One...two... flush level is up to you!
If the Mister Miser is just a bit too far of a leap for your household, or you require something more than a urinal to take care of business, you don't have to count yourself out of the green-toilet race yet. One solution is the dual-flusher -- two levels of water for two different occasions. Even if you already have a low-flow toilet this could still conserve up to 28 gallons per day! Some city or water companies will even provide a rebate for a dual-flusher. There's no time like the present to upgrade your john and save more water!
