Using your Bradley Verge Faucet is a breeze. Just wave your hand in front of the touch - free dual sensors, and the water will flow. The faucet comes with a battery pack of 4xAA alkaline batteries, which are easy to replace when the low - battery indicator light in the spout comes on. When it comes to water supply, connect it to the tempered line adapter for a tempered water flow. For maintenance, keep the faucet clean by wiping it regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the Brushed Stainless PVD finish. Remember, this item is non - returnable, so make sure it meets your needs before purchasing. Also, since it is certified lead - free, it is safe for your daily use.
