This is maddening! I am stationed in Germany, and am in recent times trying to water my lawn. The German stores hold only plastic hose couplings that are the threaded-to-quick-disconnect variety (as are the sprinkler attachments and so on). The hoses are rather flimsy, and the water pressure will cause the fittings to come apart if I close the nozzle at the hose stop when I am washing the car or something resembling that...so, I bought an American hose on base with standard brass threaded ends and a sprinkler for my grass.
When I attach the hose and turn on the water, the anti-siphon valve (small hole within the bottom of the spigot) shoots out water. This happens when the other running out of the hose has nothing attached, and wet flows readily from the hose, so I would be surprised if it were a backpressure issue. The problem happens on two separate outdoor spigots...what am I missing?
Answers: Could it be the difference between American weigh and Metric measure? The hose seems to fit and screw tight, but nearby could be even a millimeter difference which would cause a spray. I'd first use some teflon tape and an extra washer. Then...
If river pressure is the problem, get a reducer. The unit I own reduces the size from a half inch to a quarter inch. They work much similar to the water savers we adjectives use in our showers.
