The problem:

Standard showerheads installed after 1992 use 2.5 gallons of water per minute. Older showerheads can use double that. So every 10 minute shower uses 25 gallons of water. The solution – switch to low flow showerheads. What was once a phrase spat with contempt, low flow showerheads have come leaps and bounds from 10 years ago.

The solution:

Today’s low flow showerheads use 1.5 or 1.75 GPM of water – a savings of 40%, or a gallon for every minute you are in the shower. Those savings easily add up when you look at households of 4 that have multiple showers a day, or hotels with hundreds of rooms and showers every morning.

Be careful though, almost every 2.5 GPM shower still advertises itself as “low flow”. This misnomer must be carefully examined when you are shopping for new showerheads.
