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.
