The Adjustable Flow Management Valve
Executive Summary
The office building valve installation reduced average monthly gallons used by 38% and the average utility bill by 33% over a sample set of 6 months in a YOY comparison. Payback is about one year.
The valve is modulating the speed of the pressure drop as the clay valve opens and drops the water into an open tank. The meter’s cavitation much less with the Smart Water Valve and the reduction in operating expenses is greater than we anticipated.

Testimonial
“In 2018 we installed a 6” Smart Water Valve on the supply to our House Tank for potable water at 11811 North Frwy, a 9 Story multi-tenant office building in North Houston. Our monthly water bills decreased by 30% over the same months of the prior year. Based on our results, we intend to begin adding Smart Water Valves throughout our portfolio.”
