Dual flush toilets are great and practically have no downsides to them because they only use about 0.8 gallons of water per flush for a simple flush and about 1.8 gallons of water for solid waste flushing. When you compare the two types of toilets you will realize that dual flush toilets use about 4.5 gallons of water less than the conventional low flow toilets do.
The American Water Association has conducted a study that revealed that an average person’s annual water expenses will reduce on average by about $250 with dual flush toilets. The Federal Energy Policy Act has introduced a water limit of 3.5 gallons for low flush toilets back in 1992 before that regular outdated toilet models could use up to 8 gallons of water per flush regardless of whether the bowl had liquid or solid waste.
Moreover, those models were notorious for needing more than one flush for solid wastes anyway otherwise the toilet bowl would be filled with waste left behind. Since then, a lot has changed and the latest models are designed to be eco-friendly and as water-efficient as possible. Toilet manufacturers have come up with various ideas to save water and among their designs is the dual flush toilet that uses the least amount of water when compared to any other type of toilet.
Plus, nowadays American water management companies are encouraged to offer incentives to individuals implementing more efficient dual flush toilets as this reduces the amount of waste that gets sent to waste processing plants as well as water treatment reservoirs. Some city and county administrations go the extra mile and give store credit to individuals looking to replace outdated toilet models with more modern and efficient ones.
