A flushing tank, also known as a flush tank or cistern, is a component of a toilet system designed to store and release water for flushing. Positioned above the toilet bowl, it operates via a lever or button mechanism that opens a valve to release a controlled amount of water, effectively cleaning the bowl and transporting waste to the sewage system. Flushing tanks come in various sizes and designs, often incorporating water-saving features to reduce water consumption. Modern tanks may include dual-flush options, allowing users to select a partial or full flush, promoting efficiency and environmental sustainability.
