ShowerStart Water Saving Device

This ingenious idea makes shower time more efficient in every way. Just screw ShowerStart between your showerhead and pipe, turn on the hot water, and walk away. As soon as exiting water hits 95øF, it's reduced to a trickle. Instead of conscientiously waiting for hot water to arrive, you're free to better use your time without worries about water or energy waste. You'll hear hot water appear, but relax! It'll be ready when you are with a simple switch that restores full flow. Fits all standard showerheads. Automatically resets after each use. Showerhead, pictured, not included. USA.
