A faucet aerator's numerous tiny pores contribute air to the system, reducing the flow of water. Even less flow is produced by aerators combined with a faucet flow restrictor. You might be tempted to take your faucet flow restrictor out of the aerator and discard it if your water pressure drops too much. Although it is not advised to remove a flow restrictor permanently, it is a good idea to know how to do so in order to clean or replace it. In this article, we are going to see how to remove a flow restrictor from a kitchen faucet.

What Is a Kitchen Faucet Flow Restrictor?

A device called a flow restrictor is made to control how much liquid or gas, like air or water, flows out of a dispenser or faucet. These gadgets can assist in reducing water expenses and are frequently eco-friendly. Flow restrictors, for instance, let people consume less water when taking showers or cleaning dishes.

The amount of water that comes out of a tap is usually determined by the water pressure and the size of the valve. High-pressure taps frequently provide a lot more water than is required for some activities, such as bathing or hand washing. A water flow restrictor, as its name suggests, sets the maximum amount of water that can be released from a tap. It is frequently used in plumbing to regulate the flow of water from faucets and showers.

The two most common ways that flow restrictors are attached to faucets are by screwing them onto the tap or placing them inside the faucet. Aerated nozzles on a large number of them create a fine mist of water instead of a solid flow. There is usually a large selection of flow restrictors for sinks and showers in hardware stores or plumbing supply stores. Flow restrictors are beneficial for a variety of applications as they regulate flow and pressure.

Why Do Kitchen Faucets Have Flow Restrictors?

Reducing water consumption is one of the common uses for kitchen faucet restrictors. Experience, though, suggests that they may have the opposite impact. Let's say you wish to wash the floor and you fill a bucket with water. The time needed to fill the bucket will rise with a flow restrictor, but the amount of water needed won't decrease. You might therefore take care of anything else while the bucket fills rather than waiting for it to fill. Occasionally, you realize after returning to the filling bucket a little too late that water has been wasted since it overflowed into the sink. That wouldn't occur if the bucket filled faster.

How to Locate the Water Restrictor in a Kitchen Faucet

A flow restrictor is a feature of contemporary kitchen faucets that controls the amount of water the faucet uses. Lower flow rates are required by law in numerous nations, including the United States and Canada. A kitchen faucet's flow restrictor is a straightforward device made of a circular plastic disc with tiny holes that let water travel through more slowly. The disc may occasionally get clogged with debris and mineral deposits; in this case, you'll need to remove and clean it. Here's how to locate the water restrictor in a kitchen faucet:

  • Check the spout end of the kitchen faucet. Once you spot a disc with tiny holes in it, you've found the restrictor. The restrictor, which is a component of the aerator, needs to be removed if the disc is invisible

  • To preserve the aerator's finish, wrap painter's tape around the slip-joint pliers' jaws

  • Using the pliers, grasp the aerator and rotate it counterclockwise until it becomes enough loose to be removed entirely by hand. With the pliers, hold the aerator only—not the faucet spout

  • Disassemble the aerator by pulling apart the sections and placing them on the countertop. The rubber washer and the screen should be separated by the flow restrictor disc

How to Remove a Flow Restrictor from a Kitchen Faucet?

All that the flow restrictor is, is an aerator to which a filter or net is attached. Its numerous holes allow more air to pass through and aid in determining the necessary water pressure by dividing the water stream into smaller streams. The flow restrictor provides the water stream a form as it emerges from the faucet sprout and keeps the water from splashing out. It aids in creating a stream of pressure that is uniformly straight.

But because of the minerals, residue, and debris in the water and pipelines, this screen clogs and lowers the water pressure over time. Therefore, in order to solve this issue, we must take the kitchen faucet's flow restrictor off, clean it, and then replace it. We'll demonstrate how to take out a flow restrictor from a kitchen faucet in the sections that follow. To complete this job yourself, though, you'll need a few tools before you start. However, not everything listed here is necessary. If your aerator becomes stuck and won't open with your fingers, it might be necessary. Among these are the following tools:

  • Towel or silicone jar lid (basically to hold the aerator)

  • Adjustable wrench or pliers (in case you can’t open with your fingers)

  • Screwdriver

How to clean a flow restrictor for a kitchen faucet

Step 1: Remove the Aerator

As the first step of faucet flow restrictor removal, using just your hand, try rotating the aerator counterclockwise. It is usually eliminated. However, you can try to remove it with a towel or silicone jar cover if it is slick or you are unable to apply pressure.

You can remove the aerator with pliers or an adjustable wrench if neither of the two situations works. However, bear in mind that applying too much pressure could shatter or scratch your faucet. To keep the faucet safe, wrap the aerator with whatever towel, fabric, or plastic tubing you have on hand, and then remove it with a wrench or pliers. Your work will be finished if you use light pressure.

Step 2: Remove the Flow Restrictor

The dirt particles are visible above the screen once the aerator has been removed. Take out the washer first, then use running water to clean the aerator. To stop any screws or tiny objects from falling out of the sink, cover the holes with a towel or piece of cloth before cleaning.

Now, gently press the aerator's center with your thumb to force the flow restrictor to come out effortlessly. You'll see that there are two screens: one is metallic and is located below the restrictor, while the other is made of some kind of plastic net. However, keep in mind the exact order in which it was placed since you must return it to that same location.

Using a toothbrush, clean the faucet, the aerator, and the netting. The parts are soaked in a vinegar solution for two hours if there is excessive filth or corrosion. This will make cleaning easier for you. You must open the flow restrictor if you are dissatisfied with the cleaning and want to confirm that there is no dirt within.

Using a screwdriver, carefully try to open the nets from the corners to release the flow restrictor. It is crucial to replace everything precisely in the same sequence, so be careful not to break anything and pay attention to the order.

Once it's opened, you may give it a thorough cleaning and replace the nets. Because the parts are highly delicate and you could shatter them, this method is not advised. It's possible that you'll break it on your first attempt and need to get a new one. Eventually, though, you'll learn from your mistakes and not break them the next time around.

Step 3: Connect to the Faucet

Now comes the third and last step to remove flow restrictor kitchen faucet. It's time to reattach the aerator and flow restrictor after cleaning all of its components. However, take off the cloth or towel you put over the sink and turn on the hot and cold water taps before attaching. Run the cold water tap for ten to fifteen seconds, followed by the hot water tap for ten to fifteen seconds. By doing this, the dirt or material that is inside the pipes will be removed. Run the water longer until it turns transparent if you see dirt or brown water coming out of the faucet.

After completing all of this work, you may now connect the aerator to the faucet, attach the parts in the proper order, and turn on the water. You'll observe that the flow restrictor is operating properly and that the necessary water pressure is being obtained. And that's it!
