to the Basepump.
  • The dual check valve gives the installer more flexibility than the AVB valve because the pump may be mounted in more configurations.
