Flush less water with a soda bottle

If you've got an older toilet in your house (not the High efficiency (HET) models), you're using more water per flush than necessary, which depletes resources and your wallet. Here's a simple trick that costs less than installing a new toilet.

Fill an old, plastic soda bottle with water and place it inside the tank. Let's say your family flushes the toilet five times a day. Since the bottle displaces exactly 2 liters of water, that's 10 liters you won't be pulling into your house (or paying for!).

Again, don't try this with a HET. But those of us with older models may give it a try.
