"Fire hydrant" valve - wrong way round?

[Welly Warmer]

Hi, I am going to a job tomorrow where the customar says they have a 1 inch square valve head (what i would call a fire hydrant valve, maybe theres another name) in a manhole that turns the wrong way ie. Anticlockwise is off and clockwise is on.

I'm in the Midlands and customer says some water authorities/ counties have valves turning different ways.
Has anyone ever come across this?
Thanks

Would ask the water board if it’s anything to do with them

Hi Seaun thanks for your message. It's well on the customer property past the meter so it's probably not the water boards, im just intersted if anyone has come across a similar valve turning the wrong way? I take it you haven't? Thanks again! (Its on a 4 inch main going in to an old factory btw)

Probably attached to a gate valve then hence why it’s backwards

Also known as 'sluice valves'. See, for example

That seems insane that different towns/cities have clockwise/anti-clockwise within the same water board area!
