Showerheads are showerheads are showerheads right? Used to be but Not anymore. Showerheads, like toilets, are regulated by EPAct92, which established a limit of 2.5 gallons per minute (gpm; 9.5 liters per minute, or lpm) at 80 psi of water pressure. Because all showers use hot water, reducing water use also saves you the consumer energy.
Are you aware that replacing an older showerhead, (which flows at 5 gpm or more), with a unit that uses 2.0 gpm (8 lpm) or less, can pay for itself through reduced water and energy use in just a few months? You can't afford to wait any longer to start changing out those old shower heads.
Today the best showerheads are designed for water efficiency from the ground up. Some models do rely on the Venturi effect to aerate droplets and create the feel of a forceful shower while using relatively little water. But many other manufacturers, including Delta Faucet, have gone even further in showerhead redesign, by creating what is called a pulsed shower with large droplets. It is possible that you will see new standards on the horizon.
Right now the EPA's WaterSense* is working on a standard for showerheads that will likely bring us WaterSense-labeled products by the end of 2010 with a maximum flow of 2.0 gpm (8 lpm), or possibly lower. The current GreenSpec standard right now for showerheads is 1.75 gpm [6.6 lpm]. Most major plumbing manufacturers are developing methods of measuring the wetting performance and heat retention of their respective showerheads.
Many leaders in the plumbing industry believe that it is possible to incorporate such performance attributes into WaterSense standards. Multiple-showerheads have issues that may be addressed in some way in the next several years. But in general, these new regulations may prevent showerheads from being modified to increase flow above the legal limit.
