Basement Sentry Water Driven Backup Sump Pump
This pump protects your basement even when the power goes out. It works with city water pressure instead of electricity or batteries. When water rises above the normal high water level in your sump pit for any reason, the float on the backup pump rises. The rising float opens a valve that routes city water through backup pump. This flow of city water creates a powerful vacuum, which pulls water out of your sump pit and pumps it outdoors. It will remove up to 2 gallons for every gallon of city water used. When the water level drops, the backup pump float shuts off the valve and the flow of city water stops. This pump can install in a sump basin or out of sight in the rafters. It can be installed with a submersible or pedestal pump. It must be used in homes with city water and you need a sump basin at least 18-in.  wide x 22-in. deep.

Sump pumps are highly dependable, but basement sentry systems can give you even more peace of mind when you need to keep your basement dry and free of flooding. 

At Star Water Systems, we're your one-stop shop for basement water systems you can trust. We specialize in providing our customers with high-performing devices to serve all of their residential water movement needs.

Basement sentry pump systems, also known as sentry backup sump pumps, are designed to take over water removal operations when the primary pump fails. Sump pumps can fail under many circumstances, including:

  • Power outages.
  • Wiring or electrical issues.
  • Pump damage.
  • Mechanical malfunctions.
  • Pit obstructions.
  • Pump overload.

In these situations, it's essential to have a reliable basement sentry battery to ensure that water levels remain managed, pumping excess water away from your home while protecting it from flooding and water damage.
