HOW THE IN-WALL PRESSURE ASSIST TANK WORKS
3 Stages of the Flush Cycle
Flush Stage:
The flush begins when the actuator valve is depressed, and ends when the tank has discharged all of its water
through the bowl.
Air Intake/Bowl Refill Stage:
As water rushes through the empty tank past the fill tube to refill the bowl,it causes a Venturi
effect, which draws air into the tank. The small amount of water in the air inducer cap disappears, and a suction sound occurs
for 10-12 seconds.
Pressurization Stage:
After the flush valve seats the tank begins to fill with water. The ball in the air inducer floats against the
seat in the cap and air intake stops. A small amount of water fills the cap. Water continues to fill the tank, compressing the a
ir
inside, until the force of the regulator spring is overcome and the supply is shut off.
