Can you please give me more information and suggestions on water-efficient showering?
In many areas, a new showerhead can use up to 2.5 gallons of water per minute or GPM. In some areas the GPM may be reduced to a lower number, so find out what your local flow rate is per showerhead and follow those codes. Flow rates for most showerheads should be noted in the product information.
Today, many showerhead manufacturers have come up with clever ways to make the shower spray feel more powerful while still being water-efficient at less than 2.5 GPM. One of those ways is called “air-induction” technology. Air-induction showerheads can automatically mix air into the water flow, creating a larger, fuller spray that can feel stronger than a standard shower spray.
Some efficient showerhead setups even offer a “high-low feature” that can change the water flow rate from 1.5 GPM to 2 GPM with the press of a button. This way you can have the constant flow of warm water for washing and the selected power boost for rinsing.
Bottom line: A high-low shower can offer savings and power.
