What is it? A Pressure Regulator
I am sure many of my Montana friends have seen these adapters screwed on to the campsite water faucets. They look like a short pressure regulator--What are they really?
I have removed the last two I encountered because they leaked and I could not get my hose to seal properly even with a new washer. I usually leave them at the faucet so the next guy or the campground can re-install them.

They are back flow preventers.

I have noted that with some of them I have had to remove my water regulator in order to get water into the rig???

Back flow preventers--AH--that explains the spring loaded center section that will allow water out but not back into the campground system. Thanks for the free adult ed!

In many, if not all, commercial operations they are required to have these devices installed. First time I saw one I thought someone had forgotten their pressure regulator. Then realized the thing was mounted in such a way as to be very difficult to remove. I assume these things cost a dollar or two and the CG is not gonna want to constantly be replacing them.
Travel safely, Dennis

Our local water system out here in the boonies requires these on all outside faucets. Last about six months if you use them. 6 or 7 bucks at the Home Depot here. I think they are more of a vacum breaker than a true backflow preventer.

May have been my water pressure reducer. I left one on last trip.
Some people use them as a safeguard to make sure the water pressure is not too high. Normally not a problem, but we did stay at one park that actually had a warning that their water pressure was 140 lbs. I made sure to use it there.

Back Flow Preventer. I hate them, and especially when they have the allen set screw holding it on the faucet. To hard to remove. Depending on your pressure regulator you may not be able to screw it on because the pressure regulator screen filter will be in the way.

they are called anti siphon valve.they work when the water presure drops they stop the system from sucking water from any lines attached to the anti siphon vale. eg.. if you had a hose stuck in a pale of dirty water or anything contamating it would suck that up the hose and into the water system.this would contamitate the whole system through out the park and anything else on that line.the anti-siphon valve stops that from happening.

All you Fl folks should know what they are since by law you should have them on your home outside faucets.

In CA I think they are required in many counties for newer homes (I think this started in 2000). I have some at all the exterior faucets and they are round and punched at the sides so they can't be removed or tampered with. If something happens to my faucets it's gonna require replacing the whole faucet or cutting it off. I'm just dealing with it.

Fauch,
I think that the OP (original poster) meant Florida. But I've been wrong once before.

If there was a fire down the road and the fire truck was pumping from the fire hydrant it could cause a negative pressure on the entire water system. If this happened, any open hose from all the folks on this system would begin flowing back into water system thus drawing any contaminates into everyone's water. The back flow preventers may be a pain but not as bad as the pain of bacterial infection.
