Most toilets will rely on gravity to flush the water from the tank into the bowl  to force the contents of the bowl into the drain. These toilets are referred to as gravity-flush toilets due to this flush method. However, we  can also supply dual-flush toilets that use the same gravity-flush mechanism, but the user can choose between a low-flow flush or a strong flush. In any case the mechanism will have very good quality to be enough durable .

Similarly, some toilets are designed to increase the power of the flush in order to ensure that the contents of the toilet bowl get washed into the drain line. These toilets are generally referred to as pressure-assisted toilets. This additional force is possible because the toilet uses air pressure to increase the flushing power.
