So you bought your dream faucet, and now you need to install it? Piece of cake. If you can turn off the water, you can install a single-handle pull-down kitchen faucet in mere minutes. Here’s how.
1. Turn off the sink’s water supply. If necessary, remove the old faucet.
2. Feed the flexible spray hose through the faucet’s spout—be sure you guide it in the right direction—and then through the hub.
3. Align the hole in the back of the spout with the clip on the hub, and work it on with a back-and-forth motion until it snaps into place.
4. Attach the sprayer to the end of the hose, and tighten the connection by hand. Delta MagnaTite Docking will keep the sprayer firmly in place while you work.
5. Depending on your countertop’s material and thickness, you may need an escutcheon and gasket to mount your faucet (get them here, if it's not included in the box).
6. Insert the faucet through the mounting hole in the countertop.
7. Under the sink, slide the U-shaped mounting bracket over the faucet shank; the supply lines should fit inside the bracket. Screw the nut onto the end of the shank, and use the Allen wrench to tighten the nut against the underside of the counter. Make sure the faucet is properly positioned over the sink before you tighten it for good.
8. Slide the hose weight over the hose, then push the hose’s end securely onto the faucet outlet. Place the clip over the connection to hold it in place.
9. Attach the water supply lines. Look at the ends of each line: A blue tip denotes the cold water line; red marks the hot water. Run each line to its corresponding water supply; the 3/8-inch compression fitting at the end should fit directly onto the water supply valve (if it doesn’t fit, you’ll need an adapter). If the lines are too long, wind them into a loop at least 8 inches in diameter, being careful not to create a kink in the lines. Screw the lines on by hand, then tighten snugly with the adjustable wrench; one wrench turn past finger-tight should be tight enough.
10. Open the faucet handle to “full on,” then turn on the water supply. Let the water run 30 to 40 seconds to remove any debris in the lines. Shut the faucet off and check for leaks. (If you notice any leaks, tighten the connections another half turn with the wrench.)
