Flush mechanisms are devices used in toilets to remove waste from the bowl. When the user presses a button or pulls a lever, water from the tank flows into the bowl, carrying waste through the plumbing system. There are different types of flush mechanisms, including gravity-fed systems and pressure-assisted systems, each functioning to ensure effective waste removal. Gravity-fed systems rely on the weight of water to create a flush, while pressure-assisted systems use compressed air to force water into the bowl. Both types aim to provide a reliable and efficient way to maintain hygiene in bathrooms, contributing to overall sanitation in homes and public facilities.
