A freezing prevention apparatus for a water gauge and a water pipe is provided to prevent freezing of a water gauge and a water pipe by injecting air into the pipe and by pushing water in the water gauge and the water pipe. A freezing prevention apparatus for a water gauge and a water pipe comprises a motor/air pump(1), a suction hole(2), an exhaust hole(3), a valve support pad(4) attached to a fan-shape gear, a water valve(5) and a U-shape bolt(6). The motor/air pump sucks air from the suction hole and exhausts the air to the exhaust hole while being rotated by switch on/off operation of a user. In this time, the user opens the water valve, water remaining in the water gauge and the water pipe is pushed out through the water valve and only air remains in the water pipe. |
