BS1212/3 Part 3 Valves

BS1212 part 3 is the British Standard number for diaphragm type plastic float operated valves.

Part 3 float / ball-cock valves look like part 2 valves and operate in the same way – the main difference is that they are made from plastic instead of brass.

Part 3 ballcock valves are typically used as fill valves in older handle flush WC toilet cisterns.
