How much water does dual flush save?

A: A technology first developed in the 1980’s, the dual-flush toilet takes water-efficiency one step further: using 1.6 gallons for solid waste and only . 8 gallons for liquid waste. Q: What kind of savings can I expect with a dual-flush toilet? A: Reduce water usage up to 30%.Click to see full answer. Likewise, do dual flush toilets really save water?Dual flush toilets are interactive toilets that handle solid and liquid waste differently by presenting the user with a choice of flushes. The fact is that the dual flush toilet technology can save up to 70% more water than a traditional low-flow toilet and that is all due to the way dual flush toilets work.Similarly, how much water do you use per flush? In a home with older toilets, an average flush uses about 3.6 gallons (13.6 liters), and the daily use is 18.8 gallons (71.2 liters) per person per day. In a home with ultra-low-flow (ULF) toilets, with an average flush volume of 1.6 gallons (6 liters), the daily use is 9.1 gallons (34.4 liters) per person per day. Consequently, how much water do dual flush toilets use? Dual-flush toilets use even less than the average, around 1.28 gpf, when averaging the full flush and the half flush combined. Typically the solid waste button will perform a regular flush (1.6 gallons) and the liquid waste will only use half the amount of water (0.8 gallons).Which is better dual flush or single flush?Single-lever flush systems are easier to operate since every flush is rated at 1.28 gpf. However, dual-lever flushing offers two choices, a “half flush” for liquids and a full 1.6 gallons for solids. For higher-traffic bathrooms, offering a single-flush choice may cut down on flushing confusion.
