With the release of WaterSense for showers, bathers can conserve without sacrificing performance.
Product Review: Water-Conserving Showerheads
- 600American Standard. The water-conserving FloWise showerhead line now includes a handshower that flows at 1.5 gpm in single-function and three-function models. The bather can set the three-function version to turbine spray, a 2.0-gpm full spray, or a combination of the two, and it includes an auto-return feature that re-sets the showerhead to the lowest flow function when the shower is turned off, says the firm. The showerhead comes in polished chrome, blackened bronze, polished brass, stainless steel, and satin nickel. 800.442.1902. www.americanstandard-us.com.
- 600Delta. Designed to imitate the scallops of a seashell, the Addison Raincan showerhead is WaterSense-certified and flows at rates of 1.5 gpm and 2.0 gpm. The showerhead features H2Okinetic technology, which forms larger droplets for more coverage, the firm says. The showerhead has a 6-inch face and comes in four finishes. 800.345.3358. www.deltafaucet.com.
- 600Jaclo. Pending WaterSense certification, the Leticia showerhead uses a flow regulator to maintain a constant flow rate over fluctuations in the supply pressure, says the company. The showerhead has a 3-inch face, a brass body, a swivel ball joint, and an easy-grip rubber ring for adjusting between five spray patterns: full rain, power rain, power spray, massage, and full rain massage. It comes in more than 20 finishes. 800.852.3906. www.jaclo.com.
- 600Kohler. The Purist oversized showerhead flows at 1.75 gpm and meets WaterSense specifications, the firm says. The showerhead has three spray options—wide, focused, and concentrated utility spray—and it includes a pressure-balancing valve for anti-scald protection and temperature regulation. The showerhead is also available as a handshower. 800.456.4537. www.kohler.com.
- 600Moen. The Envi Eco-Performance rainshower has a flow rate of 2.0 gpm and carries the WaterSense label. The 8-inch-diameter showerhead uses self-pressurizing technology to maximize spray power. It comes in chrome or brushed nickel finishes. The company has 16 other WaterSense-certified showerheads, including wall-mount, rainshower, and handshower models. 800.289.6636. www.moen.com
- 600Niagara Conservation. The WaterSense-certified Earth Massage showerhead flows at rates of 1.25, 1.5, and 2.0 gpm with a pressure compensator to keep the rate from fluctuating. The showerhead has nine jet options and comes in three styles: a wall-mount, a handheld with a 72-inch hose, and the Earth Soap & Soak, which includes a pause valve to stop the water while lathering. The showerhead is available in white or chrome finishes. 800.831.8383. www.niagaraconservation.com
- 398Price Pfister. The 1.5-gpm Eco-Pfriendly showerhead with Air Infusion Technology, which infuses air in the water droplets to amplify pressure, is WaterSense certified. It is available in a chrome finish. 800.422.4278. www.pricepfister.com.
- 600Toto. The Lloyd high-efficiency showerhead has a maximum flow rate of 1.75 gpm and a rubber nozzle to prevent lime scale and calcium buildup, says the company. WaterSense pending, the showerhead is available with a Shape Memory Alloy mixing valve to regulate temperature changes with a coil made of nickel and titanium alloy. The showerhead comes in a variety of finishes. 888.295.8134. www.totousa.com.
Thirty gallons of water disappear down the shower drain every day in the average household, according to the EPA, which is why the group added showerheads to its labeling program in early March. As with existing WaterSense standards for faucets and toilets, qualified showerheads not only must not exceed a maximum flow rate (2 gallons per minute, 0.5 gpm below the federal standard), but also must meet user-satisfactory pressure and coverage requirements.
"What we don't want to do is take a 2.5-gpm showerhead and put a flow restrictor in there and have it flow at 2.0 or 1.75 gpm and feel different or weak," says Mike Reffner, group product manager at Moen.
Simply choking down a showerhead can leave a weak spray or chilly dead spots; alternatively, blasting the water through smaller spray formers to increase the intensity creates a stinging sensation that is far from satisfying.
In consumer test reports, the EPA found bathers did not enjoy showerheads that spat water from a single, central jet, nor did they like a ring of drenching rain with an empty spot in the middle, so in order to earn a WaterSense label, the showerhead must pass the spray pattern criteria to ensure complete, even coverage. The standard also evaluates pressure compensation (i.e., how well the water flows at different pressures) and spray intensity (how effective the flow is for rinsing soap and shampoo). In addition, WaterSense set the maximum pressure at 80 psi to avoid needle-like sprays.
Makers have taken up the challenge, engineering larger droplets, experimenting with air induction and vacuum technology, or arranging the spray pattern in new ways, all to earn a low-flow label without the low-flow feel.
"A 1.5-gpm feels like a 2.5-gpm because the spray pattern oscillates and feels like it's enveloping you in a lot of water," says Delta representative Christiana Brenner of that manufacturer's new H2Okinetic technology, "but it's because the water droplets are slightly larger and coming at you from many different places."
"We have spent time and engineering resources to come up with solutions," says Moen's Reffner. "If you don't incorporate that kind of thinking into the product ... the efficiency is lost and instead of spending 10 minutes in the shower, you have to spend more time to rinse the shampoo out of your hair. So who wants to be frustrated by more time and really not saving anything?"
Using the mathematic Phi ratio found in organic designs such as plants, animals, and even galaxies, Moen's Biomimicry designs use nature's calculations to fit as many spray formers on the surface of the showerhead as possible for complete spray coverage.
Like traditional showerheads, WaterSense-certified units vary widely in price, from affordable to high-end. "People really don't want to spend a lot more if anything on [these] products. They want to be green, but they don't want to be told, 'Well, you have to pay X number of dollars more to save water,'" Reffner says.
The EPA says a $30 WaterSense showerhead will ideally pay for itself in roughly 14 months via water and energy savings.
And along with reengineering the products, manufacturers also are working to reverse consumer perceptions about water-conserving fixtures. "We like to call them 'high efficiency' because when people hear 'low flow,' they get a little scared and they think they're going to lose their water pressure," says Cecilia Hayward, marketing manager for Niagara Conservation. "The main challenge is educating people that low flow doesn't mean you're losing pressure; it just means you're saving water."
