The perfect balance between conservation and convenience.
The "default" position of this aerator is .5 gallons per minute (gpm), the lowest flow rate available in a circular spray pattern. Push down on the black ring for a full 2.2 gpm aerated stream flow.
Use the default flow for washing hands and dishes, brushing teeth, etc and the full flow for filling pots.
Connects to most faucets with inside or outside threads, easy installation, no tools needed. Dual threaded 15/16" - 55/64".
THE perfect aerator if conservation is your goal.
Note: The water must be ON when you are switching to the full 2.2 gpm flow. Once you turn off the water, it resets to 0.5 gpm. Similarly, you can't push it down and then turn on the water - it will not stay down. You must do it when the water is full on.
