These are the different flushing technologies available for your toilet:
Gravity-feed toilet: The most common and simplest toilet flush type, which uses the force of gravity on water weight from the tank to flush and siphon waste through the trapway. Known as having a quiet flush with minimal parts, so repairs and maintenance are simple and minimal compared to the pressure-assisted toilet.
Pressure-assisted toilet: Here’s your power flush option for a higher price tag. Using pressurized air forces water and waste down harder, farther, and faster for a more efficient and powerful flush. It makes a little more noise, but fewer clogs happen in pressure-assisted toilets. A good choice for a high-use toilet, though maintenance might be costly if needed.
Dual-flush toilet: A newer type of toilet that’s gaining popularity for its water-saving efficiency. A hybrid of the gravity-feed and pressure-assisted toilet, there are two flushing options: a half flush for liquid waste (~1.1 gallons of water) or a full flush (~1.6 gallons of water) for the heavier matter. The half flush utilizes the gravity-feed flushing mechanism, whereas the pressure-assisted flush handles the more heavy duty full flush.
Double-cyclone toilet: A newer technology, double-cyclone toiletry uses minimal water for a powerful and efficient flush via two “cyclone” nozzles to usher the water and waste down the piping, as opposed to the little holes in the rim water is usually pushed through in other models.
Waterless toilet: These self-contained toilets don’t use water or plumbing, so the waste is kept within a receptacle inside the toilet for places or situations where water or plumbing isn’t available. Good for camping, worksites, tiny homes, and other portable locations.
