Auxiliary troubleshooting: When the washing machine has water leakage and other problems, closing the water inlet pipe can help determine whether the problem is in the water inlet system, which is convenient for users to quickly investigate the cause of the fault and carry out timely repairs. Maintain stable water pressure: Stable water flow can ensure that the water pressure in the washing machine is relatively constant, so that the washing machine can enter water normally under different water level settings to ensure the washing effect. Water source transmission core: Precisely connects the washing machine to the water source, stably delivers clean water, prevents water leakage, and provides continuous and safe water supply during the washing process. Connect the water source to the washing machine: Connect the water pipe to the washing machine to form a stable water flow channel to ensure that the washing machine can obtain sufficient water for the normal washing cycle.
