Delta kitchen faucets are more or less the industry standard, and they offer an excellent value, especially if you’re looking for a kitchen faucet with a built-in sprayer.

But what happens if your faucet sprayer starts to leak, gets worn out, has a faulty diverter or you just want to remove the sink sprayer entirely and have a cleaner-looking kitchen sink?

Don’t worry, we’re here to help. We’re going to go through everything you need to know about removing the kitchen faucet sprayer from your Delta faucet, whether you have a pull-down, pull-out, or side sprayer design.

First, we’re going to give you a little background info on how exactly your spray hose works so that your DIY plumbing job goes a little smoother.

Understanding How Your Faucet Sprayer Works

To start, we have to go into a little detail about how your Delta faucet sprayer actually functions, so you know what you’re looking at when you’re staring at the underside of your sink.

Under the basin of your sink, you’ll see hot and cold water supply lines which are connected to the faucet itself which is how the water comes out of the primary spout. 

Linking the faucet to the sprayer head is a little valve called a diverter, which allows the water to move through the connecting hose to the spray head only when the sprayer is activated. These are typically only found on kitchen sinks and larger commercial-style sinks like what you might have in a garage. 

These hoses usually use quick-connect fittings instead of threaded connectors, which make them easy to install and remove without calling a plumber. Which is good for us! We love it when home improvement is DIY-able.

If you find your hose is leaky, then it’s probably due to hard water leaving mineral deposits around the gasket and o-rings, which means it’s time to install a new hose

Disconnecting The Sprayer Hose From Your Delta Faucet

1: Turn Off The Water Supply Lines

Turn off the water supply at the shutoff valve and remove anything that might make it difficult to get under your sink. 

2: Gather Up Your Tools

You will need:

  • A flathead screwdriver
  • A basin wrench (depending on your sink setup)
  • An adjustable wrench
  • A flashlight
  • A small bucket or something similar to catch excess water

3: Drain The Water From The sprayer

This one is pretty easy, just activate the sprayer and let the remaining water drain down the sink.

4: Remove The Old Hose

You will need to look up the part number for your hose assembly and see if it has a quick-connect or threaded adapter, or you can just peek under the sink. 

The quick-connect adapter will usually have a black plastic collar on it that you simply pinch at the bottom and the old hose will come free. Certain models will be similar, but will just need to be pushed upwards and then pulled down to disconnect.

Rarely, there will be a metal clip that you will need to carefully remove with your screwdriver. Keep this little clip as you will need it when you reattach the new hose.

Also, if you have a pull-out kitchen faucet, there will be a weight on the hose that you will need to put on the new one.

If you have a threaded adaptor, you will need to use the basin wrench and your adjustable wrench to remove it. This is where you will need the small bucket or similar, which you will place underneath the hose to catch the water in the line.

5: Remove The Sprayer Head And Pull Out The Hose

Next, we have to remove the sprayer head. This is pretty easy, you just have to turn the slide nut counterclockwise and set the sprayer head aside.

If you find that it’s difficult to unscrew, soak the sprayer head in a mixture of 1:1 vinegar and water for about an hour, which will loosen the mineral deposits which are likely making the sprayer head difficult to remove.

Now, just pull the hose up and out and you’re all done!

Installing A New Kitchen Faucet Hose

Once you’ve done all that, simply reverse the process to install the new hose. Once you’ve done that, simply run the faucet for a little bit and check for any leaks to double-check your work.

If there is still a leak, make sure you’ve tightened everything properly and ensure that you’re not dealing with user error. 

If you did everything right and there’s still a leak, you may need to apply a silicone-based sealant somewhere, call a professional plumber, or just check your warranty info for the faucet itself as the leak may be due to a manufacturing defect.

Final Thoughts

Disconnecting and replacing a sprayer hose for a Delta faucet (or Moen, or a similar common brand) is usually not too terribly difficult. You should now have all the knowledge you need to handle this little bit of DIY plumbing on your own, all you need are some basic tools, and the info above and you should be good to go!
