The SensiTap faucet saves water by using a special handle on a standard faucet body that turns on at low flow. Pull up on the handle a second time to activate full flow. The handle can be set at multiple flow rates as the user desires. You can save water by either restricting the flow through a fitting or by behavior modification, and the SensiTap does it by both methods. In this video with CONTRACTOR magazine, SensiTap Senior Vice President of Business Development Steven J. Gordon, PhD., explains how it works. www.SensiTap.com.
