Stable water supply: Connect the water source to the washing machine using the water pipe to form a stable water flow channel, ensuring the washer receives sufficient water for the normal wash cycle. Precise water level control: Works with the washing machine's water level switch and inlet valve to accurately regulate the amount of water entering, so the water level reaches the appropriate height, improving washing results and preventing overflow. Auxiliary troubleshooting: When the washer has water leakage or other problems, closing the water inlet pipe helps determine whether the fault lies in the inlet system, enabling quick diagnosis and timely repairs. Pressure balance during inlet: During the water inlet process, the water inlet pipe balances the pressure in the line, preventing large pressure fluctuations from affecting the washer and ensuring stable operation of the inlet system. Compatibility and practical use: Designed for standard washing machines that use typical water level switches and inlet valves, providing reliable performance across common installations. Use scenarios: Installation or replacement: Connect the water source, verify a stable flow, and confirm the water level is correct for a normal cycle. Varying load sizes: Ensure proper water level to optimize washing performance for small to large loads. Fault diagnosis: Close the inlet pipe to isolate the inlet system and quickly identify leaks or inletrelated faults.
