However, if any of these parts do not work properly up to the optimum level, then you may have to face some issues while using them. Here in this article, we will be talking about the flow restrictor, which is mainly responsible for regulating water flow too much extent. 

Generally, flow restrictors are installed in most of the kitchen faucets, which prevents the overuse of water and ultimately helps to minimize the wastage of water. These flow restrictors are complemented with aerators which further help to control the water flow. 

However, sometimes the water flow becomes too low, which is not enough for doing the daily chores like dishwashing or cleaning the kitchen.

If this is your case, then you have to remove the water flow restrictor to get the desired water flow. But how to remove it? 

Do not worry as we will give you a detailed explanation about all the steps you need to follow so that you can easily remove the water flow restrictor and carry on your cleaning activities without any stress.

So without any more delay, let us take a look at the steps. But before that, it’s necessary to know about the instruments required. So, first of all, let us see the things required before starting the process. 

Instruments required

  • Screwdriver 
  • Towel 
  • Adjustable wrench

What are the steps to remove the flow restrictor from the kitchen faucet? 

Generally, after prolonged use, some dust particles and sediments may get collected in the restrictor, which reduces the water flow coupled with many other reasons. Now, to get back to the optimum rate of flow, you have to remove these small particles and clean the restrictor properly.

But to achieve this first of all you have to know how to remove the water flow restrictor. Read along to get a roadmap for successfully removing the flow restrictor without calling the plumber. 

1.Cover the sinkhole

We will start with the precautionary measure that is absolutely essential before moving on to the next step. Here, you have to use a towel to cover the sinkhole so that the small screws do not get lost by falling through the holes.

These screws are extremely important for fixing the flow restrictor back to normal position after the cleaning is done. So you cannot afford to lose them at any cost, which is the best way to prevent the loss of screws. 

2.Close all the water valves

Now, moving on to the next step, here you need to close the water valves situated under the sink. Usually, there are separate valves for hot water and cold water, and you have to close both of them before starting the process. After closing the valves, you should open the faucet once to drain the remaining water and equalize the air pressure. 

3.Remove the aerator

It is a very easy step in which you need to remove the aerator simply by using your hands and turning it in an anti-clockwise direction.

However, if you feel it’s too tight to rotate, then you can take the help of an adjustable wrench. But while using a wrench, be careful as it may damage the faucet.

So try to cover it with a rubber band before holding it with the adjustable wrench. Now you can easily pry off the aerator by just turning it anti-clockwise. 

However, if the aerator is deeply embedded and cannot be removed using a wrench, then you have to use some advanced tools which are made explicitly for removal. There is no need to panic as you can get this removal tool from your nearest plumber shop or can also buy it online.
