There may be so many reasons why a person wants to get rid of a flow restrictor. Maybe they are tired of the slow water flow, which makes it take longer to wash dishes or fill a glass of water.

Step-by-Step Instructions to Remove Flow Restrictor From Delta Kitchen Faucet:
Step 1: Disconnect the Head from the Arm
To remove the head from the arm tube connected to the wall, unscrew it. You may be able to do this manually; if not, use a wrench.
Step 2: Remove the Aerator
Try turning the aerator counterclockwise with your bare hands. In most cases, it will be removed. But if it is slippery or you cannot apply pressure, then you can pick up the silicone jar lid and try to remove it.
If both of these situations fail, then you can use an adjustable wrench or pliers to remove the aerator. But remember, don’t apply too much pressure. It may scratch your faucet or even break it. To protect the aerator from scratch, please wrap a cloth or towel around it.
What if my aerator is inside the faucet? This situation applies to newer faucets or brands like Delta. Therefore, to remove the aerator, you must use a tool that can open it.
Step 3: Remove the Flow Restrictor
After removing the aerator, you can see the dirt particles on the top of the screen. First, remove the gasket and clean the aerator in tap water. Before cleaning, put a towel or cloth on the sink to block the hole to prevent the loss of screws or small objects. Now, gently push the centre of the aerator with your thumb, which will force the restrictor to enter easily.
You will notice that there are two screens below and above the restrictor; one is metal, and the other is some kind of plastic. But remember where it is placed because you must put it back in exactly the same order. Take a toothbrush to clean the net, aerator and faucet. If you are not satisfied with the cleaning and want to make sure that there is no dirt in the restrictor, you must open it and check.
Step 4: Reattach the Faucet
After cleaning the aerator, restrictor and all its components, it is time to put them back in place. But before installation, please remove the towel or cloth placed on the sink and then turn on the hot and cold water faucet. First, run the cold water tap for 15-20 seconds, and then run the hot water tap for 15-20 seconds. This will remove debris or dirt present in the pipeline. If you find dirt or brown water coming out of the faucet, you can run the water for a longer period of time until it becomes transparent.
After finishing all the steps, now you can install the parts according to the location and connect the aerator to the faucet and drain the water. You will notice that the restrictor is working properly, and you will get the required water pressure.
