Which device is located at the bottom of a tank for flushing fixtures?

The flush valve is a crucial component located at the bottom of a tank, typically found in toilets or similar fixtures. Its primary function is to control the release of water from the tank into the bowl when the fixture is flushed. When the flush mechanism is activated, the flush valve opens, allowing water to flow rapidly from the tank to the bowl, facilitating an effective flushing action that removes waste.

This device operates under principles outlined in plumbing codes, which emphasize the importance of ensuring adequate flow and pressure during the flushing process. The flush valve is engineered to create a seal when not in operation to prevent leaks, thus maintaining efficient water usage and compliance with building codes.

In contrast, a flushometer is a different device used primarily in commercial settings for flushing toilets without a tank, while a shower valve controls water flow and temperature in a shower setup. The pressure regulator serves to manage and reduce incoming water pressure but does not directly facilitate the flushing mechanism in toilet tanks. Understanding these distinctions reinforces the importance of selecting the correct plumbing components based on their functions as outlined in the Kentucky Plumbing Code.
