Ball-cock Valves

BS1212 is the British Standard number for brass and plastic ballcock valves in cold water tanks and WC toilet cisterns .

We have a great range of valves and spare parts.

Typical applications :

BS1212/1 Part 1 brass float / ball-cock valves are used in older cold water tanks and central heating feed and expansion header tanks.

BS1212/2 Part 2 brass float / ball-cock valves are used in modern cold water tanks and central heating feed and expansion header tanks.

BS1212/3 Part 3 plastic float / ball-cock valves are used as inlet / fill valves in handle flush WC toilet cisterns.

BS1212/4 Part 4 plastic float / ball-cock valves are used as inlet / fill valves in modern WC toilet cisterns.

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