    How To Install A Delta Kitchen Faucet

    Installing a new Delta kitchen faucet is not too difficult when you have the right tools and instructions to follow. Every faucet has slightly different installation instructions based on the unique features of the model but most faucets are installed in essentially the same way. This example is a Delta Leland pull down kitchen faucet.

    When picking out a faucet you can decide how many holes you want to fill and how you want it to look. The installation instructions will change slightly depending...MORE on whether you want a 1, 2, 3, or 4 hole finish.

    Install The Spout

    The first step when installing a Delta kitchen faucet is to install the spout first. Thread the mounting screws into the mounting nut making sure they are only a few threads in. Put the foam gasket on the spout and push the spout through the desired hole in the sink.

    From the bottom screw the mounting nut and metal washer hand tight all the way up to the underside of the sink. When you have hand tightened the mounting nut as much as possible use a screwdriver to tighten the screws. The...MORE combination of mounting nut and screws will completely secure the spout to the sink.

    Note: If the foam gasket is not enough to secure the faucet you can also use silicone under the spout to help seal the fixture.

    Install The Valve

    Valve assembly is the second step when you install a Delta kitchen faucet. Slip the foam gasket up around the tubes and position it in the grove at the base of the valve. Push the tubes through the sink hole while holding the gasket in place. Center the valve by aligning the tip of the ā€œvā€ (or triangle) on the top of the valve straight out to face the sink.

    Use the mounting bracket and nut from under the sink and tighten using the tool provided or your own socket wrench. As you tighten, make sure...MORE that the valve stays straight facing the direction it needs to because sometimes it can move a little when tightening.

    Install The Sprayer Hose

    Hose installation for a pull-down sprayer is the next step. Install the sprayer head onto the threaded end of the hose and hand tighten only. Attach the hose guide onto the other end of the hose and feed it through to the underside of the sink. Remove the hose guide and feed the weight onto the hose.

    Connect the sprayer hose to the valve hose by pushing the ends of the hoses together. Secure them by installing the clip to hold them in place. Pull the sprayer out and check that when you do the...MORE sprayer hose does not catch on anything under the sink. If the hose gets tangled up during the installation it can make it difficult to use the sprayer.

    Connect The Water Lines

    Connect the hot and cold water lines. The size of the faucet hoses can vary, but many newer faucets come with 3/8" hoses that need to be connected to 3/8" angle stops. To connect the water lines just thread the flex lines by hand to make sure they do not cross thread and then finish tightening them up firmly with a wrench or pliers.

    If you do not have 3/8" angle stops I recommend changing them rather than using an adapter to connect to the existing angle stops.

    Install The Faucet Trim

    The next step is to put the trim and handle on. To put the valve trim on just screw it on by hand. Next, slip the handle onto the valve and tighten it with the set screw. After the handle and set screw are tight, you can put the button on that covers the set screw.

    Check For Leaks

    Make sure the valve handle is in the off position and turn the angle stops on from under the sink and check for leaks. Before using the faucet it is a good idea to flush out the sprayer hose. To do this pull out the sprayer head and unscrew it from the sprayer hose making sure to hold on to the sprayer hose. While holding the sprayer hose into the sink turn the faucet on to the cold and hot sides allowing the running water to flush out anything that may have gotten into the lines. After about a...MORE minute you can turn the water back off and screw the sprayer head back on.

    At this point, it is a good idea to test for leaks underneath the sink again. I also recommend checking for leaks several hours after the installation and once again the next day. Even a very small water leak under the sink can lead to mold and cabinet damage over time.
