A system and method for determining the discharge pressure of a gas handler in a well. The system includes an electrical submersible pump connected to a discharge head disposed in the well, a gas handler discharge line configured to connect the discharge head to a sensor, a processor configured to receive data from the sensor and determine the discharge pressure of the gas handler based on the received data, and a display configured to display the discharge pressure of the gas handler. The method includes attaching a discharge head to the gas handler, attaching a gas handler discharge line from the discharge head to a sensor, measuring pressure transferred from the gas handler into the electrical submersible pump, receiving the measurement of the pressure transferred, determining the discharge pressure of the gas handler based on the measurement of the pressure transferred, and displaying the discharge pressure of the gas handler.
