Intelligent Water Management, Inc. calls BrainPipes “mind control for plumbing.” The system relies on a check-valve installed in the main water supply, which remains in the “off” position until there is a call for water. Unlike typical leak detection systems, sensors placed at each faucet and fixture detect losses in water pressure. If this occurs without a “legitimate request” for water, such as a toilet flushing, the sensor sends an alert. Monthly usage reports also help homeowners monitor and change their habits.
