Water Smart

What kind of water fixtures do you have?

Pre-1992

Before 1992, the average toilet used 3.5 gallon per flush (GPF) and the average showerhead and aerator had flow rates of 5.0 gallons per minute (GPM).

or

Standard

After 1992, federal regulations mandated that toilets can’t use more the 1.6 GPF, showerhead can’t use more than 2.5 GPM and aerators can’t use more that 2.2 GPM.

Per Unit Averages¹

Based on an average of pre-1992 units and standard units found in the home water consumption would be 2.2 GPF for toilets, 3.25 GPM for showerheads, and 3.04 GPM for aerators.

The Stealth System

The Stealth^® uses 0.8 GPF. The Tri-Max Showerhead used an average of 1.0 GPM and all three aerators (Tri-max, versa, and the Low-Flow) combined use an average on 1.0 gallon GPM is beyond what federal regulations mandates.
