- 1). Turn the water off to your sink before you install your spray nozzle. Two shutoff valves are underneath your sink. One is for your hot water, and one is for your cold water. Turn both valves clockwise to shut off the water. Turn your water handles on to release pressure in the water lines.
- 2). Place the threaded end of the grommet, or decorative ring, into the hole on the right side of your faucet. If you do not already have a hole in your sink, there should be a tab you can knock out with a hammer and screwdriver. Place your screwdriver in the center of the knockout and hit your screwdriver handle with your hammer.
- 3). Place the retaining nut on the threads of the grommet, and turn the nut counterclockwise, by hand, to tighten it. Complete this step from underneath your sink.
- 4). Drop the water line on the end of your spray nozzle through the hole in the grommet. Your spray nozzle should be setting in the grommet, and your water line should be underneath your sink.
- 5). Remove the water line cap off of your spray nozzle connection, using an open-end wrench or basin wrench. Located in the center of your faucet, between your cold and hot water line, will be another connection for your spray nozzle. This connection is capped off to keep water from flooding your cabinet. Loosen and remove the water line cap with your open-end wrench or basin wrench, turning it counterclockwise.
- 6). Connect the compression nut on the end of your spray nozzle hose to the hose nipple on the underneath side of your faucet. This is the same line that you removed the cap from. Tighten the compression nut with your open-end wrench or basin wrench by turning it clockwise.
- 7). Turn your water back on to check for leaks, and to test your spray nozzle. If you find a leak underneath your sink, check to make sure that your compression nut is tight enough.
