Federal law resticts shower head flow to less than 2.5 gallons per minute for new shower heads. Most shower heads will use the maximum since "shower satisfaction" goes down with lesser amounts. This dissatisfaction results in some products being sold, such as The Giant, with very clearly worded advertisements stating that the shower head is ineffective at 2.5 gpm, with thinly veiled descriptions of the ability to defeat the water restrictor.
