Sh*t, Shower, & Save

Here's how:
Place a wash basin under tub when adjusting water temperature for your shower. Then dump water directly into toilet and watch the flush happen w/o pressing the lever. That’s right; you just saved 6+ gallons of water. The water that normal flows uselessly down the tub drain has provided a free flush for your toilet. The wars of the future will be fought over and for water, so give a hoot and postpone the inevitable a bit longer.
