"ROCO Real Estate purchased a 4” Smart Valve for a high-rise apartment building (Highland Towers) in Southfield, MI. The installation was easily completed by a local plumber with no prior SmartValve™ experience. Prior to installation, Highland Towers monthly water bill ranged from $8,000 to $13,000 over the previous 12 months. After installing the SmartValve™, our current water bills have been reduced by over 50%. Our recent water usage now ranges from $2,000 to $4,000 per month. We have ordered SmartValve™ valves for 5 additional properties and are in the process of installing them now."
