How to install a pull-out style kitchen faucet in your home.
There is a new trend in kitchen fixtures known as “Pull-out” faucets that have a spray hose hidden inside a sleeve that looks like a traditional spigot. These faucets are great for filling pots, cleaning dishes, and food preparation and cleaning. These faucets are not much more difficult to install than traditional units.
Tools and Supplies
Flat and Phillips screwdriver
Braided supply lines
Escutcheon plate, if needed to cover holes in the sink or countertop when replacing a three-hole faucet
Most plumbing fixture hook up the water lines with a pair of compression fittings that seal without the need for soldering, pipe dope, or even Teflon tape.
Many faucets come with flexible, braided water supply lines flexible to connect to the shutoff valves, but these are usually too short to connect directly to the valves. While most standard faucets require additional lengths of braided supply line to connect the faucet to the valve, pull-out faucets usually have enough hose to compensate for this. It is a good idea to read the installation instructions before you begin taking your sink apart to make sure that you have all of the parts you need.
Most pull-out faucets have a single control for hot and cold attached right to the spout, so they only need one hole cut through the rim or counter at the back of the sink. But if you're replacing a fixture with two separate handles for hot and cold, you'll discover that you're left with three or four holes in your sink. If this is the case, you'll need to cover the holes with escutcheon plates. They make rectangular ones for the three-hole cutout and a small round one for the old sprayer. Many pull-out faucets include matching escutcheons for this purpose, or if you don’t like the look, you can replace the sink too.
1. Removing the old faucet
Turn off the hot-and cold-water valves under the sink and keep track of which one is which. Turn the water on at the faucet and if any comes out, the valves aren't holding and you will need to shut off the water at the water main.
Use a small bucket or pan to catch any water remaining in the supply lines. Loosen the nuts connecting them to the valves with an adjustable wrench.
Use a basin wrench to reach up underneath the counter and loosen the nuts holding the faucet and handles at the top of the sink. Remove the old faucet. A basin wrench is a specialized tool specifically for installing and removing faucets. It has an adjustable square handle with a U-shaped jaw on the end.

2. Removing Supply Lines
After loosening the hex-nut that connects the water-supply line to the shut-off valve, gently pull up on the supply line to separate it from the valve. If the line is copper tubing you may need to bend the line slightly to free it from the valve. Be careful not to twist the line too much or you might crimp the copper pipe coming from the wall.
3. Position the new faucet
Connect the hose to the spray head and thread the hose through the spout.
If it isn't already attached, mount the temperature control handle to the faucet, using the screws and tool provided with the kit.
There should be a black rubber ring over the hoses and supply line that needs to be slid onto the faucet stem. Slide the escutcheon plate over the hoses at the base if you are using one. Thread all the hoses through the center hole in the sink rim. Depending on the installation instructions, you may need some plumber's putty under the faucet to seal it to the sink.
4. Attaching the faucet to the sink
From underneath the sink, slide a series of washers over the hoses. Usually there is a triangular plastic washer, a fiber washer, metal washer, and lastly a circular nut over the hoses.
Push the nut assembly up to the underside of the counter. Screw the circular nut onto the large threads of the faucet stem. Use the basin wrench to tighten it. Many times you screw this clamp to the triangular nut to prevent it from working its way free.
You may need a helper to hold the faucet in place while you install the washers and locking nut, or you can remove the sink and work on the floor.
5. Connecting the Water
If your faucet has rigid tubing, connect braided lines to its hot-and cold-water supply lines. Most manufacturers color code the hot with a red end cap and blue for the cold. Attach the supply lines to the correct valves.
Loop the loose end of the spray hose up and connect it to the third line coming from the faucet. Then, use an adjustable wrench—or any smooth-jawed wrench—to tighten the compression nuts connecting the supply line to the shut-off valve.
6. Tighten fittings
When tightening the compression nut on the supply line, stop turning just when it begins to feels tight. Place a second wrench on the small nut located just above the compression nut, and give the compression nut a quarter turn. Using two wrenches will keep the supply hose from twisting as you tighten the compression nut.
Do not use Teflon tape, Teflon paste, or other chemicals on compression threads, as they can loosen the fitting causing a leak.
7. Hose weight
Pull-out faucets have a weight in the middle of the hose that limits how far you can pull the hose and helps lower it back into the spout. They are usually about 15 inches down from the underside of the faucet. The weights come in two parts and screw together over the hose.
Pull the faucet out of the spout to test the distance and the retracting action. Move the weight if necessary. Be careful not to put it so far down on the hose that it rests on the floor of the cabinet, or the spray head will not go all the way back into the spout.
8. Cleaning the Aerator
Turn on the hot and cold supply valves and look for leaks at every connection. Tighten any connections that are found to be leaking.
Remove the aerator at the tip of the faucet spray head. Turn on the faucet to let water flush through the pipes and the spout, then replace the aerator.
Since these types of faucets usually receive more abuse. It is a good idea to purchase high-quality brass fixtures and not chrome plated plastic. Hopefully this will provide you with some guidance for installing a pull-out faucet in your kitchen.
