Abstract: A water flow valve positioned within a water distribution system just past a building's water meter. The valve compresses air bubbles into the water at the point where the water enters the meter, thus making the meter read less volume when the water passes through it. The air is compressed through back pressure created by the valve. With this increase in pressure, the air bubbles in the water begin to collapse and occupy less space. When the water, with collapsed air bubbles, passes through the meter, the meter reads basically only the water volume, as the amount of any air volume remaining is negligible. As such, the user's water bill is lower, as compared to if no valve had been disposed within the water line, and the bill reflect a more accurate reading of the actual amount of water that has been delivered.
