Float Valves (Ball-Cocks)

Float Valves (Ball-Cocks)

Brass and plastic float valves (ball-cocks), floats and spares for your cold water storage tank or toilet cistern.

The modern ball-cock was invented by José Antonio de Alzate y Ramírez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.

The threaded connections of these valves use a British Standard Pipe Thread size - see BSPT link at bottom of page for more info.
