How It Works
The Problem Is In
Your Water Meter.
Your meter can't tell the difference between water and the air that enters the line. You're being billed for both. The Smart Valve fixes that β€” not through conservation, but through physics.
01

Air Enters Your Water Line

When water is demanded, pressure drops. As pressure drops, dissolved and entrained air expands β€” and your meter measures it as water. You pay for both.

02

The Smart Valve Maintains Back-Pressure

The patented device installs downstream of your meter and maintains pressure upstream slightly to maintain static pressure β€” so air cannot re-expand at the point of measurement (Boyle's Law). The meter reads only water.

03

Your Bill Drops From Day One

From the first billing cycle, you pay for a more accurate reading. No changes to water pressure, flow, or resident experience.

04

Backed by a 90-Day Guarantee*

If the savings aren't there, you get your money back β€” no questions asked. Plus a 10-year manufacturer warranty. Minimal risk, maximum upside.

*Customer is responsible for installation cost (1–3 hours by a certified plumber). The 90-day guarantee covers the cost of the Smart Valve device only.
