We covered it briefly in our series on ways to conserve water, so don’t forget you can make a toilet tank filler out of an old water bottle. Doing this can save you 10 gallons-yes TEN gallons!- of water a day.
And it’s so simple to create:
Put a couple inches of sand or very small rocks in the bottle. Fill the bottle with water the rest of the way and place it in your toilet tank. Viola!
