How To Remove The Flow Restrictor From A Delta Kitchen Faucet

Are you having trouble with your Delta faucet’s water flow? It’s likely that the flow restrictor is clogged and needs to be removed.

Don’t worry, this project is not as daunting as it seems! In this guide, you’ll learn how to remove the flow restrictor from your Delta kitchen faucet quickly and easily.

All you need is a few basic tools and a little bit of time. Let’s get started!

Gather the Necessary Tools

To get the job done, you’ll need some tools; so gather ’em up and get ready to go!

First and foremost, you’ll need to obtain some supplies. Select a wrench that can easily fit in the tight spaces around the faucet. You’ll also need an adjustable wrench to help loosen the fittings. You’ll also need a small pair of pliers to help remove the flow restrictor. Lastly, you’ll need an old toothbrush to help clean up any debris.

All these tools are necessary to complete the job. Make sure you have all the tools you need before you begin.

Locate the Flow Restrictor

Locate the piece inside your faucet that’s causing the water pressure to be low – it’s time to find out what’s restricting the flow!

There are a few parts to identify in order to assess the pressure. Inside your faucet, there should be a small disk-shaped object. This is the flow restrictor, and it may be held in place by a nut or screw.

If you can’t easily spot it, you may need to disassemble some parts of the faucet in order to gain access. Use a flashlight to get a better view of the inner workings of the faucet.

With the proper tools and a little patience, you should be able to locate the flow restrictor.

Remove the Aerator

Now that you’ve found the piece that’s causing low water pressure, it’s time to take it out.

Unscrew the aerator from the end of the faucet using an adjustable wrench. Make sure to keep the aerator upright as you unscrew it in order to avoid any splashing. If the aerator is stuck, use a pair of pliers or a rubber band to unscrew it. Be careful not to over tighten the wrench and damage the aerator.

Remove the aerator and inspect it for any small pieces, such as the flow restrictor, that may be lodged inside. Once the aerator is removed, inspect it to find the flow restrictor.

The size of the aerator will determine the size of the flow restrictor. If the aerator is smaller than the size of a nickel, then it will have a small flow restrictor. If the aerator is larger than the size of a nickel, then it will have a larger flow restrictor.

Carefully remove the flow restrictor from the aerator. If it is stuck, use a pair of pliers or a rubber band to remove it.

Unscrew the Flow Restrictor

Unscrewing the restrictor from the aerator will help restore the water pressure.

To begin, check the compatibility of the restrictor to the aerator and inspect the seals to make sure they’re in working condition. If the seals are good, you can start to unscrew the restrictor.

Use pliers to grip the restrictor and apply steady, consistent pressure to loosen it. Once it’s loose, you can carefully take it off the aerator and inspect it for any damage.

If it’s damaged, you should replace it with a compatible one. Be sure to keep the removed restrictor for future use.

Once the restrictor is off, you can test the faucet to ensure that the water pressure has been restored.

Clean the Flow Restrictor

Cleaning the restrictor is an important step to help maintain your faucet’s water pressure. Let’s get started!

To clean the restrictor, you’ll need to replace the parts in the aerator. First, use a pair of pliers to unscrew the aerator from the faucet. After it’s loosened, you should be able to remove the aerator.

Then, rinse it off to remove any dirt or grime.

Once the aerator is clean, you’ll need to remove the restrictor. To do so, look for the small plastic disk at the end of the aerator and carefully remove it. If it’s stuck, you can use a flathead screwdriver to help remove it.

Once it’s off, you can rinse it off with water to remove any excess dirt or debris.

Finally, you can reinstall the aerator and enjoy your faucet’s improved water pressure.

Reassemble the Faucet

Gently reassemble your faucet with the parts you just cleaned, and you can soon enjoy the improved water pressure.

Start by replacing the parts that were removed as part of the cleaning process:

  • Place the flow restrictor back into the nozzle and make sure it’s securely in place.
  • Install the rubber seals that were removed earlier.

Once the pieces are back in place, carefully screw the nozzle back onto the spout. Make sure it’s securely tightened, and that the seals are properly installed.

Finally, attach the handle, and you’re done! With your faucet reassembled, you can now enjoy the improved water pressure.

Test the Faucet

With your faucet reassembled, it’s time to test it out and see the improved water pressure for yourself.

There are a few methods you can use to test the flow rate adjustment. First, fill a pot with water and then turn on the faucet. Measure the time it takes to fill the pot and compare it to the time it took to fill the pot before you removed the flow restrictor.

Alternatively, you can measure the water pressure coming out of the spout to see if it has increased. You can also pour a glass of water to see if it’s now flowing more quickly.

Once you’re satisfied with the water pressure and flow rate, you can be sure that you have removed the flow restrictor successfully.

Frequently Asked Questions

Is there a risk of damaging my faucet if I try to remove the flow restrictor?

Removing the flow restrictor from your Delta kitchen faucet can be tricky and potentially damaging to your faucet. If you try to remove it incorrectly, it can affect the water pressure and flow rate, which can lead to costly repairs.
