Kitchen faucets need to be selected based on the number of holes in the kitchen sink, whether it is a drop-in sink, countertop, or undermount sink. The faucets shown on the next page have many wonderful features and are grouped together by the pattern of faucet drillings in the sink/countertop. The key below will help identify those features that are ADA accessible, WaterSense Certified, use Diamond Seal construction technology or turn on and off by just touching the spout.
Kitchen sinks typically come standard with a hole pattern that matches
the size of the fixture. Start by selecting the type of sink that you
are looking to purchase a faucet for.
Touch20 Technology 
The cutting-edge pull-down spray head features three relevant technologies from Delta that help simplify using water in the kitchen while providing a revolutionary leak-free, lead-free water delivery system. With Touch
20 Technology users can start and stop the flow of water with a simple tap anywhere on the spout or the handle, saving both water and energy.
Magna Tite ™ 
A magnetic closure called MagnaTite™ intuitively returns the pull out spray head to its original docked position, helping to keep both the faucet and kitchen looking neat and orderly.
ADA 
Some people need fixtures that are compliant with the Americans with Disabilities Act.
WaterSense 
labeled faucets and faucet accessories (such as aerators) are
high-performing, water-efficient fixtures that have been evaluated by the Environmental Protective Agency and determined that they function better or equal to faucets using the older flow rate. If every household in America installed a WaterSense labeled faucet or aerator, we could save more than 60 billion gallons of water annually. A WaterSense-labeled kitchen sink faucet or aerator will help you reduce water use in your home and save money on water bills without compromising function.
DIAMOND™ Seal Technology 
It is Delta's revolutionary new water delivery system. An internal contact surface made up of tiny diamonds makes the valve leak-free and extraordinarily durable. It also keeps water free of contact with potential metal contaminants.
