Tips on starting an overflow box

  • Make sure U-tube is installed properly in the overflow box.
  • Suck the air out of the U-tube using clear airline tubing (1 ft) until the U-tube is full of water. This is done by bending the airline tubing and inserting it into the U-tube.
  • Be sure the ends of the U-tube are fully submerged so that no air can enter. You may need to add more water to the overflow box as you do this.
  • The siphon is now primed and water will automatically move from the overflow box to the under-cabinet wet/dry filter.
