- Abstract
The issue of water shortages is aggravated with increased pollution and global warming. Given that water usage from toilets constitutes the majority of domestic water usage, water-savings realized through toilet use is one of the most effective ways to resolve water shortages. Therefore, a comparative analysis of the flushing and water-saving performances of a flexible-trapway toilet was conducted in this research. In addition, the flushing performance of the toilet was quantized through the development of a measurement method to measure the accumulated flow rate and mass flow rate of the trapway with respect to time. As a result, the flexible-trapway toilet yielded stable flushing and good filth emission performance with an inflow of 4 kg. However, the fixed-trapway toilet failed to generate a steady siphon with an inflow of 5 kg. An ultra-water-savings toilet that combines a flexible trapway and pressure assistance will be developed in the future.
