What Is the Average Flow Rate of Faucets?

A faucet aerator reduces the flow rate. Faucet aerators are often found at the tip of the fixture. They are generally screwed onto the faucet head. Thus, creating a non-splashing stream of water mixed with air. This method of reducing the flow rate does not affect water pressure.

The U.S. Environmental Protection Agency’s (EPA’s) WaterSense program published a specification. This specification labels water-efficient high-performing faucets and faucet accessories. Furthermore, it certifies to use between 0.8 GPM at 20 psi (Pounds per square inch) and 1.5 GPM at 60 psi. And, 0.5 GPM for public installations.

How to Increase Faucet Flow Rate?

You can increase the faucet flow rate by replacing the faucet aerator with a higher GPM model in most cases. But, before going out and purchasing a new one, it helps to find out if the aerator is the real problem. To check this remove the aerator completely and open the faucet to see if the flow is good. If so, then, the problem is with the aerator.

  • Low flow faucet aerator – If this is the problem, you can simply replace the aerator with a higher flow rate unit or remove it completely. However, find out what the maximum legal flow rate allowed in your area while exploring these options.
  • Plugged aerator screen – Over time, mineral deposits and sediments tend to clog up your faucet head. You can unscrew the tip and clean it with vinegar. Use toothpicks to scrape out the particles. If the deposits are too stubborn to be removed, it may be time to replace the faucet head completely.
  • Check shut-off valves 
  • Faucet supply tube
