The standard international 4-pipe water outlet is made of refined brass material, which can be directly connected to household conventional water pipe connectors/faucet metal hoses/shower hoses/shower hoses. The touch button has a longer service life, electronic control, good sealing, not afraid of humid and watery environments, and avoids mechanical failures such as water ingress, oxidation, and corrosion, which cause the buttons to be unable to adjust. The water inlet/outlet is made of brass, which is strong and corrosion-resistant, and is not easy to be damaged in various environments; it has high stability, high-temperature resistance, and no rust. Does not pollute domestic water.
