Easiest way to measure flow rate is to get a bucket to collect water coming out of the shower head, however, if you want to compare different shower heads make sure you calibrate for incoming water pressure. Time it for 1 min and measure the volume or weight of the water that is collected.
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.
Before the restrictions, shower heads typically used 5.5 gpm. Restricting the flow to 2.5 gpm led to a new generation of water-saving shower heads. The change in flow rate is particularly noticeable if you go from a shower head produced before 1994 to a modern model.
Often, you can determine whether your showerhead is low-flow by reading any labels printed around the rim. If your showerhead is labeled 2.5 GPM or less, you have a low-flow showerhead. Any showerhead labeled 2.6 GPM or above is a high-flow showerhead.
When it comes to Shower Heads, you'll typically find 2.5 GPM, 2.0 GPM, 1.8 GPM and 1.5 GPM. 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.
Absolutely. Many low-flow shower heads still deliver a powerful, satisfying shower even with a reduced flow rate. If you're looking for a better showering experience that also helps you save water, we recommend checking out the 1.8-GPM shower head model from hai.
Remove the Water Restrictor
Removing the water restrictor from your showerhead can also improve water pressure. Removal might also clear out mineral build-up around the restrictor. It's fine for you to remove one if you live in an apartment unless otherwise stated. Note that your water bill may increase after removal.
Know the Impact. 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.
That's a common misconception. A lower flow rate does not mean that your shower will have less pressure. Water flow (gpm) refers to how much water is coming out, not how fast or how hard it's coming out.
A 2.5 gpm shower head will have a better pressure and shower experience than a 1.5 gpm shower head. A 1.8 gpm shower head would have a better pressure and shower experience than a 1.0 gpm shower head. Another drawback of low flow shower heads boosting the pressure is the temperature instability.
Find the spigot closest to your source of water. Make sure all the taps and other water uses are turned off in your house. Now turn on the spigot and see how long it takes to fill the bucket. Dividing the number 60 by the time to fill the bucket will give you the gallons per minute number.

Low pressure in a shower can be caused by several issues such as a clogged showerhead, a worn-out mixing valve, closed valve, leaking pipe, or even a faulty water heater.
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.
Water pressure is measured in psi, or pounds per square inch, and represents the force at which water enters your home from the water main. Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80.
Efficient shower heads use at least 1.5gpm. Taking the same amount of time in the shower uses only 15 gallons of water. The water savings amount up to 65 gallons of water!
The typical residential water flow rate for small households is between 6-12 gallons per minute, so unless you plan to add extra kitchens, bathrooms, or laundry rooms to your home in the future, your home will never need to exceed that final GPM, assuming your flow rate is already normal.
Yes. As there is a very close relationship between water flow and pressure, an increase in pressure also increases the flow rate. Therefore, changes in the pressure will directly change the flow rate.
This is a loaded question, that really comes down to preference and the number of individuals that are in the home. The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.
