A Smarter Solution
for Lower Water Bills

Your water meter doesn’t just measure water—it also measures air, making your bills higher than they should be.

Our patented valve removes air, reducing water meter readings and cutting costs by up to 30%.


  • Air

    Removes Air That Inflates
    Your Water Bill

    Most water meters can’t distinguish air from water — so when air enters your plumbing, you get charged for it. The NOI Valve extracts air from the line before it reaches the meter, eliminating false volume readings and helping you pay only for actual water used.

  • Efficiency

    Stabilizes Flow
    for Accurate Metering

    By creating controlled back pressure, the NOI Valve compresses any remaining air on the utility side of the meter and smooths out turbulent flow. This results in steady, laminar movement through the meter — reducing vibration, pressure fluctuations, and over-registration.

  • Installation

    Engineered to Control Velocity
    Without Sacrificing Pressure

    The valve briefly constricts the pipe by 5% (similar to the Venturi effect), running water through a calibrated 3mm restriction before opening back up. This precision design reduces erratic velocity changes that can trigger inflated readings — all while maintaining normal water pressure and flow.

Simple Installation.
