Not everyone is passionate about their water flow control valve, but Encompass group is. AccuValve™ is a patent-pending, proprietary design that is attached on the client side of the water meter. The AccuValve™ improves the accuracy of water usage measurement by providing a more stable, less turbulent flow of water through the meter. An accurate water usage measurement will give you more bang for your buck since you’ll only be paying for what you actually use. We liked the technology so much we bought shares in the company.
