1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect electrical power before touching solenoid valve coils or Aquastop connectors.
  • !Firmly shut off the domc water supply tap before unscrewing the inlet hose fitting.
  • !Check safety base drip tray for accumulated water triggering the anti-flood polystyrene float switch.
3. Preliminary Mechanical & Visual Checks
  • Remove and clean sediment and sand particles from the 3/4" inlet hose metal mesh filter.
  • Verify domestic dynamic water pressure is between 1.0 and 10.0 bar (0.1 to 1.0 MPa).
  • Inspect outer Aquastop hose jacket for expansion, pinch damage, or internal leak reservoir triggering.
