Even though most people want to conserve water and know that water conservation is important for the health of our planet, few people realize how much water they are using when they flush the toilet. Traditional toilets use several gallons of water per flush, and in a busy household of four, the amount of water needed for toilet flushing can be quite significant. This is especially true if your toilet is older (pre-1992) - in this case it can use up to five gallons of water each time you flush. Toilets manufactured after 1992 were required to be designed to use 1.6 gallons of water or less for each flush. And while this is a great savings in terms of water used per household, we can still do better by installing a dual flush toilet.
These green plumbing products provide the most efficient means of flushing and uses the least amount of water to do so. A dual flush toilet has two separate flushing mechanisms; one is for a short flush, the other for a full flush. This allows the user to choose the amount of water that they need for each use as the short flush is engineered to flush away fluids while solids are better dealt with using a full flush. Even when used on full flush mode, the dual flush toilet typically uses less than one gallon of water and provides optimal performance.
