Here are the steps that you will need to follow to install a new kitchen sink in your home.

Step one:
Kitchen sink faucets will sometimes require some assembly before mounting the sink to the faucet. If this is the case, you will need to follow the manufacturer's directions. If your new kitchen faucet has a pullout sprayer faucet, you will need to thread the sprayer through the faucet body before you can attach it to the sink.

Step two:
Place the rubber gasket between the base plate of the faucet and the sink top. This will be used to create a watertight seal. If no gasket is provided, you will need to pack the cavity of the faucet with plumber's putty. Once you have packed the cavity, you will need to insert the faucet body through the holes in the sink top.

Step three:
Next, you will need to thread the mounting nuts that are provided onto the faucet shafts. Next, you will need center the threaded shafts in the sink's holes and then tighten the nuts firmly.

Step four:
Most new faucets will come with a special long socket that can be used to help tighten the mounting bolts. In the socket, there is a hole that accepts the shank of a screwdriver, guiding it as you tighten the nuts. If you are installing your new kitchen faucet on a sink that is already installed you should follow this method.

Step five:
If you are installing a pullout sprayer faucet or even a faucet with a separate sprayer, this is the time to connect the sprayer to the faucet body. You will want to read the specific instructions to see if you need to use pipe-wrap tape for this connection. To tighten the connection you will need to use an adjustable wrench.

Step six:
Most of the faucets that have pullout sprayers or even separate sprayers come with a counterweight that attaches to the sprayer hose. The weight is used to help retract the hose back into the sink cabinet after you have used the sprayer. You will need to follow the manufacturer's instructions on where to secure the weight. When securing the weight be careful not to crimp the hose as you attach the weight.

Step seven:
Hook up the faucet's hot and cold supply lines to the water supply shutoff valves underneath the sink. You might need to gently bend the copper tubes that are coming out of the faucet for better access and to connect flexible supply tubes to them. Wrap a couple of turns of pipe-wrap tape around the threaded nipples on the valves and then connect the tubes. Using an adjustable wrench tighten the nuts.

Step eight:
Remove the aerator from the faucet so that you can flush the lines. This will ensure that there isn't any debris inside the lines that can clog the lines and reduce the water flow. For a standard faucet, unscrew the aerator at the end of the spigot and let the water run for a minute or two. For a pullout sprayer faucet, the aerator is housed in an inlet in the sprayer head. What you will need to do is unthread the hose, remove the aerator, and flush the line.
