Older toilets use about 3.5 to 7 gallons per flush. Low flow toilets use only 1.6 gallons per flush and save your family between 8,000 and 20,000 gallons of water per year, per toilet. Dual-flush toilets take savings to the next level, because they have two buttons - one for a light flush at 0.9 Gallons and the other for a heavy flush at 1.6 gallons.
Dual-flush toilets have been very popular in Europe and Asia for years. They save an average of approximately 26 per cent more water than single-flush 'Low-Flow' models, and you can control when you need more or less water.
The ROI Calculation is based on a typical toilet costing about $150 and the dual-flush models costing about $300 with an average savings of 15,000 gallons and the cost of water at about $1.50 / 1,000 gallons.
The elegant flushing device is about as simple as can be… the left side = light flush and the right side = heavy flush. You decide, and save thousands of gallons each year.
