Possible causes: 1) The sealing ring of the solenoid valve has aged or is damaged. 2) Pipeline joints are loose or improperly installed. 3) Product material lacks adequate pressure resistance (e.g., rupture caused by high water pressure).

Solutions: 1) Replace the sealing ring or solenoid valve (preferably use products made of copper or stainless steel). 2) Re-tighten the pipeline joints and ensure the installation meets specifications. 3) Choose products with higher pressure resistance ratings.

1) Regular maintenance: Clean the sensor, check the battery/power supply, and clean the filter. 2) Parameter calibration: Adjust the sensing distance and flushing time according to usage scenarios. 3) Model selection: Prefer DC-powered or self-powered products to reduce wiring issues. 4) After-sales support: Choose brands that provide a warranty of more than three years to ensure long-term stable use. 5) If problems persist, contact FAENZA for professional inspection and repair services.
