Independent dual-control outlet: independent water outlet with dual control. Rotate left or right to drain water, with a separate switch to operate the outlet; controls function independently. Universal installation: requires only 5.5 cm projection from the wall during installation. The faucet on a Neral washing machine typically projects 10 cm from the wall, which does not affect installation or use. Durable construction: the main body and coil are made of thickened brass, delivering explosion-proof, pressure-resistant, and durable performance. Drill-free mounting: no drilling required; the mounting bracket rotates 360-degree, and the union nut is easy to install, saving space. Use scenarios: - Bathroom retrofit where independent drainage control is needed for a toilet accessory or bidet. - Compact bathrooms with limited wall depth, where a shallow 5.5 cm projection improves fit. - Laundry or utility areas with a Neral washing machine faucet that projects 10 cm from the wall; installation remains compatible and unobtrusive.
