Integrating with the pre-filter, it forms a comprehensive leak-proof safety net for the entire house. Through water pressure and flow monitoring, as well as multi-point water accumulation probes, it achieves automatic valve closure and APP alarming in milliseconds in case of pipe bursting and concealed leaks. The pre-filter intercepts impurities, effectively protecting sensors and solenoid valves and reducing false alarms and malfunctions. The system supports intelligent self-checking reminders for filter blockage, seal aging, etc., facilitating remote operation and maintenance. With multi-probe coverage across multiple layers and zones, it is particularly suitable for large-sized homes with complex piping systems.
