Dual-lever-handle single-hole deck-mount kitchen sink faucets have two L-shaped handles that users pull toward or push away from themselves to start or stop the flow of water. Each handle is operated separately to control the hot and cold water supplies and adjust the water temperature. Single-hole deck-mount kitchen sink faucets combine the hot and cold water supplies to come out through a single spout, and they provide water for dishwashing, cooking, handwashing, and other tasks. They install into one hole on a flat surface, such as a sink or counter.
