Tapmaster® hands-free faucet controllers do not rely on batteries or electricity to work. Instead Tapmaster® utilizes existing water pressure in the lines to provide short bursts of water as needed. Whether the environment is commercial or consumer based, replacing sensor faucets with a Tapmaster® will save you the cost spent on replacement batteries, electrical hook-up fees, and excess water usage—a massive cost-savings when calculated across the life span of your faucets. The result is a reliable and convenient method of turning water on and off that is easy to install and ecologically friendly to operate. We are changing the way the world uses the faucet.
