Why Your Water Meter Bills You for Air — and How Smart Valve™ Stops It
City water arrives at your property mixed with air pockets from high-pressure distribution. Your meter can't tell water from air — it bills you for both. Smart Valve™ installs once on your main supply line, compresses that air before it's measured, and eliminates the charge permanently.

The narrated Smart Valve™ video covers every step — from city grid air entrainment to verified meter reduction.
Why Commercial Water Meters Overcharge
Three things happen between the city main and your bill — and every step adds air you're paying for.
High-Pressure City Grid
Municipal water is pumped through distribution mains at 200+ PSI. Cavitation, hydrant work, and main breaks fold air pockets directly into the flow. By the time water reaches your service connection, it carries entrained air invisible to the eye.
Pressure Drop → Air Expands
Your service line is smaller than the main — pressure drops sharply at the connection. Those compressed air pockets expand to 3–4× their original volume inside your pipe, immediately before the meter. The meter never knew they were there.
Meter Bills You for Air
Water meters measure volume. They cannot distinguish H₂O molecules from air. Every expanded air pocket registers as billable flow — and in most municipalities, the same inflated reading drives both the water charge AND the sewer charge.
How Smart Valve™ Fixes It — Once, Permanently
Installs After the Meter, Once
A licensed plumber installs Smart Valve™ directly on your main supply line — client-side of the water meter — in a single 3.5-hour water shutdown. No electricity. No moving parts. No follow-up service.
Holds Controlled Back Pressure
Smart Valve™ creates a calibrated resistance in the supply line. This back pressure compresses the entrained air pockets back to their true volume before water crosses the meter billing point.
Meter Records Less — You Pay Less
With air compressed to its actual size, the meter records only the true volume of water flowing through. Your bill drops. Sewer charges — calculated from the same meter — also drop. The savings are permanent.
Zero Impact Downstream
The back pressure Smart Valve™ creates does not reduce pressure at your taps. Every resident, guest, tenant, or patient receives identical water service. The only thing that changes is what the meter records.

Smart Valve™ Works on Any Master-Metered Property
Any commercial or multi-residential property on a municipal water meter qualifies. Air entrainment is a universal problem — the meter doesn't know what industry you're in.

What problems does the Smart Valve™ solve beyond just saving water?
The Smart Valve™ addresses five distinct problems that commercial property owners and facility managers face every day.
You're being billed for air, not just water.
Water meters measure volume — they cannot distinguish between water and air. When pressure fluctuates in your building's plumbing (which happens constantly), air bubbles form and travel through the system. Every cubic inch of that air registers on your meter at the same rate as water. The Smart Valve™ maintains constant back pressure upstream of the meter, preventing air from expanding and being measured as billable volume.
Pressure surges are damaging your plumbing and equipment.
Commercial water pressure should run between 40–80 PSI. Municipal supply pressure is often much higher and fluctuates significantly throughout the day. These surges cause the meter to over-spin, damage seals and gaskets, accelerate pipe wear, and increase leak frequency. The Smart Valve™ acts as a shock absorber — its proprietary variable spring-loaded technology smooths out pressure peaks and valleys before they reach your fixtures.
High pressure causes fixtures to use more water than designed.
Water fixtures in commercial buildings are designed for approximately 60–65 PSI. When supply pressure exceeds this, fixtures push more water through than intended — every flush, every faucet, every shower. The Smart Valve™ precisely controls downstream pressure, reducing this overconsumption in all non-volumetric uses.
Water hammer is damaging your pipes.
Water hammer — the loud banging sound when water flow is suddenly stopped — is caused by pressure surges in the system. It stresses pipe joints, damages valves, and can cause catastrophic pipe failure over time. Commercial plumbing failures cost U.S. businesses more than $3 billion annually. The Smart Valve™ eliminates the pressure spikes that cause water hammer.
Undetected leaks are costing you thousands.
High pressure accelerates leaks at seals and gaskets designed for 65 PSI. Buildings that don't manage pressure lose an average of 10,000 gallons per year to undetected leaks. By reducing downstream pressure to the designed operating range, the Smart Valve™ reduces the leak rate at every seal and gasket in the building.
How does the Smart Valve™ actually reduce a water bill?
Three physical principles — established physics applied to commercial water metering.
Air Compression
By maintaining near-city static pressure upstream past the water meter, the valve prevents air volume from expanding due to the pressure drop created by water demand. Air passes through the meter in its compressed state — taking up less volume — and only expands back to its original size after passing through the valve. Result: your meter records less volume.
Flow Stabilization
Water meters are accurate only within a specific flow range (GPM). Surges from municipal supply variability or switching between static and dynamic flow push the meter outside this range, causing it to over-read. The Smart Valve™'s adjustable technology eliminates these peaks and valleys, keeping flow in the accurate metering range.
Pressure Reduction
A controlled pressure drop downstream reduces actual water consumption in non-volumetric uses — showers, sinks, hoses, and similar fixtures use less water per minute when operating at 60–65 PSI versus 80–100+ PSI.
Questions About How Smart Valve™ Works
More questions answered on our full FAQ page →
How does Smart Valve™ reduce commercial water bills?
Smart Valve™ installs once on the main water supply line, directly after the water meter. City water is delivered under high pressure (200+ PSI), and this pressure causes cavitation, hydrant work, and main repairs to fold air pockets into the flow. When water enters a smaller service line, pressure drops and those air pockets expand to 3–4x their size. Water meters count volume — they cannot distinguish air from water, so every bubble is billed. Smart Valve™ holds controlled back pressure that compresses the air to its true volume before it crosses the billing point, so customers are charged only for actual water delivered.
Does Smart Valve™ affect water pressure at the taps?
No. Smart Valve™ steadies flow and compresses entrained air without changing the pressure experienced at any tap, fixture, or equipment in the building. Every occupant receives identical water service. The only change is what the meter records.
What is the minimum guaranteed savings with Smart Valve™?
Smart Valve™ comes with a written performance guarantee of minimum 15% reduction on every installation. If the verified savings fall below 15%, you do not pay. Typical results range from 15%–35% annually, with some properties exceeding 40% in peak months.
Does Smart Valve™ require electricity or ongoing maintenance?
No. Smart Valve™ operates entirely on water pressure — no electricity, no moving parts that wear out, no consumables, and no recurring service. Installation requires a single water shutdown of up to 3.5 hours. After that, there is nothing to maintain.
How is Smart Valve™ different from a standard pressure-reducing valve?
A pressure-reducing valve (PRV) lowers the downstream pressure experienced by the building. Smart Valve™ does not reduce downstream pressure — residents and tenants experience no change. Instead, it compresses entrained air pockets in the supply line before they are measured by the meter, eliminating billing for air that was mixed into the municipal water supply before it reached the property.
Is Smart Valve™ certified safe for drinking water systems?
Yes. Smart Valve™ holds NSF/ANSI/CAN 61 certification (drinking water system components) and NSF/ANSI 372 certification (lead-free compliance). These are the same standards required for all components in commercial and residential potable water systems across the United States and Canada.
Is the Smart Valve™ the same as a pressure regulator?
No. A standard pressure regulator only reduces downstream pressure and requires regular maintenance. The Smart Valve™ does five things simultaneously: eliminates air volume measurement, regulates pressure surges, reduces downstream pressure, prevents backflow, and stabilizes flow rate. It requires zero maintenance and has a 20-year lifespan.
Will the Smart Valve™ reduce my water pressure noticeably?
The valve is calibrated to your specific building's system. It reduces pressure to the optimal operating range (approximately 60–65 PSI) for your fixtures. Most buildings experience no noticeable difference in water pressure at the tap — only a reduction in the overconsumption caused by excessive pressure.
Can the Smart Valve™ prevent water hammer?
Yes. Water hammer is caused by pressure surges when flow is suddenly stopped. The Smart Valve™ acts as a shock absorber against pressure surges and drops, eliminating the conditions that cause water hammer and protecting your plumbing infrastructure.
Does the Smart Valve™ work with my existing water meter?
The Smart Valve™ is compatible with over 99% of all water meters currently in use in the United States, including both older mechanical meters and modern digital units.
How long does installation take?
Installation typically takes 2–4 hours and requires only a brief water shutoff. There is no construction, no pipe replacement, and no disruption to building operations beyond the installation window.
