External Stop Cock Q.

[delb0y]

Calling on the collective power of cycle chat...

My dad used to turn this on and off all the time - so it can't be difficult - but I don't want to turn the wrong bit and do some damage or cause a flood. Anyone seen an external stop cock



like this before and, if so, advise whether one turns the hexagonal bolt in the middle or whether one turns the outer circular frame via the two semi-circular indents?

Many thanks
Derek

That looks like a flux capacitor. Be careful.

I have never seen anything like that before. Rather than it being a stopcock, it might be a blanking plate ready to be removed and a water meter put in its place ?
Of course, if you are already on a metered water supply then that theory would be wrong.

They are usually square headed.

Are you sure that's water ??

Its the Antikythera mechanism!

It's the cover to the detonator of a thermo-nuclear device. It's probably best left alone. If you do manage to open it, don't forget to cut the green wire before the blue one.

Whatever it is it's a work of art. Our external stop cock is a boring tap ☹️

Turn it via the two circular indents.

That's based on nothing more than it saying 'on' in the gaps next to it, and the fact it's not me getting soaked if I'm wrong.
