BS1212 Part 1 Valves

BS 1361 part 1 is the British Standard for piston type float operated valves.

Often called a Portsmouth valve, these brass BS1212 part 1 float / ball-cock valves. are commonly used as a cold water tank inlet / fill valve.

Most household applications use a 1/2 inch ballcock valve, the bigger 3/4 and 1 inch sizes are very rarely (pretty much never), found in a domestic environment.
