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.
How much water per minute does a faucet use? The average flow rate for faucets is between 1.0 gpm and 2.2 gpm. In the US, the maximum flow rate for kitchen and bathroom faucets is 2.2 gpm at 60 psi. In more environmentally regulated areas, the maximum flow rates are further restricted.
Kitchen faucets may temporarily increase the flow above the maximum rate, but not to exceed 2.2 gallons (8.3 L) per minute at 60 psi, and must default to a maximum flow rate of 1.8 gallons (6.81 L) per minute at 60 psi.
Kitchen Sink Faucets - All kitchen sink faucets shall comply with federal standards for a maximum flow rate of 2.2 gallons per minute (gpm) (8.3 lpm). A flow test does not exceed 0.4 gal.

While it is possible to remove flow restrictors from shower heads, we strongly advise against it for several reasons. Flow restrictors for faucets are an integral part of most aerators and it is generally not possible or desirable to remove them.
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.
The most common causes of low water pressure in a kitchen sink are a clogged aerator or a clogged cartridge.
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. The aerator is the tip of the faucet that the water comes out of, while the cartridge is found underneath the sink handle and enables you to stop and start the flow of water.
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.
A faucet aerator reduces the maximum water flow rate from your faucet. The average kitchen faucet aerator has a flow rate of 2.2 gallons per minute, according to Home Water Works. All new faucets sold since 1994 are required to have flow restriction in order to conserve water.
You should have 2 valves made of plastic or metal attached to your faucet to control hot and cold water separately. Turn the valves counterclockwise to open them and increase water pressure. If you have low water pressure, make sure the valves are in the open position.
What does a flow restrictor look like? Before you remove the flow restrictor from your shower head, you need to know what it looks like. 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.
To compensate for variations in pressure, flow restrictors decrease the volume that water flows through when pressure increases. Likewise, the opening will widen when pressure decreases.
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.
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.
Effective from 1 January 2023, California will ban the sale and manufacture state‑wide of endpoint devices intended to convey or dispense water for human consumption that leach more than one microgram of lead calculated in accordance with the 2020 NSF International Standard.
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.
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).
Now, several important terms linked to flow rate that you need to know, as well. Here are they: Aerator – This is a mechanism that controls the flow rate of showerheads and faucets. GPM – GPM, or gallons per minute, measures how many gallons flow from the water fixture every minute.
A low-flow sink faucet must not exceed a maximum of 1.5 GPM. A low-flow toilet must use no more than 1.5 gallons per flush (GPF).
