On a fire hydrant that is .....
I see that a lot here, they use the hydrant for a temp source until the main supply is ready. I also see pool trucks fill-up off of them with a meter attached.
It looks like there is a meter on this on too. Is that an actual legal testable backflow assembly though? Not sure if that's a testcock or not. I also not sure that there would only be one gate valve on a legal assembly.
It looks like the city water dept installed that.
We can rent/buy hydrant meters here in wilson, they come read the meter once a quarter. It comes with a 2" rp backflow
Here the spray trucks use hydrants to fill their tanks and eithe have a BF device or air gap

Good eyes. I certainly would not pass that valve with one gate valve. Looks to be modified and possibly missing test cocks.
It's a temporary hookup, most likely as Greenmonster stated: street sweeper trucks with water sprays. No testcocks needed.
why not just use an air gap?
I would have hoped that an assembly that was propped up with a block of wood would have been a temporay hookup, but that doesn't mean that it doesn't have to be safe and tested.
Here our Regional District has two RP's that are equiped with quick connect fire connections. They are rotated between 14 trucks or mounted on hydrants when needed. I test them twice a year.
That's a weird lookin hydrant. I'm surprised they don't have it coned off.. Tripping hazard????
