Gravity-tank toilets draw water from their attached tank to supply a low-pressure flush in small buildings, hotel rooms, homes, and other low-traffic settings (20 to 30 flushes per day). Also called gravity-fed toilets, these fixtures rely on a gravity to move water from the tank into the toilet bowl for flushing. Compared to tankless and pressure-assist toilets, gravity-tank toilets have a quieter flush and a simpler design that typically allows easier maintenance and repairs. They are the most widely used style of toilet and work with smaller pipe sizes that prevent the use of tankless toilets.
