Tools You’ll Need

  • Screwdriver
  • Adjustable wrench
  • Allen wrench

Step 1 – Remove the Old Faucet

If you still have an old faucet mounted on your kitchen sink, start by turning off the water supply and then removing this faucet.

Step 2 – Install the Sprayer Hose

If you’re installing a pull-down kitchen faucet, feed the flexible spray hose through the faucet’s spout, as well as the hub. Check that the hose and spout are running the right direction. Next, find a clip on the base part of the kitchen faucet. Align and insert the back of the spout into it. It should easily snap in place once it’s connected.

Take the sprayer wand and attach it to the end of the those. You don’t need any tools here. You can just tighten it by hand.

Step 3 – Mount the Faucet

Next, you need to decide if you’ll be using a gasket or not. It depends on your countertop or sink. So if you have 3 already existing holes but installing a single-hole faucet, you’ll have to use a gasket. If you have only one pre-drilled hole in your countertop or sink, you can mount the faucet right on top of it without the gasket.

A lot of the Delta faucets come with the gasket already included in the package. However, not all of them do and you might have to purchase it separately.

Place the gasket over the center mounting holes so that all the holes are covered. Position the kitchen faucet on the sink, while also pushing it through the hole in the sink. If you’re doing 1-hole installation, skip the gasket and just insert the faucet through the single mounting hole.

Next, under the sink, thread the mounting bracket onto the shank. Check that the larger side of the mounting nut is facing upwards. The supply lines should fit inside the bracket.

Check that the faucet and the gasket are positioned properly and then tighten the mounting nut under the sink. You can use an Allen wrench for this. Try not to over-tighten the nut as it can damage it. It should be just enough to hold the faucet firmly in position.

For pull-down faucets, slide the hose weight over the hose and push the end over the faucet outlet. Install the clip to hold the connection in place. Pull down the sprayer to check that there’s nothing catching on under the sink.

Step 4 – Attach the Supply Lines

Look at the ends of each supply line. You’ll see that they are marked red for hot and blue for cold water. Attach each one to its corresponding water supply.

Most of the new faucets come with 3/8″ connection fitting. However, if yours is different, you’ll need to use an adapter.

Thread the supply lines by hand and then you can finish by tightening them with a wrench. Make sure that the supply lines do not cross thread.

Step 5 – Flush the Faucet

The last step of the Delta kitchen faucet installation is to flush out the debris. Any plumbing work usually leaves debris in the plumbing pipes. So before you start using the faucet, it’s important to get rid of it.

First, with the handle in the off position, turn on both the hot and cold water supply. Inspect for any leaks. If you find any, tighten the connections a bit more.

Turn the faucet handle to fully open the water flow. Allow the water to run for about 15-30 seconds, so the water lines could get thoroughly flushed.

Flush also the spray head. Pull down the spray hose into the sink and turn the faucet on, switching from hot to cold water. This will also allow removing any debris that has gotten into the lines.

As you can see, Delta kitchen faucet installation is quite straightforward. Your product will come with a more detailed instructions manual that you should follow. If you’ll have issues or have more questions on how to install a Delta kitchen faucet, you should contact the company’s customer support.
