GPM means Gallons Per Minute. Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute. … This means no more than 2.5 gallons of water should flow out each minute. The GPM flow rate for shower heads has decreased over time.

What is a good gpm flow rate?

How do you calculate gpm flow rate?

The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.)
