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. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
Is higher GPM better for shower head?
One person who showers 10 minutes per day with a 2.5 GPM shower head uses 9,125 gallons of water per year. Switching to a 2.0 GPM shower head saves more than 1,825 gallons of water and $25 per year in water and energy costs. Those numbers jump to 7,300 gallons and $100 in savings for a family of four.
Is 2.5 gpm shower head good?
Standard shower heads use 2.5 gpm, but to earn the WaterSense label, a product must use no more than 2 gpm and still meet strict performance requirements. The EPA estimates that the average family could save 2,900 gallons of water per year by installing a WaterSense-labeled shower head.
Is 1.5 gpm shower head enough?
Shower Head Flow Rates Some states, such as California, New York, and Colorado restrict flow to 2.0 GPM. Many modern low flow shower heads deliver only 1.5 GPM. A quality low flow shower head will feel good at both high and low water pressures.
Does GPM affect water pressure?
Water Flow Rate is how much volume of water is being delivered in a certain amount of time – most often calculated at gallons per minute, or gpm. This can often lead to lower “water pressure” because the flow rate simply can’t keep up.
What shower head has the most gpm?
Across the United States, 2.5 GPM is the maximum flow rate allowed for shower heads. That said, some states have even harsher restrictions. In Colorado, New York, and California, 2.0 GPM is the maximum allowed.

Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute. If your current shower head was made in the 1980’s or 1990’s, its flow rate could be 3.5 GPM or more!.
Does higher GPM mean more pressure?
GPM stands for gallons per minute. It refers to the flow rate or the volume of water that moves through the pressure washer’s nozzle every minute. Think of GPM as rinsing power. The higher a pressure washer’s GPM, the quicker you can wash a surface clean.
How can I make my shower water pressure stronger?
How to increase water pressure in the shower Clean your shower head. Replace the shower head. Install a shower pump. Installing a pressurised unvented cylinder. Install an electric shower with a cold water accumulator tank. Install a power shower.
What is a good water pressure for a shower?
While you don’t want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that’s between 60 and 70.
What is typical shower flow rate?
In an average home, showers are typically the third largest water use after toilets and clothes washers. The average American shower uses 17.2 gallons (65.1 liters) and lasts for 8.2 minutes at average flow rate of 2.1 gallons per minute (gpm) (7.9 lpm).
How do I increase the GPM on my shower head?

How do I know if my shower head is low flow?
A quick tip to find out if your current shower head is wasting water is to put a one-gallon container in the shower, turn on the water, and count the time it takes to fill up completely. If it fills up in 15 seconds, the flow rate is about 4 gpm. If it’s full in 10 seconds, the flow rate is closer to 6 gpm.
Are all shower heads low flow?
Myth 1: Low-Flow Shower Heads Don’t Have Enough Pressure The greater the pressure pushing water through the showerhead, the greater the volume of water forced out. Today’s standard for low-flow heads is set at 2.5 gallons per minute, but many showers still flow at 4 gallons per minute.
Do all new shower heads have flow restrictors?
The National Energy Act requires that shower head manufacturers install a flow restrictor or flow controller in shower heads.
Is 2.5 or 1.75 gpm better?
If you’re looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992.
Is higher GPM better?
The higher the GPM the faster it will be to clean large surfaces.
Is 2.5 gpm low flow?
Unfortunately, there is no firm definition of low-flow, but it’s generally accepted that anything using 1.5 gallons per minute (gpm) or less is considered “ultra low flow,” while anything using 2.5 gallons per minute to 1.5 gallons per minute is considered “low flow.” Nowadays, thanks to standards set by the government Jan 18, 2018.
How do you measure shower GPM?
Instructions for measuring the water flow rate at a faucet or shower Turn on the water. Time how long it takes to fill the container using your stop watch or phone (in seconds). Divide 60 by the number of seconds it took to fill your container (ie. The result is the flow rate of that application in gallons per minute.
