The HydroGuard® Inverted Siphon Flush by Steinhardt is a specially designed flushing system for maintaining the hygiene and efficiency of inverted siphons in wastewater networks. It uses stored water to create a powerful, controlled flush that removes sedimentation, biofilm, and blockages without the need for external energy sources or moving parts. The system helps prevent clogging, odours, and operational disruptions in sewer infrastructures.
