2. The water pump rotates and sprays water, but the fog is small and the pressure decreases. Turn on the water pump and check whether there are sundries in the pump chamber. Whether the motor bracket is loose, tighten the screws. Note that the inlet and outlet valves cannot be installed in reverse.
3. After the pump is used for half a year or one year, the pressure drop and spray quantity are small. Turn on the water pump and tighten the motor bracket screws. Change the direction of the small die in the cavity up and down, or change the small grinding plate.
