    Hack a Toilet for free water.

    Great idea! Japanese toilets have this feature, according to a museum in Boston...It absolutely does save water, TWICE, because:1. You won't use water in the bathroom basin to wash your hands - water that is then wasted down the drain.2. The water coming out of that tube is not what flushes the toilet bowl, but rather it is a vanity feature that makes a slow flow into the bowl after (and during) the main flush which is through the flapper valve in the bottom of the cistern. That vanity feature is just to ensure any remaining "colored" water in the bowl is diluted or displaced while the cistern fills, and is actually unnecessary.3.

Better saving yet is to do exactly what this instructable shows to use that vanity trickle to wash your hands, and THEN fill the tank faster with it - the water saving is a double whammy!Thanks for the instructions,M

    The funnel does not actuallly need to go into the overflow tube, but can just go to fill the cistern - even better
