What Is The Average Flow Rate Of A Faucet?

The average flow rate of a faucet is between 1.0GPM and 1.5GPM. GPM stands for ‘Gallons Per Minute.

According to studies, people normally open the tap to a flow rate between 1.0GPM and 1.5GPM. However, all faucets are subject to maximum flow rates of 2.2GPM at 60 psi. Psi here stands for Pounds Per Inch. 

According to the Federal Standards, 2.2GPM is also the maximum flow rate that has been allocated for faucets. However, you can get the flow rate reduced to as low as 0.8GPM. 

You can do this without affecting the water pressure of your faucet. It would also be one of the best ways to reduce the amount you pay for your water bill. 

So we now know about the flow rate of most faucets. That means that the faucets in your home are likely having a flow of 2.2GPM or below. 

However, you cannot just get up and guess something like this. We are now going to look at how you can measure the flow rate of your faucet so that you will know exactly the flow rate you are dealing with in your home.

  3. Now, turn the faucet off after 10 seconds.
  4. Now, measure the amount of water that has been collected in the container and convert the measured value into gallons. After obtaining the amount of water in the container, multiply it by 6. The number you get will then be the GPM of that particular faucet you just tested.

So that is how you can measure the flow rate of the faucets in your home. As you can see, it is quite a straightforward procedure that can be carried out by anyone at all.

There is something in the faucet known as an aerator, and it is responsible for reducing the faucet’s flow rate. 

The aerator of a faucet is usually located at the tip of the fixture, and it is usually screwed onto the head of the faucet. This creates a non-splashing stream of water that is mixed with air. 

When the faucet’s flow rate is decreased in this manner, it does not affect the faucet’s water pressure.

To decrease the flow rate of your faucet, all you have to do is screw the head of the aerator to your desired level.

A specification published by the U.S Environmental Protection Agency’s WaterSense program labels recommends high-performing faucets.

The publication also certifies that using between 0.8 GPM at 20 psi and 1.5 GPM at 60 psi (for home installations) while 0.5 GPM is suitable for public buildings.

So that is how to quickly decrease the flow rate of the faucets in your home.

How To Increase Faucet Flow Rate In Your Home

However, if you feel like paying more for your water bills than what you are currently paying, you can quickly increase the faucet’s flow rate. 

To increase the flow rate of your faucet, you will replace the aerator of the faucet with a model with a higher GPM (Gallons Per Minute). 

However, before you get up to go and purchase the new aerator, you should first try to find out if the current aerator is the cause of the low flow rate problem or not. 

To make sure that is not the case, remove the aerator from the faucet to see if the faucet’s flow rate is reasonable. 

If the standard flow rate is reasonable, then the aerator is the problem, and you can go ahead and purchase a new one.
