After installation, hand-tighten the connector first, then use a wrench to reinforce it by an additional half turn, avoiding excessive force that could crack plastic components. For wall-mounted or built-in models, it is recommended to add a waterproof silicone sleeve at the connection point and perform a 30-minute water test to confirm there is no leakage before regular use.
If the setup involves a multi-valve water distribution structure, check the sealing condition of all branch interfaces simultaneously to prevent localized leakage caused by uneven water pressure.
