Using this touchless faucet is a breeze. Just wave your hand in front of the sensors, and the water will turn on. It's powered by a battery pack with 4xAA alkaline batteries, so you don't have to worry about a complicated installation. Keep an eye on the indicator lights on the spout. They'll tell you if the faucet is powered, when it's activated, and when the batteries are running low. When it's time to change the batteries, simply open the battery compartment and replace them. To keep your faucet looking its best, clean it regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners, as they can damage the Brushed Bronze PVD finish. This faucet is certified lead-free, so you can use it with confidence, knowing it's safe for you and your family. Also, since it's a non-returnable item, make sure it's the right fit for your needs before purchasing.
