T&S Brass Automatic Sensor Faucets limit the amount of daily water usage. Use a T&S electronic faucet and save money on water bills, gas bills, and other energy costs. The four ChekPoint Electronic Sensor Faucets can now be modified with an EC-Hydrogen kit, the newest addition to the T&S Brass ChekPoint™ product line. The hydro-generator generates and stores its own power with the flow of water, thus saving you energy and money. With it being a self-contained power source, you no longer need to rely on a transformer or a battery for power!
