This is the Sloan Regal 110 Exposed Manual Water Closet Flushometer, 3.5 GPF Manual Fl, a Sloan flushometer — the diaphragm or piston flush valve that meters a precise, high-pressure flush for a commercial toilet or urinal. Sloan invented the modern flushometer, and these are the workhorses found in schools, offices, stadiums, and public restrooms.
Built for years of heavy daily use, it delivers consistent, water-efficient flushing and is serviceable with standard Sloan repair parts rather than full replacement. Choose the model that matches your fixture’s spud connection and flush volume.
Sloan Valve Company has manufactured commercial plumbing systems in the USA since 1906, from its Franklin Park, Illinois headquarters — the company that invented the modern flushometer and remains a leader in water-efficient commercial restroom fixtures.
