Toilets typically use 1.5 to 3+ gallons of water per flush. Unless the toilet uses a special gray water system, it uses the same tap water as your sinks and showers.

To save some of this water, place your water bottle in your toilet tank. This will keep the bottle out of the landfill and save water every time you flush! This method reduces the amount of water your tank uses by taking up some of the volume. This is an idea adapted from the '70s, when folks placed bricks in their tanks, which is not recommended as it can damage the plumbing (http://consumerist.com/consumer/home/should-i-put-a-brick-in-my-toilet-to-reduce-water-use-267872.php)

I used pictures from this instructable: http://www.instructables.com/id/Conserve_Water_Convert_your_existing_toilet_into_/ as my camera is out of commission

Step 1: Fill the bottle

First, fill the bottle with something that will make it more dense than the water in the tank. In other words, fill it with something that will make it sink to the bottom.

Of course you could fill it with water, which is okay, but in the spirit of conservation, you may want to fill it with other, more dense materials such as little tiny rocks, apples, or dare I say, a duck..

<p>The rebuild kits Depot sells are easily adjustable (a screwdriver) as to preferred water level. I can't figure out why wax rings with the inevitable failure rate are still in use.</p><p>zapp</p>
why not just adjust the flushing &quot;bobber&quot; i dont know what it is called, but the rubber bubble at the end of the arm. you use that to adjust the water level in the toilet if you dont want to put bricks and water bottles in it anyways.
thanks, that sounds like it would accomplish the same thing to save water! but don't you just really want to put a water bottle in your toilet tank? haha
1st comment! Such a simple trick, and it does work, I've been doing this in my homes for the last 20 years or so, and yeah, I did the brick thing at one point too... Nice to see it on this website!
