flushometer

Flushometer valves use pressure instead of gravity to direct water into the bowl.

“You work with the guys in the technical shops who say, ‘Don’t use that flushometer; it doesn’t work.’

The urinals in the men’s room look like some on the website of the manufacturer Toto, with the $1,071 flushometer valve.

Water closets and urinals must not be connected directly or flushed from the water-supply pipes except when flushometer valves are used.

Each water closet must be flushed from a separate cistern, the water from which is used for no other purpose, or may be flushed through flushometer valves.
