The HydroGuard® Flushing and Impounding Protection system by Steinhardt offers dual functionality: powerful flushing of sewer channels and protection against backflow or impounding. It is powered solely by hydrostatic pressure and functions automatically—without requiring any external energy sources or moving parts.
