Water-saving showerheads that earn the WaterSense label must demonstrate that they use no more than 2.0 gpm. The WaterSense label also ensures that these products provide a satisfactory shower that is equal to or better than conventional showerheads on the market.
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.
Manage Water Waste
As recently, shower heads typically delivered water at a rate of around 5 to 8 gallons per minute! Today, the standard for a regular shower head is around 2 and a half gallons per minute. Low flow shower heads will typically deliver water at around 2 gallons per minute.
Kohler K-22169-G-CP Forte Shower Head 1.75 GPM
Without a doubt the best overall option in this guide, the Forte 1.75 GPM shower head from Kohler does everything you need. Using air-induction technology to offer water saving service, this multifunction shower head still gives you the perfect shower every time.
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.
Many modern shower heads are designed specifically to increase the pressure of the water coming out of the showerhead itself. So, while they can't increase the actual water pressure of the home, they do improve the showering experience.
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.
Saving Water Saves Money
With a low-flow showerhead, 175 minutes of showering uses just 262 gallons of water. Which means you save about 60 percent every month. Translate that to yearly figures, and a 1.5 gpm showerhead uses just over 3,100 gallons of water versus over 5,200 with a 2.5 gpm model.
For water conservation purposes, most plumbing codes require faucets and showering devices to not exceed a certain maximum flow rate. Removing the flow restrictors could cause these devices to no longer meet these codes.
After all, it needs certain amount of water to remove the soap, that is physic. Studies have shown that 1.8 gpm is the minimum flow rate to have a good enjoyable rinsing, so the common 1.75 gpm models, is somewhat good enough for a decent shower. To save water further and still have a full enjoyable rinsing experience.
Two big reasons: To help lower utility bills -- and to conserve water. According to the EPA, the average family could save 2,700 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy.
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.
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.
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.
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 Water Well Board suggests that a minimum water supply capacity for domestic internal household use should be at least 600 gallons of water within a two-hour period once each day. This is equivalent to a flow rate of 5 gallons per minute (gpm) for two hours.
A standard 2.5 GPM shower head uses 2.5 gallons of water each minute. That's 25 gallons for a 10-minute shower. VS. A low-flow 1.8 GPM shower head uses 1.8 gallons of water each minute.
Residential household toilets must use no more than 1.28 GPF (gallons per flush). Residential bathroom faucets must use no more than 1.2 GPM (gallons per minute). Residential showerheads, including handheld showers and fixed body sprays, must use no more than 1.8 GPM.
If your water pressure seems low, the first step should be to test how much pressure you're actually getting from the shower head. A typical home's water pressure should be somewhere between 45 to 55 psi (pounds per square inch).
Most low-flow showerheads have a rubber pressure-reducing valve (called a regulator) to maintain a lower pressure. You can increase the flow by simply taking it out. You could also consider enlarging the hole that allows water into your showerhead with a drill to increase the amount of water coming through.
Many people don't realize it, but shower heads should actually be replaced every 6 to 8 months.
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.
