How can you get your spa with a venturi system to blow air?

To get your spa with a Venturi system to blow air, ensure that the air intake valves are open and free of blockages. Check the water level to ensure it's adequate for proper operation, as low water levels can disrupt the Venturi effect. Additionally, inspect the pump and filter for any clogs or issues, as these can affect airflow. Once everything is clear and functioning, turn on the spa pump to activate the Venturi system, which should draw air and create bubbles.
