Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions. Beyond intentional flow restriction, new installations can sometimes have reduced flow if the lines are not flushed prior to installation of aerators or shower heads.
Flow restrictors for faucets are an integral part of most aerators and it is generally not possible or desirable to remove them. Our H2Okinetic showering devices are specifically designed to operate most efficiently at the flow rate controlled by the flow restrictor.
All kitchen sink faucets should comply with federal standards for a maximum flow rate of 2.2 gpm (8.3 lpm); a flow test does not exceed 0.4 gal.
A water flow restrictor is usually a flat, circular, plastic piece. The center of the restrictor is shaped like a star, or similarly shaped, and comes in a variety of colors.
Flow restrictors are usually found in the neck or threaded end of the shower head exposed when the shower head is removed from the shower arm as shown in the image below. They would appear in the opening of the aerator when it is removed from a lavatory or kitchen faucet.
It's worth checking the restrictions in your area before tampering with your showerhead. In addition, removing the flow regulator will also increase your overall water usage and the amount of power used for heating water, which is bad for your wallet and the environment.
Low water pressure in sink faucet
Clogged aerators and clogged cartridges are two of the most common causes of low water pressure in a sink.

What is an Aerator, otherwise known as a Perlator or Flow Restrictor? Cobra explains the difference between various types of taps. An aerator tap is also known as a perlator tap or a flow restrictor.
Why does my faucet have low water pressure? Remove the aerator or showerhead and make sure the debris screen is not clogged. Additionally, flushing the system properly will help to reduce the possibility and frequency of occurrences.
Removing a flow restrictor is illegal according to the US Energy Policy Act of 1992, which limits the maximum shower water flow rate to 2.5 gallons per minute (GPM).
In most cases, the easiest way to increase a faucet's flow rate is by replacing the aerator. Try looking for a higher gpm model to allow for more gallons per minute. If you live in a low water pressure area, an aerator designed to restrict water flow might be reducing the flow too much.
Removing the water restrictor from your showerhead can also improve water pressure. Removal might also clear out mineral build-up around the restrictor. It's fine for you to remove one if you live in an apartment unless otherwise stated. Note that your water bill may increase after removal.
Clogged aerator screen
The aerator is the first to check when a faucet has low water pressure. Most faucets have aerators at the base or inserted inside the spout. Sediments, mineral deposits, or small debris can clog the aerator over time, which results in low water pressure.
Fixes for Low or No Water Pressure in Bathroom Sink
Remove and clean the faucet aerator thoroughly, or replace it with a new one. Remove and clean the flow restrictor, increase the size of the flow restrictor hole, or remove it entirely and replace the aerator without replacing the flow restrictor.
Find the spigot closest to your source of water. Make sure all the taps and other water uses are turned off in your house. Now turn on the spigot and see how long it takes to fill the bucket. Dividing the number 60 by the time to fill the bucket will give you the gallons per minute number.
According to federal regulations, all kitchen and bathroom faucets should have a maximum flow rate of 2.2 gallons per minute (gpm) at 60 psi (pounds per square inch) of pressure; in California and Georgia, maximum flow rates are further restricted to 2.0 gpm (California will eventually be restricted to 1.8 gpm).
The adjustment screw raises and lowers the water pressure, but before it can be adjusted, you need to loosen the lock nut below it. Loosen the lock nut by half a turn with the crescent wrench. Turn the adjustment screw counterclockwise to lower the pressure or clockwise to raise the pressure.
In addition to saving energy, flow restrictors also help conserve water. You can save hundreds of gallons each year by reducing the flow of water. This measure not only helps conserve water but also reduces the stress on your plumbing system and can help you avoid costly repairs.
