Stable water supply for reliable washing: Connects the water source to the washing machine to form a stable water flow channel, ensuring the machine receives sufficient water for the normal wash cycle. Precise water level control: Works with the washer's water level switch and inlet valve to accurately regulate the amount of water entering the machine, so the water level is correct, the washing result is consistent, and the risk of overflow is reduced. Quick fault isolation for waterrelated issues: If a leak or other problem occurs, closing the water inlet pipe helps determine whether the fault lies in the water inlet system, enabling faster diagnosis and timely . Pressure balancing for stable operation: During the water inlet process, the pipe helps balance pressure in the line to prevent large pressure fluctuations from affecting the washer, supporting smooth and reliable inlet performance. Compatibility and performance: Designed to work with standard washing machine water inlet configurations, providing dependable performance with typical inlet valves and level switches. Use scenarios: installation or replacement: Ensures a stable and adequate water supply for a proper wash from the start. Areas with variable water pressure: Helps maintain consistent water filling and washing performance despite pressure changes. Inlet system troubleshooting: Use the inlet shutoff to quickly verify whether a leak or fault is related to the inlet pathway, speeding up .
