The invention discloses a water tank pressurization system for an airplane. Comprising a water tank, a pressure switch, an air header pipe assembly, an air compression pump and a controller. The upper part of the water tank is provided with a pressure switch and an air inlet, the air inlet is connected with the air header pipe assembly, and the pressure switch is electrically connected with the controller; the air header pipe assembly comprises a reciprocating valve, two inlet ends of the reciprocating valve are connected with an engine air entraining system and an air compression pump respectively, and an outlet end of the reciprocating valve is connected with an air inlet of the water tank. And the air compression pump is electrically connected with the controller. According to the invention, the gas pressure in the water tank on the airplane can be monitored, and the pressure stability of pressurized gas in the water tank is ensured.
