There is only one Biblical mode for water baptism, and that is by immersion. The Bible gives no other method, be it sprinkling or pouring. Please note:
Matthew 3:16 “As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and lighting on him."
Acts 8:38 “And he gave orders to stop the chariot. Then both Philip and the eunuch went down into the water and Philip baptized him."
